Objective: To isolate and identify human amnion mesenchymal stem cells( hAMSCs) from human placenta tissue. Methods: The cesarean full-term fetal placenta was collected,and human amnion mesenchymal stem cells were isolated with tissue adherent method and subcultured. The morphology of P1 ~ P3 generation cells was observed,flow cytometry was employed to detect positive molecular CD73-APC,CD90-FITC,CD44-PE,CD105-Cy5. 5 and negative molecular CD11b-PE,CD19-PE,CD34-PE、CD45-PE,HLA-DR-PE on the surface of the cel...
