FIG. 4.
Real-time reverse transcription–polymerase chain reaction analysis of chondrogenic gene expression in hBMSC-laden agarose or mGL hydrogels at day 90 (*p<0.05, **p<0.01). Genes analyzed include Sox 9, collagen type II, and aggrecan. hBMSCs cultured on tissue culture plastic without chondrogenic induction served as control. All values are normalized to control.
