Figure 5 : Hypertrophic phenotype expression by SF-CPs.

Collagen type X (CollX) mRNA expression (A), and alkaline phosphatase (ALP) activity (B), by SF-CPs after 10 and 20 days in chondrogenic pellet culture, supplemented with TGF-β1 or BMP-2. There were no significant changes in Coll X expression or ALP activity (ANOVAs, n=5; p<0.05). Reference values for equine articular chondrocyte (AC) pellets (n=4; black bars) and bone marrow-derived MSCs (n=4; white bars) are also shown.
