Figure 3From: Effect of parathyroid hormone on early chondrogenic differentiation from mesenchymal stem cellsEffect of PTH on collagen expression in chondrogenic pellet culture for 3, 7, and 21 days. Relative mRNA levels of Col2a1 (A), Col10a1 (B), and Col1a1 (C) following PTH treatment are compared with expression in the control (0 nM PTH) (n = 8 for each dose). *P < 0.05 vs. control group (Steel's test).Back to article page
