Abstract

BACKGROUND: Cultures from multiple portions of umbilical cord blood mesenchymal stem cells have been shown to undergo more rapid proliferation and attachment than single portions. OBJECTIVE: To observe growth of basic fibroblast growth factor (bFGF)-induced cultures of human amnion-derived mesenchymal stem cells (AMSCs) and differentiation into neuronal-like cells. DESIGN, TIME AND SETTING: Comparative observation. The study was performed at the Laboratory of Microbiology and Immunology, Basic Medical School of Zhengzhou University from January to May 2008. METHODS: Amnia from full-term, uterine-incision delivery were donated by 12 healthy women. AMSCs were obtained by cell separation and culture techniques, and were passaged and induced by bFGF. From the third passage, a total of 1 mL AMSCs, at a density of 1.0 × 104/mL, was separately harvested from six samples, which served as group A. A total of 1 mL AMSCs, at a density of 1.0 × 104/mL, was harvested separately from the remaining six samples, which served as group B. A total of 0.5 mL from the six samples of group A and 0.5 mL from the six samples of group B were combined to form group C. MAIN OUTCOME MEASURES: Differences in cell quantity among the three groups were compared by cell quantification and 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) analysis. Expression of a glial cell marker, neuron-specific enolase, and nestin was detected in the three groups by immunocytochemistry. RESULTS: Cell quantification and MTT analysis of live cells, as well as AMSC absorbance, were significantly greater in group C compared with groups A and B at 18 days of culture (P < 0.05), and no significant difference was observed between groups A and B. Glial fibrillary acidic protein, neuron-specific enolase, and nestin were expressed in all groups following bFGF induction. CONCLUSION: Mixed AMSC cultures promoted proliferation, and bFGF-induced AMSCs differentiated into neuronal-like cells.
