Lab-grown retinas explain why people see colors dogs can’t
From Johns Hopkins University 12/01/24 With human retinas grown in a petri dish, researchers discovered how an offshoot of vitamin A generates the specialized cells that enable people to see millions of colors, an ability that dogs, cats, and other mammals do not possess. “These retinal organoids allowed us for the first time to study […]
Fish-like genetic program used to turn human retinal cells into neurons
From International Society for Stem Cell Research 10/12/23 Loss of neurons in in the retina due to trauma or disease leads to vision impairment or blindness, a process which is irreversible in humans. Interestingly, some animals like fish have the built-in ability to regenerate retinal neurons by turning another retinal cell type called “Muller glia” […]
