USC researchers begin early trial of dopamine-producing stem cell implants for Parkinson’s

6. februar 2026 Rapporteret af AI Billede genereret af AI Faktatjekket

Keck Medicine of USC researchers are testing an experimental approach to Parkinson’s disease that implants lab-grown, dopamine-producing cells into a movement-control region of the brain. The early-stage Phase 1 REPLACE trial involves up to 12 people with moderate to moderate-severe Parkinson’s disease, and the U.S. Food and Drug Administration has granted the study fast-track designation.

Cambridge study reveals potential to reverse nerve damage

Researchers at the University of Cambridge have developed miniature lab-grown models of the human brain and spinal cord that show damaged nerve fibers can regain the ability to regrow under certain conditions.

Swedish team restores blood sugar control in diabetic mice

7. maj 2026 Rapporteret af AI

Researchers in Sweden have created insulin-producing cells from human stem cells that reversed diabetes symptoms when transplanted into mice. The cells matured after placement in the eye and maintained glucose regulation for months. The work was published in Stem Cell Reports.

Stem cell therapy restores vision in AMD patients

A pioneering clinical trial at the University of Michigan has demonstrated that adult stem cell transplants can safely improve vision in patients with advanced dry age-related macular degeneration. Early results from six participants show significant sight gains without serious side effects. Researchers are now evaluating higher doses in additional patients.

Fat-derived stem cells repair osteoporotic-type spine fractures in rats

11. november 2025 Rapporteret af AI Faktatjekket

Researchers at Osaka Metropolitan University report that stem cells taken from body fat, formed into bone-leaning spheroids and paired with a common bone-reconstruction material, improved healing and strength in rat models of osteoporotic vertebral fractures. The preclinical findings, published in Bone & Joint Research, point to a potential future therapy if validated in humans.

Study links graying hair and melanoma to stress responses in pigment stem cells

Japanese researchers report that hair graying and melanoma can arise from the same melanocyte stem cells, which take different paths depending on DNA damage and local signals. Published online October 6, 2025 in Nature Cell Biology, the University of Tokyo-led study outlines a protective differentiation program that promotes graying and how carcinogens can subvert it to favor melanoma.

Scientists reverse brain aging in mice using stem cells

23. oktober 2025 Rapporteret af AI

Researchers at Cedars-Sinai have developed young immune cells from human stem cells that reversed signs of aging and Alzheimer's disease in mice. The treatment improved memory and brain structure in the animals. The findings, published in Advanced Science, suggest potential for personalized therapies against cognitive decline.
