Immunocytochemistry (ICC) of Integrin β1 from hWJ-MSCs grown on silk fibroin-spidroin mix scaffold (SF 90% + SS 10%) and silk fibroin scaffold (SF 100%) observed under confocal microscope 6, 24, and 48 h post seeding. Integrin β1 appeared red on the images. Yellow arrows indicate the cell nuclei. SF = silk fibroin; SS = silk spidroin.
