Fig. 2From: Design and evaluation of nano-hydroxyapatite/poly(vinyl alcohol) hydrogels coated with poly(lactic-co-glycolic acid)/nano-hydroxyapatite/poly(vinyl alcohol) scaffolds for cartilage repairThe results of cellular adhesion ability (a). The results of cellular proliferation by MTT (b). HE staining and immunohistochemical staining of type II collagen (c) after co-culturing rabbit chondrocytes with scaffolds for 3 days, 7 days, 14 days; PVA mass fraction of 5 wt% (E1), 10 wt% (E2), or 15 wt% (E3); PLGA of 30 wt%; and nano-HA of 5 wt% were used for investigation. The control group contained HA: 5 wt%, PVA: 165 wt% (CG)Back to article page
