Hyaluronan 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 کاملThree-dimensional structure of the mammalian limbal stem cell niche.
Although the existence of the limbal stem cell (LSC) niche is accepted, precise knowledge of its three-dimensional (3D) architecture remains incomplete. The LSC niche was explored on freshly excised and organ-cultured corneoscleral rims from human donors (n = 47), pigs (n = 15) and mice (n = 27) with full-field optical coherence microscopy (FFOCM). Limbal crypt features were detected in 90% of ...
متن کاملLong-term Outcome of Limbal Stem Cell Transplantation for the Management of Total Limbal Stem Cell Deficiency due to a Chemical Burn
Purpose: To evaluate the long-term outcome of limbal stem cell transplantation (LSCT) for the management of total limbal stem cell deficiency (LSCD) due to chemical burn in Labbafinejad Medical Center (LMC). Methods: Records of patients with a history of severe (i.e. grade III and IV) chemical burns, who were referred to LMC and underwent LSCT, were reviewed and data including demographic chara...
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 کاملLimbal stem-cell transplantation.
Cornea epithelium is subject to constant trauma and shedding of the surface epithelium, and replenishment is from epithelial cells beneath and peripheral to the central desquamating epithelium. The origin of the corneal epithelium appears to reside in the crypts of Vogt, where a population of "immortal" stem cells resides, possessing enormous potential for clonogenic cell division. These cells,...
