"We're able to produce significant numbers of photoreceptor cells and other retinal cell types…which are lost in many disorders," Jason Meyer, a research scientist at the University of Wisconsin–Madison, said in a prepared statement. The findings "could serve as a foundation for unlocking the mechanisms that produce human retinal cells," he noted.
The team relied on both embryonic stem cells and induced pluripotent stem (iPS) cells—made from cultured adult skin cells—to create the retinal cells. The researchers hope that by using the parallel methods of both embryonic and iPS cells, they can also shed some light on the differences between the two.
It’s Time to Stand Up for Science
If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in that two-century history.
I’ve been a Scientific American subscriber since I was 12 years old, and it helped shape the way I look at the world. SciAm always educates and delights me, and inspires a sense of awe for our vast, beautiful universe. I hope it does that for you, too.
If you subscribe to Scientific American, you help ensure that our coverage is centered on meaningful research and discovery; that we have the resources to report on the decisions that threaten labs across the U.S.; and that we support both budding and working scientists at a time when the value of science itself too often goes unrecognized.
