HA-collagen nanofibers promoted macrophage elongation in vitro. Representative macrophage shapes on collagen and HA-collagen nanofibrous films under Alexa Flour™ 488 phalloidin staining (A) and SEM (B). Red arrows indicate round, pancake-like shape macrophage, white arrows indicate elongated macrophage. Scale bars: (A) 20 μm; (B) 10 μm. Quantitative analysis of macrophage elongation based on images of Alexa Flour™ 488 phalloidin staining (C) and SEM (D). n = 3, ***p < 0.001
