Rhodamine-phalloidin staining and immunofluorescence of alkaline phosphatase (ALP) and osteocalcin (OC) in 2D-cultured hADSCs for 4 weeks with (a–c) proliferation medium or with (d–f) commercial MesenCult or (g–i) BMP2-supplemented osteogenic differentiation media. Cell nuclei were stained with DAPI and observed in blue, the distribution of actin filaments in red, and the presence of ALK or OC in green. Scale .
