Fig. 1From: The effects of human umbilical cord-derived mesenchymal stem cell transplantation on endometrial receptivity are associated with Th1/Th2 balance change and uNK cell expression of uterine in autoimmune premature ovarian failure miceCell phenotype and differentiation characterization in hUMSCs. Cell phenotype was characterized with specific surface markers using flow cytometry analysis. Cell differentiation was confirmed by cellular staining. a Blue histograms represent isotype control staining, and red histograms represent the expression of specific cell surface markers. b–d Cells were cultured under conditions to differentiate into osteoblast or adipogenesis cells. b The fibroblast-like morphology of primary hUMSCs. c Osteoblasts with alizarin red staining; positive staining was shown brown color with calcium deposition (× 400). d Adipogenic cells with the accumulation of neutral lipid vacuoles which are stained with Oil Red O (× 400). hUMSC human umbilical cord-derived mesenchymal stem cellsBack to article page
