Evaluation of Silk Fibroin-RGD-Stem Cell Factor Scaffold Effect on Adhesion, Migration, and Proliferation of Stem Cells of Apical Papilla

Figure 7

Laser scanning confocal microscopy images of cells on scaffolds after 7 d seeding. Cell cytoskeletons were stained with Rhodamine Phalloidin (a1, b1, c1, d1). Cell nuclei were stained with Hoechst 33258 (a2, b2, c2, d2). Merged pictures of cell cytoskeletons and nuclei (a3, b3, c3, d3) (red arrows: cell cytoskeletons; yellow arrows: cell nuclei).
