A first-of-its-kind stem cell transplant has changed the life of a man who was left blind in one eye following a firework accident. He remembers the moment when he walked into his Airbnb in Massachusetts and could see the bright blue color of his comforter. At that time, he was about eight months out from his firework injury. "I'll never forget [that moment]," Nick Kharufeh said. "And it sounds so little. It's just like, 'Okay, a little blue comforter.' But in that moment that was everything to me, and I literally cried for so long." Read more about the surgery and Kharufeh’s recovery @LiveScience:

Type 1 diabetes develops when the body destroys its own insulin-producing cells.

Using stem cells to replace them could be a way to get around donor shortages and transplant complications. Here’s how:

Emergence of Sox & POU transcript. factors predates origins of animal stem cells

ScienceDailyScientists recreate mouse from gene older than animal lifeAn international team of researchers has achieved an unprecedented milestone: the creation of mouse stem cells capable of generating a fully developed mouse using genetic tools from a unicellular organism, with which we share a common ancestor that predates animals. This breakthrough reshapes our understanding of the genetic origins of stem cells, offering a new perspective on the evolutionary ties between animals and their ancient single-celled relatives.

Researchers challenge longstanding theories in cellular reprogramming
sciencedaily.com/releases/2024

* claim: neural crest stem cells = source of reprogrammed neurons found by other researchers
* refutes: any developed cell can be induced to switch identity to completely unrelated cell type thru infusion of transcription factors

Neural crest precursors f. skin are primary source of directly reprogrammed neurons

ScienceDailyResearchers challenge longstanding theories in cellular reprogrammingA team led by researchers has discovered that a group of cells located in the skin and other areas of the body, called neural crest stem cells, are the source of reprogrammed neurons found by other researchers. Their findings refute the popular theory in cellular reprogramming that any developed cell can be induced to switch its identity to a completely unrelated cell type through the infusion of transcription factors.

Good article, but it might be helpful to use the term "blood stem cell" intead of just "stem cell".

Just this week my daughter was taught at school that "stem cells can make every cell type". My daughter volunteered that adult stem cells only make cells within their own tissue (*proud mum* 😊 ). Teacher told her that she was getting confused 😖 🙄

This matters. There are still many exploitative disproved rogue therapies that feed on this misconception.
