Isolation and differentiation of stem cells derived from human placenta into cardiomyocytes / 中国病理生理杂志

ABSTRACT

AIM: To isolate the stem cells from human placenta and induce them into cardiomyocytes. METHODS: Stem cells were isolated from human placenta and characterized by morphologic analysis. The “hanging drop” methods were used to inducte stem cells into cardiomyocytes. The expressions of atrial natriuretic factor(Anf) and ?-myosin heavy chain(?-MHC) genes were analyzed by RT-PCR. RESULTS: Stem cells derived from human placenta were self-renewed and differentiated into cardiomyocytes in vitro. RT-PCR showed that Anf and ?-MHC genes were expressed in the “beating cells”.CONCLUSION: Human placenta is an abundant source of stem cells.
