Stem cells from umbilical cord may help in treating people with corneal opacity, say U.S. researchers.
Cornea - the transparent front part of the eye that protects the delicate internal structures, helps to focus light and produce an image. However, disease or damage to the cornea may lead to its turbidity, which, in turn, reduces visual acuity. Corneal transplantation is a very rare operation, as difficult to find donors and there are many complications after the procedure.
A team of researchers conducted an experiment on mice that have been clouding of the cornea. For the treatment of animals, scientists have used umbilical cord stem cells, from which grew the cells of the cornea (keratocytes). Three months after transplantation all mice were alive and they have observed the minimum number of signs of rejection with a significant improvement in the transparency of the cornea.
According to experts, this kind of treatment might suit, and people having problems with the transparency of the cornea. However, for the use of such therapy is necessary to conduct clinical research and ensure its safety for human health.
