Lab-Grown Retina from Stem Cells Responds to Light | Teacher Tools and Tips |

Researchers at Johns Hopkins pulled it off, they reported in a paper published recently in Nature Communications. They cultivated a three-dimensional complement of retinal tissue, including functioning photoreceptor cells that responded to light, from induced pluripotent stem cells.

“We have basically created a miniature human retina in a dish that not only has the architectural organization of the retina but also has the ability to sense light,” said Valeria Canto-Soler, the senior author and an assistant professor of ophthalmology at Johns Hopkins medical school.
