“Researchers have grown part of an eye in a lab dish, using a type of stem cell made from a piece of skin.
They said the little retina started growing and developing on its own — an important step towards creating custom-tailored organs in the lab.”
Earlier this month scientists successfully created a functioning human retina using iPSCs (induced pluripotent stem cells). But that’s not the cool part. What’s actually amazing is that they did very little to make this happen.
Wait what?! Ok let me explain. These researchers took some of these cells from a tiny little piece of human skin, basically rewound time as far as these cells are concerned and pushed them back to a more-or-less embryonic state, sent signals to some genes manipulating them to form a retina, and then let it do it’s thing. And it was a success! This little retina is living in a dish just sensing light and being a badass little organ. Even the scientists didn’t realize this would happen so naturally
