Characteristics of hucMSCs. a, b Cell morphology of passage 0 (bar = 50 μm) and passage 3 (bar = 200 μm) human umbilical cord mesenchymal stem cells (hucMSCs) observed under an inverted microscope (bar = 50 μm). c, d Osteogenic differentiation of hucMSCs was performed in the differentiation medium, while the control cells were grown in a regular medium. Both of them were dyed with Alizarin Red S staining. Most hucMSCs were Alizarin red positive. e, f Oil red O staining was used to stain hucMSCs after adipogenic differentiation, showing the Oil red O-positive lipid droplets. g Flow cytometry analysis of the phenotypic markers of hucMSCs showed that hucMSCs were positive for CD90, CD44, CD105, CD73, and CD105 and negative for CD34, CD45, CD11b, CD19, and human leukocyte antigen (HLA)-DR
