Growing limbal stem cells without using a human scaffold

The Hindu  

Corneal cells are destroyed or worn out every day. Restoring sight in the damaged eye is done by transplanting the limbal stem cells from the healthy eye to the damaged eye. Since removal of large amounts of limbal stem cells from the undamaged eye may lead to depletion of stem cells, doctors usually remove a small quantity of limbal stem cells from the healthy eye and expand them in the laboratory by culturing. One eye of all the rabbits was damaged and limbal stem cells from the other eye were taken and expanded on the polymer scaffold. “So we put a restraint on the eye of others and thereafter everything went well.” According to him, the quantity of undifferentiated stem cells is more when the polymer scaffold was used.

World's first stem cell treatment restores vision, offers new hope to the blind

India Today  

A recent Lancet study has revealed that stem-cell transplants using reprogrammed stem cells have brought significant, lasting improvements in vision for people with severely damaged corneas. These patients received corneal cell transplants derived from induced pluripotent stem cells, a cutting-edge approach that appears to offer hope for those with this challenging condition. Three of the four patients experienced major, sustained …

london, May 30 In a first, British scientists have 3D printed human corneas that could cut down shortage of eye donors available for transplant. In the research, researchers from Britain's Newcastle University, mixed stem cells from a healthy donor cornea with alginate and collagen to create a solution that could be printed or a "bio-ink". "Our unique gel -- a …
