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

Figure 4

Microarray gene expression profiling of osteoblast-differentiated human bone marrow stromal stem cells (hMSCs) following romidepsin treatment. (a) Heat map and unsupervised hierarchical clustering were performed on differentially expressed genes induced by romidepsin compared to those of vehicle-treated control hMSCs at day 10 after osteoblastic differentiation; (b) Pie chart illustrating the distribution of the top 15 enriched pathway categories in the differentially expressed genes identified in romidepsin-treated hMSCs; (c) validation of the selected gene panel during osteoblastic differentiation using qRT-PCR. Gene expression was normalized to β-actin; (d) quantification of ALP activity in hMSCs induced to osteoblastic differentiation for 10 days after treatment with romidepsin in the absence or presence of a FAK inhibitor (PF-573228, 5 μM) or TGFβ inhibitor (SB505124, 5 μM). Data are presented as mean ± SEM, ; , , and .
