Figure 6
Transmission electron microscopy images showing (a) The basal limbal stem cells (LESCs), and (b, c) The limbal stromal epithelial stem cells clusters presented two types of cells, putative stem cells (SC) large cells characterized by high nuclear to cytoplasmic ratio with a large, indented nucleus, and populations of the transit-amplifying epithelial cells (TA)(arrow) small basal cuboidal cells hold a large nucleus with a prominent nucleolus. The limbal stromal epithelial stem cells cluster was enclosed by telocytes (TC) with long telopods (arrowhead). (d) The telocytes (TC) contain an indented oval nucleus bounded by a thin layer of cytoplasm and have long telepods (Tp) packed with rER.
