Maintaining corneal health and transparency are necessary pre-requisites for exquisite vision a function ascribed to stem cells SCs nestled within. This paved the way for limbal stem cell transplantation as a means of surgically addressing limbal stem cell deficiency LSCD.

Patients with limbal stem cell deficiency face a life of blindness.
. Damage to the limbus can lead to limbal stem cell deficiency LSCD. Limbal stem cell deficiency syndrome means there is no longer a source for corneal epithelial cells. In this article Di Girolamo and colleagues characterized plasticity of ocular surface epithelia using a clinically relevant mouse model of limbal stem cell deficiency. 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.
Limbal stem cell deficiency syndrome means there is no longer a source for corneal epithelial cells. These new collagens produced by conjunctival fibroblasts may represent an attempt to replace the loss of limbal stem cells. In addition to LSC this niche. Our findings therefore support the hypothesis that an epithelial.
To evaluate the clinical and visual outcomes of fluid-filled scleral lens devices SL wear in patients with limbal stem cell deficiency LSCD. We are developing a stem cell-based drug which could potentially restore sight. Although limbal stem cell deficiency LSCD is a rare condition this really is an umbrella term that we use to describe a heterogeneous group of diseases said Christine. LSCD is an ocular surface disease caused by a decrease in the.
This is replaced by conjunctival epithelial that normally surrounds the cornea and in. This may be primary - related to an insufficient stromal microenvironment to support stem cell functions such as. They show three types of. Direct damage to LSCs andor the destruction of their niche microenvironment leads to limbal stem cell deficiency LSCD.
Defects in renewal and repair of ocular surface as a result of limbal stem cell deficiency are now known to cause varying ocular surface morbidity including persistent photophobia repeated. Limbal stem cells LSCs are crucial for the. The concept that the corneoscleral limbus is the repository of cells essential for renewal of corneal epithelium was first elucidated in the 1970s and 1980s1 2 3 The. Characteristics of limbal stem cells include a slow turnover rate therefore retain DNA labels for long time periods high proliferative potential in the event of injury.
This is replaced by conjunctival epithelial that normally surrounds the cornea and in. As a result the barrier function of the limbus is. By definition the term limbal stem cell deficiency implies that this condition results from a reduction in the number of limbal stem cells present for corneal epithelial.
