Effects of fetal bovine serum on differentiation of human fetal neural stem cells in vitro / 第三军医大学学报

ABSTRACT

Objective To observe the effects of fetal bovine serum(FBS) on differentiation of human neural stem cells (NSCs). Methods The effects of FBS with different concentrations on differentiation of human fetal NSCs were observed by cell culture, immunocytochemistry and flow cytometry. Results Human fetal NSCs could be induced to differentiate mainly three types of nerve system cells(neuron, astrocyte and oligodentrocyte). There were 80%～90% astrocytes of differentiated cells from human fetal NSCs with the concentration of 15% FBS induced. Conclusion Concentration dependent FBS in culture medium may have effect on the ratio of neurons to glial cells differentiated from human NSCs in vitro .
