Gene-edited stem cells treat HIV with mixed success, researchers find
For the first time, researchers have used CRISPR gene-editing technology to try to treat a person infected with Human Immuno-deficiency Virus (HIV). Scientists in China engineered human stem cells to mimic a rare form of natural immunity to the virus and transplanted them into a man with HIV and blood cancer.
‘Stem cells’ approved to mend human hearts for first time
Scientists in Japan now have permission to treat people who have heart disease with cells produced by a revolutionary reprogramming technique. The study published in the journal Nature is only the second clinical application of induced pluripotent stem (iPS) cells.
First mature human heart muscle grown from patient-specific stem cells
Scientists have grown the first human heart muscle that functions just like an adult's would. Instead of the nine months it takes for a baby's heart to develop in the womb, they grew a functioning heart from stem cells in just four weeks. Although researchers can grow many tissues, including the heart muscle, from stem…
Reprogrammed stem cells relieve Parkinson's symptoms in trials
Japanese researchers report promising results from an experimental therapy for Parkinson’s disease that involves implanting neurons made from ‘reprogrammed’ stem cells into the brain.
Transplanted stem cells become eggs in sterile mice
With an assist, an old mouse might be able to make new eggs.
