Limbal 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,...
متن کاملLimbal Stem Cell Deficiency and Treatment with Stem Cell Transplantation
The cornea is the outermost tissue of the eye and it must be transparent for the maintenance of good visual function. The superficial epithelium of the cornea, which is renewed continuously by corneal stem cells, plays a critical role in the permanence of this transparency. These stem cells are localized at the cornea-conjunctival transition zone, referred to as the limbus. When this zone is af...
متن کاملAllo-limbal transplantation in patients with limbal stem cell deficiency.
AIM To report the outcome of a series of patients with stem cell deficiency who underwent allo-limbal transplantation and to describe a technique for this procedure. METHODS Six consecutive patients underwent allo-limbal stem cell transplantation. The primary diagnosis included alkali burn (n = 2), trachoma (n = 1), chronic rosacea blepharitis and kerato-conjunctivitis (n = 1), aniridia (n = ...
متن کاملLimbal stem cell transplantation: current perspectives
Regeneration of the corneal surface after an epithelial insult involves division, migration, and maturation of a specialized group of stem cells located in the limbus. Several insults, both intrinsic and extrinsic, can precipitate destruction of the delicate microenvironment of these cells, resulting in limbal stem cell deficiency (LSCD). In such cases, reepithelialization fails and conjunctiva...
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...
