Figure 15. Representative images of human cartilage stem/progenitor cells (CSPCs) differentiated into (A) adipocytes, (B) osteoblasts, and (C) chondrocytes
at day 21 of culture, following staining with (A) Oil Red-O, (B) Alizarin Red, and (C) Alcian Blue. The black arrow indicates the differentiation of CSPCs
into a 3D cartilage construct. Scale bars: 100 µm (A and B).
Figure 16. The percentage survival of chondrocytes on scaffolds with different compositions (PEGDMA; PEGDMA/ODMA; PEGDMA/ODMA/CH)
at 24, 48, and 72 h (n = 3). Abbreviations: CH, collagen hydrolysate; ODMA, oligomers of dopamine methacrylate; PEGDMA, polyethylene glycol
dimethacrylate. **p < 0.01 and ***p < 0.001 were regarded as significant.
