Characterization of human amniotic mesenchymal stem cells (hAMSCs). (a) Primary passage (P0) of hAMSCs. (b–e) Negative controls in eac h flow cytometric histogram. Human AMSCs were positive for CD105 (b), CD29 (b) and CD90 (c), and negative for CD34 (d) and HLA-DR (e). (f) hAMSCs at personal passage three (P3). (G-I) hAMSCs induced by osteogenic (g), adipogenic (h), and chondrogenic (i) media were stained by Alizarin Red S, Oil Red O, and Toluidine Blue solution, respectively.
