Figure 2

Bone-marrow-derived mesenchymal stem cells (BMSCs) cultured on GMs. Optical microscope images of BMSCs-GM on (A) Day 3 and (B) Day 7. White arrows were showing the bridging of adjacent GMs by elongated BMSCs, indicating cell–cell and cell–microsphere interactions. (C) SEM (3000× Magnification; scale bar: 40 µm) and (D) Confocal Laser Scanning Microscopy (CLSM) images of BMSCs-GM on Day 7. For the CLSM image, cell actin was stained with phalloidin-TRITC and nucleus with Hoechst. (A,B,D: 100× Magnification; scale bar: 100 µm).
