RT-PCR analysis of chondrogenic and hypertrophic gene expression after 2 weeks of culture with various cell types and oxygen tensions. Collagen type II (A), type I (B), type II / I ratio (C) and collagen type X (D). Results are presented as mean ± SD with n = 4. The dashed line represents the AC stock used to seed the scaffolds. # and * denote statistically significant difference to the corresponding normoxic culture condition (same cell type) and AC group (same oxygen tension), respectively (p < 0.05).
