Figure 4From: Effect of parathyroid hormone on early chondrogenic differentiation from mesenchymal stem cellsEffect of PTH on transcription factor involved in chondrogenic differentiation and response of PTH receptor. In chondrogenic pellet culture for 3, 7, and 21 days. Relative mRNA levels of Sox9 (A) and PTH1R (B) 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
