Abstract:
0.05) . No significant differences were observed between the expansion folds of hNSC derived from various fetal brain samples when cultured under the same conditions. LIF played great roles on cell proliferation,in LIF + groups, hNSC cell number increased ranging from 4 000-8 400 folds, no cell differentiation occurred; and in LIF" groups,only 43 to 96 folds.The differentiation phenomenons were watched when cultured more than two months. In the course of cell culturing, observed that the effects of LIF on hNSC expansion were obviously demonstrated 50-60 days after inoculation.The number of neurons and astrocytes differentiated from the cultured hNSC were respectively identified by means of Immuno-cytochemical fluorescent assay, and the percentages of neurons(as a proportion of neuron and astrocyte number) were calculated,which were ranging from 12% to 83% in LIF+ cultures, significantly higher than 8% to 23% in LIF- ones(P
