Figure 4.

qRT-PCR analysis of MSC pellet cultures treated with NCCM or TGFβ. Expression of genes associated with chondrocyte or NP phenotypes were measured. Data were averaged over three patients, normalized to GAPDH and expressed relative to CM values (average +/- SEM). * indicates significantly greater collagen III expression in NCCM relative to TGFβ medium (P < 0.05).
