In this respect, the presentation of the exogenous FVIII may not be sufficient for initiating an immune response. In the presence of danger conditions (i.e. severe bleeds, trauma or surgery with major tissue injury), the foreign protein is intensively presented (high-dose and/or prolonged treatment) in association with signals

that up-regulate the cellular T and B lymphocyte response. On the other hand, regular exposure to lower doses of antigen, in the absence of danger signals, which occurs in regular prophylaxis, may induce the tolerization of the foreign protein. This hypothesis is supported by recent studies showing a key role of the intensity of treatment at the first FVIII exposures: both in the CANAL cohort, which investigated selleck products 366 consecutive previously untreated children (PUPS) born between 1990 and 2000 from 14 centres in Europe and Canada [24], and in the combined analysis of data on 236 patients (FVIII <2%) from the four recombinant FVIII (rFVIII) registration PUPS studies [25], surgical and prolonged (≥5 days) FVIII exposure at first treatment,

and high FVIII dose (≥50 IU/kg) during the first 50 ED were associated with a twofold to threefold increase in the risk of inhibitor development. www.selleckchem.com/products/icg-001.html These data are also likely to explain the higher risk of inhibitor development in patients with an early age at first FVIII exposure, detected in previous studies and only at univariate analysis in the CANAL and other studies (Table 1). For this reason, an intensive treatment at initial exposure has been considered the most significant determinant (three points) in the prognostic score determined from the CANAL data [10]. This see more score includes the genetic factors previously mentioned (high-risk F8 mutation and positive inhibitor family history, each two points) and may

help to identify patients at high (>50%, score ≥3), intermediate (about 25%, score 2) or low (about 6%, score 0) risk of inhibitors. In agreement with the ‘danger model’, the CANAL study [24] and a previous case–control Italian study [26] showed by regression models, which take into account other potential inhibitor risk factors, a 60–70% reduction in inhibitor risk in patients on regular prophylaxis compared with those receiving on-demand treatment (Table 1). The most controversial issue of treatment-related risk factors remains the type of FVIII concentrate administered [1]. The CANAL study also investigated the risk of inhibitor development with respect to plasma-derived vs. recombinant products, and switching between FVIII products [27].

43 The sulfonamide then binds covalently to key cysteine groups on the extracellular domain of the proton pump to cause prolonged inhibition of the gastric acid secretion. Acid secretion is generally only restored through the recruitment of pumps that were previously at rest in the cytosol or the synthesis of new pumps (H+K+-exchanging ATPAse), which have a synthetic half life of approximately 50 h.44 The proton pump inhibitors all have similar short plasma half lives of elimination at

approximately 1 h and since they rapidly concentrate in the acidic secretory canaliculus Navitoclax are unlikely to accumulate elsewhere in the body.45–47 All of the PPIs are highly protein bound (> 95%) and rapidly metabolized by the liver with negligible renal clearance.48 Most PPIs are metabolized predominantly through the cytochrome P450 (CYP) enzyme systems, more specifically through CYP2C19. The majority of omeprazole metabolism

occurs through his pathway, while esomeprazole >  pantoprazole > lansoprazole are less metabolized via this pathway. Rabeprazole is the PPI least metabolized via CYP2C19; the majority of its metabolism occurs via a non-enzymatic pathway.28 Genetic polymorphisms of CYP2C19 expression account for the main inter-individual differences in PPI metabolism. However, the evidence for clinically significant sequelae from such interactions MI-503 as a result of inhibition of CYP450 has been conflicting.28,49,50 Study of the pharmaco-dynamics of clopidogrel and PPI demonstrates that they are very rapidly metabolized by the cytochrome P450 system and the authors suggest the chance of interaction would appear to be minimized. This review of the evidence regarding the apparent PPI and clopidogrel interaction is instructive from a number of perspectives. First, it is clear that in patients on clopidogrel and/or aspirin, bleeding results in significantly worse outcomes

Second, co-prescription of a PPI reduces bleeding and is incorporated into the current American Heart Association and American selleck chemical College of Gastroenterology guidelines, which recommend the use of a proton pump inhibitor (PPI) for the prevention of gastrointestinal bleeding in patients on antiplatelet therapy who are at high risk of bleeding.9 Third, examination of the pharmaco-kinetics and -dynamics of clopidogrel and PPIs, suggest that the opportunity for interaction between the two agents is limited, given the rapid concentration of the PPIs (weak bases) in the acidic secretory canaliculus and rapid metabolism of both PPIs and clopidogrel into their respective metabolites. Finally the available clinical evidence for the clopidogrel and PPI interaction is open to serious criticism and certainly not unequivocal.

These unsupervised investigations revealed that a gene network associated with cholestatic liver disease was the most statistically overrepresented network in pregnant, cholate-fed, and Fxr−/− mice (Fig. 2E). Therefore, global expression analysis demonstrates that pathways and networks regulated under conditions of bile acid overload or genetic cholestasis are also significantly affected by pregnancy. We aimed to determine whether hepatic genes respond to the accumulation of bile acids during pregnancy or are more likely

to be causative for the raised bile acid concentrations. To this end, we performed qRT-PCR assays on genes known to maintain bile acid homeostasis. These assays also served to confirm changes detected by microarrays. As expected, in cholate-fed MG-132 cost mice, the data were consistent with the adaptation of gene expression of bile acid homeostasis genes by Fxr activation. As such, cholate feeding induced hepatic Shp and Bsep expression, whereas Cyp7a1 and Ntcp expression was repressed (Fig. 3). In contrast, Fxr−/− mice showed elevated Cyp7a1 levels and reduced Bsep, Shp, and Mdr1a levels (Fig. 3). Despite the presence of elevated hepatic bile acid concentrations, there was no evidence of Fxr activation in pregnant mice. Although Fxr protein levels were unaltered, the messenger RNA (mRNA) expression of the Fxr target gene Shp was significantly repressed (−2.8-fold; P < 0.01) during pregnancy, whereas its

targets for repression, the bile acid biosynthesis enzymes Cyp7a1 and Epigenetics inhibitor Cyp8b1,8 were up-regulated 1.6-fold (P < 0.05; Fig. 3). Similarly, pregnancy significantly reduced the expression of hepatic import genes [Ntcp, organic anion-transporting polypeptide 2 (Oatp2), and Oatp4] and export genes [Bsep, Mdr1a, and multidrug resistance–associated protein (Mrp3); Fig. 3]. Defective Fgf15 signaling from the intestine could contribute selleck chemicals llc to the observed bile acid phenotype,9 but this does not seem to be the case because the expression of Fgf15 in the terminal ileum was unaffected

by pregnancy (data not shown). Therefore, raised hepatic bile acid concentrations during pregnancy do not result in hepatic or intestinal Fxr activation. Instead, hepatic gene expression during pregnancy is procholestatic and resembles a state of Fxr inactivation because the majority of these genes are directly or indirectly regulated by Fxr. Our data indicate that hepatic bile acids accumulate in pregnant mice as a result of procholestatic gene expression resembling reduced Fxr function. We therefore assessed whether enhanced Fxr target gene transcription is sufficient to prevent further accumulation of hepatic bile acids during pregnancy. Indeed, hepatic bile acids did not further accumulate in pregnant cholate-fed mice (Fig. 4) in which anticholestatic mechanisms (such as the induction of Shp, Bsep, Oatp2, Mrp3, and Mdr1a and the repression of Cyp7a1 and Cyp8b1) were already induced (see Fig. 3).

The frequency of antigen-specific ASC was calculated as a percentage of total IgG-producing cells. The

limit of detection (LD) was found to be three spots per well. These three spots were used to calculate the LD as a percentage of total spots obtained for IgG-producing cells for each individual patient. We set up an in vitro culture system that is suitable for studying the regulation of FVIII-specific memory B cells [17,18]. For this purpose, we obtained spleen cells from haemophilic mice treated with human FVIII and depleted these spleen cells of CD138+ ASC. Thereby, we generated a CD138− spleen cell population that did not contain any anti-FVIII ASC (Fig. 1) but contained FVIII-specific memory B, T cells and other cells. When we stimulated this CD138− cell mixture with human FVIII, FVIII-specific memory B cells were re-stimulated and differentiated into Y-27632 solubility dmso anti-FVIII ASC that could be detected as soon as 3 days after re-stimulation (Fig. 1) [17]. The maximum of newly formed anti-FVIII ASC was observed 6 days selleck inhibitor after re-stimulation (Fig. 1) [17]. In further experiments, we found that the re-stimulation of FVIII-specific memory B cells in our in vitro culture system

strictly depended on the presence of activated T cells [17]. Furthermore, a direct cell-to-cell contact between FVIII-specific memory B cells and activated T cells was required [17]. Based on our finding that activated T cells are required to re-stimulate FVIII-specific memory B cells in our in vitro culture system, MCE公司 we wanted to identify the specific co-stimulatory interactions that would be necessary for this process. Furthermore, we were interested to find out whether blocking essential co-stimulatory interactions would prevent the re-stimulation of FVIII-specific memory B cells. We added blocking antibodies against CD40L, CD80 (B7-1), CD86 (B7-2), ICOSL or recombinant competitor proteins (mICOS/Fc, mCTLA-4/Fc) to the CD138− spleen cell cultures immediately before re-stimulation with FVIII to study the importance of the relevant ligand

receptor pairs. The blockade of B7-CD28 or CD40-CD40L interactions significantly inhibited the re-stimulation of FVIII-specific memory B cells (Fig. 2) [17]. Both CD80 (B7-1) and CD86 (B7-2) contributed to the required co-stimulatory interactions with CD28. Blockade of both molecules prevented the re-stimulation of memory cells almost completely, whereas the blockade of only one of the two molecules resulted in a partial blockade (Fig. 2) [17]. The negative control antibodies and human IgG1 (negative control for mCTLA-4/Fc) did not show any effect. In contrast to CD40-CD40L and B7-CD28 interactions, ICOS-ICOSL interactions did not contribute to the re-stimulation of FVIII-specific memory cells. Neither the addition of a blocking antibody against ICOSL nor the use of a recombinant competitor protein (mICOS/Fc) resulted in a significant alteration in the re-stimulation of memory B cells (Fig. 2) [17].

Understanding the precise defect for each mutation may ultimately lead to better diagnosis and treatment. “
“Summary.  Everolimus concentration The standard treatment for end-stage osteoarthritis of the ankle joint in haemophilic patients has been fusion of the ankle joint. Total ankle replacement is still controversial as a treatment option. The objective of this prospective study was to evaluate the mid-term outcome in patients treated with total ankle replacement using an unconstrained three-component

ankle implant. Ten haemophilic ankles in eight patients (mean age: 43.2 years, range 26.7–57.5) treated with total ankle replacement were followed up for a minimum of 2.7 years (mean: 5.6, range 2.7–7.6). The outcome was measured with clinical and radiological evaluations. There were no intra- or peri-operative complications. The AOFAS-hindfoot-score increased from 38 (range 8–57) preoperatively

to 81 (range 69–95) postoperatively. All patients were satisfied with the results. Four patients became pain free; in the whole patient cohort pain level decreased from 7.1 (range 4–9) preoperatively to 0.8 (range 0–3) postoperatively. All categories of SF-36 score showed significant improvements in quality of life. In one patient, open ankle arthrolysis was performed because of painful arthrofibrosis. For patients with haemophilic osteoarthritis of the ankle joint, total ankle replacement is a valuable alternative treatment to ankle fusion. “
“Outcome assessment in haemophilia is important to assess results of prophylactic treatment. Recently, the Haemophilia Joint Health Score (HJHS) was MCE developed to assess early joint Vemurafenib purchase damage in children with haemophilia. Thus, the aim of this study was

to assess reliability and explore validity of the HJHS in teenagers and young adults with haemophilia. Twenty-two patients with haemophilia (mean age 20.4, range 14–30, including 15 severe) were assessed by the HJHS1.0, Haemophilia Activities List (HAL), SF36 and self-evaluation was performed using a Visual Analogue Scale (VAS) scale. A subset of 12 patients were assessed by three physiotherapists to establish interobserver reliability (intraclass correlation coefficient: ICC). Total HJHS1.0 scores were calculated without overall global gait. Validity was explored by the assessment of Pearson’s correlation with all outcome parameters and recent Pettersson scores. Overall outcome was good, with median HJHS score of 5.5 of a maximum 144 (range 0–34), median patients’ VAS of 96.5 and maximum scores for HAL and SF36 physical functioning for the majority of patients. Pettersson scores were low (median 3.5 of 78, N = 18). Interobserver reliability was good (ICC 0.84), with limits of agreement of ±7.2 points. ICC was unaffected by different score calculation methods. Exploration of validity in 22 patients showed weak correlations of HJHS scores with patients’ VAS (0.33) and HAL (−0.40) and strong correlations with SF36-PF (−0.66) and Pettersson scores (0.

Soft tissue tumor was suspected and biopsy was performed. Initial colonoscopic histopathological examination revealed chronic proctitis with lymphoid aggregates and atrophy. For more confirmatic diagnosis, soft tissue tumor excision was performed under general anesthesia. Histopathological examination revealed plasma cell infiltration and fibrosis. Immunohistochemistry revealed prominence of IgG4-positive plasma cells and confirmed the diagnosis of IgG4-related disease. The patient is currently under observation on low-dose PLX4032 order oral prednisolone with no evidence of relapse. Conclusion: Our case demonstrates that IgG4-related disease is difficult to diagnose preoperatively and

needs a steroid therapy. IgG4-related disease in low rectum is an extremely rare case. Here we report a patient with IgG4-related disease of the low rectum. Key Word(s): 1. IgG4-related EPZ-6438 nmr disease; 2. rectum; 3. young patient Presenting Author: JAMES EMMANUEL Additional Authors: RUBEN RAJ, JAYARAM MENON, RAMAN MUTHUKARRUPAN, SULIONG CHIN, YE MYINT KHIN, OO THA NAING Corresponding Author: JAMES EMMANUEL Affiliations: Queen Elizabeth Hospital, Kota Kinabalu, Queen Elizabeth Hospital, Kota Kinabalu, Queen Elizabeth Hospital, Kota Kinabalu, Queen Elizabeth Hospital, Kota Kinabalu, University Malaysia Sabah, University Malaysia Sabah Objective: General objectives: 1. This study aims to identify the possible barriers to the implementation of the screening

programme such as public perception and awareness of the disease and importance of screening. 2. To make possible suggestions to overcome the barriers to implement a successful programme in the future. Specific objectives: 1. To determine the awareness of colorectal cancer and screening in the general population. To determine if the public is willing to partake in a screening programme if introduced. Methods: A random sample of 245 adults received a self administered questionnaire on socio-demographic characteristics, knowledge on colorectal cancer risk and screening tools, attitudes regarding perceived risk of developing CRC, utility

of screening test and source MCE of information. Results: Only 27.3% identified low physical activity (modifiable risk factor) as a risk factor for colorectal cancer. There was a significant difference on the level of knowledge of familial history of CRC as a risk factor for CRC between both genders whereby the male population was more aware of this. About half of the respondents identified colonoscopy as a screening tool. Those with a higher level of education were more knowledgable in identifying the accepted tools for CRC screening (FOBT/colonoscopy/barium enema). Two thirds of the respondents have not received any information of CRC in the past. Personal opinion that screening is useful in CRC prevention was high with a mean of 7.4. 82.8% of the respondents agreed that CRC may be treated when diagnosed at an early stage and 86.

01) higher CK-18 fragment levels (8.69- ± 0.75-fold increase; Fig. 8C). Similarly, treatment with nontargeted scTRAIL and BZB induced a significantly (P < 0.01) higher cell-death rate (6.98- ± 1.00-fold increase, compared to untreated control), compared to EGFR-targeted scTRAIL combined with bortezomib (2.91- ± 0.28-fold increase; Fig. 8D). Thus, in combination with BZB, EGFR-targeted scTRAIL showed only marginal toxic effects on inflamed liver tissues, in Ivacaftor cell line contrast to nontargeted scTRAIL, which strongly induced toxicity in inflamed liver tissues. Although first clinical trials using TRAIL for the treatment

of various advanced cancers showed promising results, including stable disease, it becomes evident that TRAIL monotherapy most likely will not result in http://www.selleckchem.com/products/Deforolimus.html a sufficient response, especially in solid tumor entities.10 Under certain conditions, TRAIL treatment of solid tumors even increased tumor cell migration and metastatic spread.33,34 In such conditions, TRAIL might activate prosurvival pathways, such as the nuclear factor kappa B (NF-κB) or MAPK pathways, rather than induce apoptosis. Thus, restoring TRAIL sensitivity toward apoptosis by the combined treatment of TRAIL with TRAIL-sensitizing agents

is required to increase not only the clinical benefit, but, possibly, also to prevent cancer patients from harming effects of TRAIL in apoptosis-resistant tumors. In HCC high levels of various antiapoptotic

regulators of the death receptor and mitochondrial pathways, including cellular FLICE inhibitory protein (c-FLIP), X-linked inhibitor of apoptosis protein (XIAP), and several Bcl-2 proteins, have been observed.35,36 Proteasome inhibitors, such as BZB, have been recently shown to sensitize tumor cells, including HCC cells, toward TRAIL-induced apoptosis.23,24 These agents might be superior to other TRAIL-synergizing drugs, because inhibition of the proteasome as the central regulator of protein turnover affects multiple pathways and thus increases the likelihood that various TRAIL-resistance mechanisms can be bypassed.37 BZB treatment MCE of hepatoma cells resulted in TRAIL-R1/2 up-regulation, enhanced death-inducing signaling complex formation, and down-regulation of c-FLIP and XIAP.24 BZB not only influences the extrinsic, but also the intrinsic pathway by triggering the release of proapoptotic mitochondrial factors.24,38 In addition, proteasome inhibitors trigger cell-cycle arrest and NF-κB inhibition, thereby influencing apoptosis induction.39 In view of the various targets of proteasome inhibitors that have been identified, it must be noted that it was not our intention to further investigate the mechanisms of BZB-mediated TRAIL sensitization. Targeting of TRAIL to the tumor site represents an additional therapeutic strategy to increase antitumoral efficacy and avoid systemic toxicity.

Moreover, long-term studies of dieting indicate that the majority of individuals who dieted regain virtually all of the weight that was lost after dieting, regardless of whether they maintain their diet or exercise program.[8-10] Therefore, the maintenance of weight loss is still one of the biggest challenges of dietary interventions in patients with NAFLD. Provide 200–800 calories GDC-0941 in vitro per day, maintaining protein intake but limiting calories from both fat and carbohydrates. Must be undertaken with medical supervision to prevent adverse side-effects, such as loss

of lean muscle mass, increased risks of gout, gallbladder stone, and electrolyte imbalances. Aside from the possibility of achieving weight loss through caloric restriction (either low in carbohydrates or low in fats) as PLX4032 cell line a treatment for NAFLD, many dietary factors (especially macronutrients) can directly influence the development of NAFLD (Table 2).[3-7, 12-27] Manipulation of dietary composition might affect the outcomes of NAFLD and associated metabolic disorders independent of weight loss.[4-6] The dietary carbohydrates are often divided into complex carbohydrate (refer to any sort of digestible saccharide present in a whole food, where fiber, vitamins, and minerals are also found), or simple carbohydrates such as monosaccharides and disaccharides

(refer to sugar, provide calories but few other nutrients, and raise blood glucose rapidly especially if processed). Dietary carbohydrate

especially sugars contribute to increased circulating insulin and triglyceride concentrations and lead to increased hepatic de novo lipogenesis and decreased hepatic insulin sensitivity 上海皓元 because of the lipogenic potential of fructose during liver metabolism.[12-16] In addition, recent genome-wide studies have identified several polymorphisms that contribute to increased liver fat accumulation, with some of these genes relating to dietary carbohydrate and sugar consumption.[7, 33] Dietary fructose consumption primarily in the form of soft drinks worldwide has increased in parallel with the increase in obesity, diabetes, and NAFLD, and some studies have suggested a direct association.[1-6] The role of fructose and sucrose in NAFLD and metabolic disorders has been thoroughly reviewed elsewhere. Low-carbohydrate diets are increasingly employed for treatment of obesity and NAFLD; they have been shown to promote weight loss, decrease intrahepatic triglyceride content, and improve metabolic parameters of patients with obesity.[4-6, 9, 34] However, the relationship between long-term maintenance on low-carbohydrate diets and systemic insulin resistance in humans remains to be elucidated. In addition, low glycemic index (GI ≤ 55) foods such as oats have been shown to increase appetite, reduce calories intake, and decrease plasma glucose and total cholesterol levels.

4A), many cytokines PD0325901 cost and growth factors, including IL-6, IL-6 family cytokines (such as OSM, IL-11, cardiotrophin-1, ciliary neurotrophic factor, leukemia inhibitory factor), IL-22, epidermal growth factor, and hepatocyte growth factor, have been shown to stimulate STAT3 in the liver.16, 31-33 Here, we provided several lines of evidence suggesting that IL-6 is an important factor responsible

for the higher levels of pSTAT3 in the liver of STAT3 mice compared with wild-type mice. First, the basal levels of serum and hepatic IL-6 were higher in STAT3 mice than in wild-type mice, which is consistent with previous reports.27 Second, Kupffer cells from STAT3 mice produced much higher levels of IL-6 than wild-type Kupffer cells (200-500 pg/mL from buy HM781-36B STAT3 versus 10 pg/mL from wild-type mice) (Fig. 4C). Finally, blockage of IL-6 with a neutralizing antibody diminished

the basal levels of pSTAT3 in the liver of STAT3 mice (Fig. 4E). In addition, OSM also may contribute, to a lesser extent, to the enhanced pSTAT3 in the liver of STAT3 mice because Kupffer cells from these mice expressed higher levels of OSM compared with wild-type cells (Fig. 4D). It is believed that inflammation plays a key role in contributing to the progression of liver diseases1-6; however, many studies have reported that inflammation does not always correlate with hepatocellular damage in patients with chronic liver diseases.8-13 上海皓元医药股份有限公司 Based on the findings from this and other previous studies, we speculate that inflammation associated with a predominance of hepatoprotective cytokines such as IL-6, IL-6–related cytokines, and IL-22 may not correlate with hepatocellular damage, whereas inflammation with a predominant expression of Th1 cytokines (such as IFN-γ) may be closely associated with liver injury. Indeed, the downstream targets of IFN-γ, such as STAT1 and IP-10, have been shown to correlate with hepatocellular damage in patients with viral hepatitis C infection.34 Thus, understanding the effects of different types of liver inflammation on hepatocellular

damage may help us design better strategies to treat patients with chronic liver diseases. Additional Supporting Information may be found in the online version of this article. “
“Pathophysiological alterations in the endothelial phenotype result in endothelial dysfunction. Flow cessation, occurring during organ procurement for transplantation, triggers the endothelial dysfunction characteristic of ischemia/reperfusion injury, partly due to a reduction in the expression of the vasoprotective transcription factor Kruppel-like Factor 2 (KLF2). We aimed at (1) characterizing the effects of flow cessation and cold storage on hepatic endothelial phenotype, and (2) ascertaining if the consequences of cold stasis on the hepatic endothelium can be pharmacologically modulated, improving liver graft function.

“Clinical trials and animal models suggest that infusion of I-BET-762 purchase bone marrow cells (BMCs) is effective therapy for liver fibrosis,

but the underlying mechanisms are obscure, especially those associated with early effects of BMCs. Here, we analyzed the early impact of BMC infusion and identified the subsets of BMCs showing antifibrotic effects in mice with carbon tetrachloride–induced liver RG7204 mouse fibrosis. An interaction between BMCs and activated hepatic stellate cells (HSCs) was investigated using an in vitro coculturing system. Within 24 hours, infused BMCs were in close contact with activated HSCs, which was associated with reduced liver fibrosis, enhanced hepatic expression of interleukin (IL)-10, and expanded regulatory T cells

but decreased macrophage infiltration in the liver at 24 hours after BMC infusion. In contrast, IL-10–deficient (IL-10−/−) BMCs failed to reproduce these effects in fibrotic livers. Intriguingly, in isolated cells, CD11b+Gr1highF4/80− and CD11b+Gr1+F4/80+ BMCs expressed more IL-10 after coculturing with activated HSCs, leading to suppressed expression of collagen and α-smooth medchemexpress muscle actin in HSCs. Moreover, these effects were either enhanced or abrogated, respectively, when BMCs were cocultured with IL-6−/− and retinaldehyde dehydrogenase 1−/− HSCs. Similar to murine data, human BMCs expressed

more IL-10 after coculturing with human HSC lines (LX-2 or hTERT), and serum IL-10 levels were significantly elevated in patients with liver cirrhosis after autologous BMC infusion. Conclusion: Activated HSCs increase IL-10 expression in BMCs (CD11b+Gr1highF4/80− and CD11b+Gr1+F4/80+ cells), which in turn ameliorates liver fibrosis. Our findings could enhance the design of BMC therapy for liver fibrosis. (HEPATOLOGY 2012;56:1902–1912) For the past decade, clinical trials and experimental studies have suggested that infusion therapy of whole bone marrow cells (BMCs) has beneficial effects toward liver regeneration, injury, and fibrosis/cirrhosis by stimulating the proliferation of hepatocytes, increasing progenitor cells, and enhancing matrix degradation.1-3 However, the underlying mechanisms are unknown, in part because whole BMCs contain a wide range of cell types, including several types of stem and precursor cells of monocytic and granulocytic lineages.4 Events associated with hepatic fibrosis are well characterized, notably the excessive production of extracellular matrix (ECM) by activated hepatic stellate cells (HSCs).
