Retinal cells grown from stem cells can reach out and connect with neighbors, according to a new study, completing a “handshake” that may show the cells are ready for trials in humans with degenerative eye disorders.
Interphotoreceptor matrix proteoglycan 2 (IMPG2) mutations cause a severe form of early-onset retinitis pigmentosa (RP) with macular involvement.
A grant from Fighting Blindness Canada will allow Dave Gamm to further test the efficacy of an induced pluripotent stem cell (iPSC) derived treatment that aims to replace damaged photoreceptor cells and restore some measure of vision.
Polymeric scaffolds are revolutionizing therapeutics for blinding disorders affecting the outer retina, a region anatomically and functionally defined by light-sensitive photoreceptors. Recent engineering advances have produced planar scaffolds optimized for retinal pigment epithelium monolayer delivery, which are being tested in early stage clinical trials.
The new project, titled Outer Retina Reconstruction for Combat Afflictions or ORRCA, is a collaboration between the McPherson Eye Research Insitute at UW‒Madison, the UW School of Medicine and Public Health, the UW College of Engineering, the University of Birmingham (UK) and British Ministry of Defence and the National Eye Institute. It is funded by a grant for more than $5 million from the U.S. Department of Defense (DOD).
Waisman Center investigator David Gamm, MD, PhD, and Waisman affiliate Kris Saha, PhD, have published a proof-of-concept method to correct Best disease – an inherited form of macular degeneration that causes blindness, and that is …
A big congratulations to researcher Kim Edwards and Waisman investigator David Gamm, MD, PhD, on winning the inaugural Randy Wheelock Research Award. Gamm is also an associate professor of ophthalmology and visual science as well as the director of the McPherson Eye Research Institute.
A recent story on Channel 3000 highlights the efforts by the family of Kenzi Valentyn to raise money for vision research in their daughter’s name. Waisman investigator David Gamm focuses on using stem cells to …
Numerous protocols have been described that produce neural retina from human pluripotent stem cells (hPSCs), many of which are based on the culture of 3D organoids. While nearly all such methods yield at least partial segments of highly mature-appearing retinal structure, variabilities exist within and between organoids that can change over a protracted time course of differentiation.
To mark the 20th anniversary of the stem cell discovery at UW-Madison, the Wisconsin State Journal featured a series of stories on stem cell research, highlighting the work of Waisman Center investigators David Gamm, Anita …
