Abstract
The regenerated epithelium derived from limbal epithelium was histologically and biochemically compared with epithelia regenerated from corneal and bulbar conjunctival epithelia. Regenerated epithelium of limbal origin increased in thickness with time after healing and showed no goblet cell appearance on the cornea. Apparently regenerated epithelium from the limbus is more like regenerated epithelium of corneal origin than that of bulbar conjunctival origin. The glycogen content and protein pattern profile showed that regenerated epithelium of limbal origin had characteristics intermediate between those of corneal and bulbar conjunctival origin. Apparently there are 3 distinct types of ocular surface epithelia corneal, bulbar conjunctival and limbal, and limbal epithelium may behave differently from corneal and conjunctival epithelia in ocular surface wound healing.
