Objective: To observe the differentiation of bone marrow stem cells in rat hepatic fibrogenesis environment into hepatocytes.
Methods: Rat hepatic fibrosis was induced by subcutaneous injection of CCl4. Bone marrow stem cells with Thy positive, CD3 and CD45RA negative were enriched from the bone marrow by fluorescence-activated cell sorting. The bone marrow stem cells were labeled with PKH26-GL, and then autotransplanted. After six weeks, albumin, ck8 and a-smooth muscle actin expression were determined by immunocytochemistry.
Results: The PKH26-GL labeled cells expressed albumin and ck8, but did not express a-smooth muscle actin in hepatic fibrogenesis environment.
Conclusion: Bone marrow stem cells in hepatic fibrogenesis environment can differentiate into hepatocytes, but can't differentiate into myofibroblasts
