This week in stem cells:
○ Japan treated the first patient with its newly approved iPS cell therapy for Parkinson's. A woman in her 50s got lab grown brain cells and is back at work.
○ Vertex reported that 10 of 12 people with type 1 diabetes no longer needed insulin one year after getting lab made islet cells.
○ In mice, Rockefeller scientists found that immune cells in the skin work like a thermostat, setting how hard skin stem cells work.
A Parkinson's cell therapy looks safe at 4 years. In 12 patients, bemdaneprocel (dopamine cell precursors made from stem cells) caused no deaths or dropouts from side effects. High dose motor scores (off meds) fell from 49 to 33.4. Small study, no placebo.

Thinning corneas got about 120 microns thicker in one year. A thin donor sheet placed inside the eye also helped keratoconus patients see better.

Scientists turned a blood sample into tiny beating hearts. In one woman's cells, a hormone helped in a way nobody expected. Same disease, different hearts.

Japan did the world's second surgery with heart patches made from iPS stem cells. A man in his 50s with severe heart failure, barely able to walk, got 3 thin heart muscle sheets. He is stable.

This month in stem cells:
○ Japan gave its first approved iPS cell therapy for Parkinson's.
○ 10 of 12 people with type 1 diabetes were off insulin a year after one infusion.
○ One stem cell drip cut broken bones 94% in 10 women with osteoporosis.

A new mouse study found blood stem cells that stay in a "deep sleep" as a hidden reserve, like spare batteries in a drawer. The results are in mice only so far.

Stem cells are already curing some blood cancers, and in 2025 a trial got 10 of 12 people with type 1 diabetes off insulin. They're also the center of a lot of hype.
Here are 8 questions people ask most, answered 🧵
🤖 Made with AI
Red flags:
🚩 One treatment that claims to fix many unrelated diseases
🚩 Testimonials instead of published data
🚩 Paying to join a "study"
Ask for an FDA approval or a ClinicalTrials.gov number. Real trials are public.
