      University of Toronto researchers were able to encase stem cells in a gel-like biomaterial that enhanced their ability to survive injection into a transplant site.

      Using a blind mouse model, they were able to restore some visual function when photoreceptor progenitor cells were injected into the retina. They also used this technique to restore some function in a mouse model of stroke, using neuronal stem cell injections into the brain. The hydrogels not only keep stem cells viable, but also encourage their integration into the target tissues.
