Phenotypic and functional characterization of hAMSCs. (A) Representative micrographs of hAMSCs from passage 0 to 3 (no staining, 100 ×). (B) Multilineage differentiation ability of hAMSCs. Adipogenic differentiation of hAMSCs (left) were stained with Oil Red-O, and osteoblastic differentiation of hAMSCs (right) were stained with Alizarin Red (staining, 100 ×). (C) Flow cytometric analysis indicating hAMSCs positive for CD90, CD105 and CD73 while negative for CD34, CD45, CD11b and HLA-DR
