Cultured stem cells from eyes helped improve the sight of eight patients with Limbal Stem Cell Deficiency, a painful, blinding disease, British doctors said.
The patients’ own corneal cells were cultured and used to reduce corneal cloudiness from the disease, The North East England Stem Cell Institute, Newcastle, England, reported in a release Thursday.
Limbus stem cell transplants (a layer of adult stem cells surrounding the cornea responsible for restoring corneal epithelium naturally during life) rebuild the ocular surface when damaged due to chemical and physical agents (like lime). They also repair “injuries” due to improper use of contact lenses. Vincenzo Sarnicola, a cornea and stem cell transplant expert, leading ocular surface specialist in Grosseto, Professor of Ocular Surface Surgery at the University of Siena, and President of the Italian Stem Cell and Ocular Surface Society (SICSSO) explained, “When the ocular surface loses its stem cells it is unable to defend
In a major achievement, the scientists have managed to get a patent for growing stem cells of the cornea. The cells will be grown on a synthetic material, called Mebiol Gel, which will be used in the process of transplant.
For a long time scientists across the world have been trying to get the patent. The declaration was made by the researchers at Sankara Nethralaya and Nichi-In Biosciences Sankara Nethralaya and Nichi-In Biosciences on Friday.
The new procedures have been devised and patented by these two institutes. A synthetic substance was used by the researchers for growing the corneal limbal stem
As Pratik Patil babbles into the pay phone, there is little to indicate that the 27-month-old has been living out of hospitals for over a year. His opaque left eye tells a different story though – his impaired vision is obvious.
On Wednesday, doctors at Bombay Hospital in New Marine Lines announced that they were trying out a new stem cell therapy to restore vision to his affected eye. “In six months, we will know whether he can see or needs a corneal transplant,” said Dr Sonia Nankani of the hospital’s Taparia Opthalmology Centre.
Son of a farmer, Pratik’s saga began
Breakthrough in Stem Cell Research for the Cornea
Stem Cell Research using the patient’s own Adult Stem Cells has brought us another great discovery- Stem Cell Contact Lens. In Australia, a group of doctors in a research study treated 3 patients who had some form of cornea problems and they all were able […]
