Treatment of the human marrow mesenchymal stem cell culture with varying concentrations of Lithium and SB216763. A. Graph indicating that 5 mM Lithium is associated with a significantly higher density of viable cells. * indicates a significant difference, p<0.05. B. Graph indicating that treatment of the culture with 1 µM SB216763 resulted in a relatively higher density of viable cells. * indicates a significant difference, p<0.05.
