A Human Corneal Epithelial Cell Line Model for Limbal Stem Cell Biology and Limbal Immunobiology
: Limbal stem cell (LSC) deficiency is a visually debilitating condition caused by abnormal maintenance of LSCs. It is treated by transplantation of donor-derived limbal epithelial cells (LECs), the success of which depends on the presence and quality of LSCs within the transplant. Understanding the immunobiological responses of these cells within the transplants could improve cell engraftment ...
متن کاملHyaluronan Rich Microenvironment in the Limbal Stem Cell Niche Regulates Limbal Stem Cell Differentiation
Purpose Limbal epithelial stem cells (LSCs), located in the basal layer of the corneal epithelium in the corneal limbus, are vital for maintaining the corneal epithelium. LSCs have a high capacity of self-renewal with increased potential for error-free proliferation and poor differentiation. To date, limited research has focused on unveiling the composition of the limbal stem cell niche, and, m...
متن کاملLimbal epithelial crypts: a novel anatomical structure and a putative limbal stem cell niche.
BACKGROUND/AIMS There is substantial evidence that mammalian epithelial stem cells are located within well defined niches. Although the corneoscleral limbus is acknowledged as the site of corneal epithelial stem cells no anatomical niche for such cells has yet been described. The authors undertook to re-evaluate the microanatomy of the limbus in order to identify possible sites that may represe...
متن کاملCorneal development, limbal stem cell function, and corneal epithelial cell migration in the Pax6(+/-) mouse.
PURPOSE To investigate the etiology of corneal dysfunction in the Pax6(+/-) mouse model of aniridia-related keratopathy. METHODS Mosaic patterns of X-gal staining were compared in the corneal and limbal epithelia of female Pax6(+/-) and Pax6(+/+) littermates, age 3 to 28 weeks, hemizygous for an X-linked LacZ transgene, and Pax6(+/+), LacZ(-)<-->Pax6(+/+), LacZ(+) and Pax6(+/+), LacZ(-)<-->Pa...
متن کاملComparison of Ultra Structure and Gene Expression of Cultured Limbal Stem Cells and Fresh Conjunctival, Limbal and Corneal Tissues
Purpose: The present study intends to show the characteristics of cultured limbal stem cell (CLSCs) and to compare them with normal Conjunctival (C), Limbal (L) and Cornea (K) tissues. Materials and Methods: The expressions of a set of genes potentially involved in differentiation and stemness function of limbal stem cells were assessed in freshly prepared limbal, corneal, and conjunctival tis...
