“Boston researchers have successfully regrown human corneal tissue – a feat that could potentially restore vision in the blind.

The achievement also marks one of the first times that scientists have constructed tissue using adult-derived human stem cells.-Researchers Regrow Corneas Using Adult Human Stem Cells’. FoxNews.com

Researchers recently made great strides in the field of regrowing human tissue– this time regrowing a human cornea using adult stem cells. This is an amazing feat. They discovered that not only is it possible to regrow a cornea using cells from the functioning eye of someone who is blind in only one eye, but they can also transplant cells from a donor and regrow that way. They tested all this on mice, but used human adult stem cells. This is pretty darn cool.

And why is this possible now? Well the original hold up was their inability to harvest a specific molecule called ABCB5, which is necessary when growing corneal tissue. These researchers discovered that a high concentration of these molecules can be found in the eyes limbus (basically the white part of your eye), which in hindsight makes perfect sense. Unfortunately these cells die when the eye goes blind, but people suffering from blindness have one good eye full of these little miracle-workers. And those with blindness in both eyes can receive a transplant, though they may need immune-suppression.

These leaves only one obvious question to be answered– do these mice see as mice see? Or do they now see as us humans do? Philosophical input is welcome…

The Ray Romano and Kevin James Celebrity Golf Classic to Benefit Advancement in Vision Research

https://i2.wp.com/blogs.ajc.com/radio-tv-talk/files/2009/04/aug2006-ray_romano.jpgLA JOLLA, Calif.–(BUSINESS WIRE)–The Ray Romano and Kevin James Celebrity Golf Classic will be held on Monday, November 16, 2009 at the El Caballero Country Club in Tarzana, California. This year’s golf classic will benefit the advancement in vision science at The Scripps Research Institute in La Jolla, California.

The celebrity tournament is an annual event hosted by television and film stars Ray Romano (Everybody Loves Raymond, Ice Age) and Kevin James (The King of Queens, Paul Blart: Mall Cop). Each year, Romano and James choose a cause to support that is close to their hearts. Funds raised by this year’s golf tournament will support the research and treating of such debilitating vision diseases as retinitis pigmentosa and macular degeneration.

“My scientific team and I greatly appreciate Ray and Kevin for choosing The Scripps Research Institute as the beneficiary of this year’s golf tournament. The Ray Romano & Kevin James Celebrity Golf Classic’s contribution will be dedicated to research on stem cells for RP and MD patients,” said Scripps Research Professor Martin Friedlander, M.D./Ph.D., who is also a practicing ophthalmologist at the Scripps Clinic.
