An Update on Ocular Surface Epithelial Stem Cells: Cornea and Conjunctiva

Figure 2

Limbal SCs for the corneal epithelium reside in the basal layer of the limbal epithelium. Transient amplifying cells divide and migrate towards the central cornea to replace the terminal corneal ECs that get shed from the corneal surface. The stroma of the limbal SC niche is populated by fibroblasts and nourished by blood vessels (BL: Bowman’s layer).
