New technique for regenerating corneal stem cells, would allow these patients regain their vision.
Patients who have their corneas damaged by disease or injury and may lose sight could regain their eyesight thanks to a new technique developed by scientists to regenerate the stem cell membrane.
The British journal Nature published the results Thursday of a U.S. investigation that discovered a molecular "trick" that allows "repair the limbus, which is an essential part of the cornea for vision."
Keyed trace molecules (ABCB5 antibodies), scientists were able to "hunt the elusive stem cells of human eyes, able to regenerate and repair, and transplanted into mice, which developed anatomically normal corneas and functional."
"This procedure could help restore the sight of victims of burns and chemical injuries, and patients with diseases that damage the eye," the study authors said.
Stem cells from the limbus (LSC) reside in the basal limbal epithelium of the eye, or limbo, and help maintain and regenerate the corneal tissue, which are essential for healthy vision, but without them the cornea will return cloudy and disrupt vision.
A deficiency of these cells due to disease or injury to the eye is one of the most common reasons behind blindness worldwide.
