Purmorphamine (10, 20 μM) in combination with sirolimus significantly decreases cell numbers according to the MTT assay. Purmorphamine induces up-regulation of alkaline phosphatase activity and expression of RUNX-2 at day 14. Up-regulation of osteocalcin is detected at the 3 and 5 μM doses of purmorphamine on day 14 post-induction. Matrix mineralization remains unchanged in the presence or absence of purmorphamine[1]. Purmorphamine induces STAT3 phosphorylation in mouse ES cell line ES14 and mesenchymal stem cell line C3H10T1/2[2]. Purmorphamine up-regulates the expressionof markers of the osteoblast phenotype-ALP activity and bone-like nodule formationd-in human bonemarrow mesenchymal cells[3].

Protocol
To determine non-toxic doses of the small molecules, 5×105 passaged-3 human MSCs are seeded in each well of a six-well culture plate and incubated in expansion medium (as mentioned above) at 37°Cand 5% CO2. Two days later, the medium is exchanged with osteogenic medium (OM) that consisted of α-MEM supplemented with 10% FBS, 10 nM dexamethasone, 50 μg/mL ascorbic acid 2-phosphate, and 10 mM beta-glycerol phosphate. This OM is supplemented with different concentrations of purmorphamine (1, 3, 5, 10, and 20 μM) and sirolimus (0.1, 1, 10, 100, and 200 nM). The cultures are maintained for an additional two days and then assessed for the presence of viable cells with the MTT assay, by the addition of MTT solution (5 mg/mL in PBS) to the medium at a ratio of 1:5. Cells are then incubated at 37°C and 5% CO2. Two hours later, the medium is removed and 500 μL of DMSO is added to the treated cells in order to dissolve the formazone precipitate. The optical absorption rate is read at 570 nm. Cell viability is calculated as percent value relative to the control group which is only treated with OM.
