Human limbus: "Limbal epithelial stem cells reside in the basal layer of the epithelium (Ep), which undulates at the limbus. Daughter transient amplifying cells (TACs) divide and migrate towards the central cornea (arrowed) to replenish the epithelium, which rests on Bowman's layer (BL). The stroma (St) of the limbal epithelial stem cell niche is populated with fibroblasts and melanocytes and also has a blood supply." "At the corneo-scleral junction in an area known as the limbus, there is a population of limbal epithelial stem cells (LESCs). LESCs share common features with other adult somatic stem cells including small size (Romano et al., 2003) and high nuclear to cytoplasmic ratio (Barrandon and Green, 1987). They also lack expression of differentiation markers such as cytokeratins 3 and 12 (Kurpakus et al., 1990; Schermer et al., 1986)."
"Limbal stem cells (LSC) represent a quiescent cell population with proliferative capacity residing in the basal epithelial
layer of the limbus within a cellular niche. "
