Transplanted human retinal stem cells can successfully regenerate

"We transplanted the cells early in the animals' development when all the nutrients and signals they needed for differentiation were still there," says lead author Brenda Coles, a U of T laboratory technician working under the supervision of Professor Derek van der Kooy in the Department of Medical Genetics and Microbiology. "When their eyes fully developed, the human cells survived, migrated into the sensory part of the eye and formed the correct cells."
