Evaluation of the biocompatibility of the decellularized FS. (a) FDA/PI staining of BMSCs cultured on the ridge and spike regions of decellularized FS. Scale bar was 500 μm (b) The cell viability of BMSCs cultured on a cell culture plate (CCP) or decellularized FS for 48 h. (c) The cell growth of BMSCs cultured on CCP or FS. (d, e) SEM images and phalloidin staining of BMSCs cultured on the ridge and spike regions of decellularized FS. Scale bar was 100 μm
