Fig. 5.
Expression of ostoblast genes in a representative sample of cultured first-passage human marrow-derived stromal cells. Results of real-time polymerase chain reactions were analyzed as described in the legend to Figure 3. While dexamethasone (Dex) treatment increased levels of alkaline phosphatase (AP) mRNA at both day 6 and day 10, BMP treatment did not. Bone sialoprotein (BSP) mRNA was increased by either dexamethasone or BMP, and osteocalcin mRNA was unaffected by either dexamethasone or BMP.
