| Research Abstract |
There are two types of stem cells, hematopoietic stem cells(HSC) and mesenchymal stem cells(MSC), present in bone marrow(BM). While HSC have been well characterized and applied for BM transplantation, little is known about the physiological roles of MSC. In this study, we have revealed that hematopoietic cells derived from HSC migrate into fibrotic liver and contribute the regression of fibrosis by expressing collagenases. In contrast, MSC or its derivatives are not mobilized from BM into fibrotic liver tissue during hepatic fibrogenesis.
