Cell morphology on the different scaffolds after two weeks culture.
Fluorescence microscopy image of periodontal ligament fibroblasts A) on RADA16, B) on PRG, C) on PDS and D) on rat type I Collagen as a positive control. Fluorescenct staining with Rhodamin phalloidin for F-actin (red) and SYTOX Green for nuclei (green) showed the cell attachments and distributions. The scale bar represents 100um for all images.
