- This study was designed to compare re-epithelization rate/feature of conjunctival epithelial cell on amniotic membrane and anatomical difference between normal amniotic membrane and de-epithelial amniotic membrane. Human conjunctival tissue obtained while cataract operation were used in this study. Primary cultured human conjunctival epithelial cell and fibroblast were incubated on intact amniotic membrane and de-epithelialized amniotic membrane. After incubation for 3, 5 and 7 days, re-epithelization rate was analyzed using cell tracker and microscopic feature was examined using methylene blue and hema-toxylin-eosin stain. For cell marker analysis, cytokeratin 14 and vimentin antibody immunofluorescence stain were used. Clearance rate of epithelial cells on amniotic membrane using trypsin was better than using 25% alcohol. The results of re-epithelization rate using cell tracker, HaCaT, conjunctival firbroblast, and epithelial cell were rapidly incubated on de-epithelialized amniotic membrane. Wound healing and re-epithelization were more rapidly induced on de-epithelialized amniotic membrane on permanent amniotic membrane graft.
