(A) Representative nucleus/cytoskeleton staining images of RAW 264.7 cells grown on different PVP/PVA-ALN, PVP/PVA-HA and PVP/PVA-ALN-HA nanofiber composite scaffolds whereas cytoskeleton and cell nuclei were stained by Phalloidin (green) and DAPI (blue), respectively (red arrows represent the formed osteoclasts); (B) Enzyme activity of TRAP from RAW 264.7 cells cultured on different scaffolds. p-value < 0.05 and 0.01 were denoted by * and **, respectively.
