media (*, p<0.001 compared to hMSC; +, p <0.001 compared to TGFβ treated hMSC; ◆, p = 0.0038 compared to JC; x, p = 0.045 compared to hMSC). In chondrogenic media, BCP and JC pellets produce more proteoglycan compared to hMSC in the presence or absence of TGFβ as assessed by DMMB, N=8 (A), a result that is consistent with Aggrecan IHC N≥3 (B). JC pellets showed increased expression of chondrogenic genes relative to BCPs and hMSC+TGFβ pellets. hMSC+TGFβ pellets had greater expression of hypertrophic genes than BCP pellets N=5 (C).
