Quantitative analysis of cartilage-specific genes (COL2A1, SOX9 and ACAN) and hypertrophic chondrocyte gene (COL10A1) expressions in the chondrocyte pellet derived from three MSC sources. The BM- MSCs showed significantly higher expressions of COL2A1, SOX9 and ACAN expression with less hypertrophic differentiation (COL10A1), collectively the results in Figs 4 and 5 indicate that BM- MSCs have the best chondrogenic potential.
