COL2A1 and COLXA1 mRNA expression levels in HAC and BMSC chondrogenic pellet cultures. (A) Pellets from HAC and BMSC were cultured in chondrogenic media for 7 and 14 days; and COL2A1 mRNA levels were determined. Additionally, 14 day pellets whose media was supplemented with BMP7 were also examined. Day 0 refers to cell monolayers before pellet culture. *p<0.05 versus day 0 (one-way ANOVA with Dunnett's post hoc test). Note from the y-axis scales that the difference in COL2A1 expression levels was cultured in chondrogenic media with and without BMP7 for 14 days and COLXA1 between the HAC and the BMSC cultures (B) Pellets from HAC and BMSC mRNA levels determined. *p<0.05 effect of BMP7 supplementation (unpaired students t-test). Data are presented as mean and standard deviation of arbitrary 2−Ct relative expression values measured in three donors. TGFβ-1, transforming growth factor β-1; GAPDH, glyceraldehyde-3-phosphate dehydrogenase.
