Romidepsin Promotes Osteogenic and Adipocytic Differentiation of Human Mesenchymal Stem Cells through Inhibition of Histondeacetylase Activity

Figure 3

Effect of romidepsin treatment on the differentiation of human bone marrow stromal stem cells (hMSCs) into osteoblasts. hMSCs were induced to osteoblastic differentiation in the presence of romidepsin (5 nM) or vehicle control for 24 h. The effects on osteoblastic differentiation were examined at day 10. (a) ALP staining for romidepsin-treated compared to vehicle-treated control cells (4x magnification) using an EVOS cell imaging system. (b and c) Representative images of ALP staining from (a); (d) quantification of ALP activity; (e) validation of quantification of ALP activity in romidepsin-treated versus vehicle-treated control cells in primary hMSCs. Data are presented as mean ± SEM from two independent experiments, , , and .
