Expression of specific genes and in vivo chondrogenic capacity of LP1 and HP3. a Gene expression profiles of LP1 (5 × 105 cells/ml) and HP3 (2 × 106 cells/ml) OA chondrocytes in type I collagen scaffolds (n = 3 in each group). b Histological analysis of scaffolds. Scale bar = 1 mm. c Bern score evaluation (n = 3 in each group). *p < 0.05, **p < 0.01, and ***p < 0.001; data are mean ± standard. LP1, low-density P1 in type I collagen scaffolds; HP3, high-density P3 chondrocytes in type I collagen scaffolds
