Figure 3. Relative gene expression of chondrogenic and collagen genes at 2 weeks.

Figure 3.

Relative gene expression of sox9, the master transcription factor involved in chondrogenesis, was upregulated in the Col I/II hydrogels and pellets with TGF-β3 (Pel) compared to either the Col I hydrogels or pellets without TGF-β3 (Pel (-TGF)). An ANOVA and Tukey’s post hoc tests were performed (p < 0.05) for gene expression analysis of sox9, aggrecan, collagen type I, and collagen type X (n=4). An ANOVA and a Games Howell post hoc test were performed (p < 0.05) for gene expression analysis of collagen type II. The * indicates statistical difference from the pellets without TGF-β3 (Pel (-TGF)), and the # indicates statistical difference from the Col I hydrogels.
