Retina Created from Human Embryonic Stem Cells

Wow!

UC Irvine scientists have created an eight-layer, early stage retina from human embryonic stem cells, the first three-dimensional tissue structure to be made from stem cells.

It also marks the first step toward the development of transplant-ready retinas to treat eye disorders such as retinitis pigmentosa and macular degeneration that affect millions. "We made a complex structure consisting of many cell types," said study leader Hans Keirstead of the Reeve-Irvine Research Center and the Sue and Bill Gross Stem Cell Research Center at UCI. "This is a major advance in our quest to treat retinal disease."

"Creating this complex tissue is a first for the stem cell field," Keirstead said. "Dr. Gabriel Nistor in our group addressed a really interesting scientific problem with an engineering solution, showing that gradients of solutions can create complex stem cell-based tissues."

The retina is the inside back layer of the eye that records the images a person sees and sends them via the optic nerve from the eye to the brain. Retinal diseases are particularly damaging to sight. More than 10 million Americans suffer from macular degeneration, the leading cause of blindness in people over 55. About 100,000 have retinitis pigmentosa, a progressive, genetic disorder that usually manifests in childhood.

"What's so exciting with our discovery," Keirstead said, "is that creating transplantable retinas from stem cells could help millions of people, and we are well on the way."

Nice so this means "The Kidz" will be able to do shots of vodka through there eyes and get them fixed at the expense of everyone else
