A team of researchers led by University of Wisconsin-Madison professor David Gamm is developing a transplantable retinal patch intended to help restore vision to military personnel blinded in the line of duty and to treat individuals with degenerative eye diseases such as macular degeneration.
The technology, funded by a U.S. Department of Defense grant exceeding $5 million, will be based on a system in which human induced pluripotent cells are used to generate light-responsive eye cells called photoreceptors along with the cells that support them, called retinal pigment epithelium.
