Biological characteristics of human umbilical cord mesenchymal stem cells (hUCMSCs).

(A) Phase contrast images of passage 2 hUCMSCs. hUCMSCs can be differentiated into osteogenic (B; Alizarin red staining), adipogenic (C; Oil-red O staining) and chondrogenic lineages (D; Safranin O staining) following treatment with different culture media. Scale bars in A–D: 200 μm. (E) Flow cytometry showing that hUCMSCs are positive for CD29, CD44, CD90, CD105, CD71 and CD73, and negative for CD34 and CD45.
