GelMA–MWCNTs/Co hydrogel on HIF-1α and VEGF expression. (A) Protein expression of HIF-1α in cocultured SCAP and HUVECs after growing in GelMA and GelMA–MWCNTs/Co hydrogel for 24, 48, and 72 h, determined by Western blot. (B) VEGF secretion levels from cocultured SCAP and HUVECs at different time intervals. (C) Gene expression levels of VEGF in cocultured cells at different time points. (∗p < 0.05, ∗∗p < 0.01. ∗∗∗p < 0.001, n = 3)
