FIG. 3.

Representative micrographs of fibroblast growth on scaffolds. (A, B) ESEM images of fibroblast cultured for 7 d on bare PLGC and hybrid scaffold, respectively. (C, D) ESEM images of fibroblast cultured for 28 d on bare PLGC and hybrid scaffold, respectively. The inter fiber space of bare scaffold appeared empty and the cells appeared to have grown along the fibers but the fibers of hybrid scaffold were connected by cell sheets. (E) Confocal image of scaffold after nuclear stain; color code indicates Z-depth of cells inside the hybrid scaffold after 7 d of fibroblast culture. (F) Light micrograph of 28-d-old construct with migratory fibroblasts; cell sprouting seen is 24 h after transfer into an empty dish. Scale bars: 300 μm (A, B); 200 μm (C, D); and 200 μm (F).
