Collagen deposition in cultured corneal cells. hCSSC cultured on patterned silk substrata without RGD modification (a,b,c), or with RGD modification (d,e,f), and hCF on RGD-modified substrata (g,h,i) after 9 wks, were immunostained for collagens as described under Methods. Collagen I, (a,d,g)); collagen V (b,e,h); and collagen VI(c, f, i). Nuclei were stained by DAPI (blue).
