Johns Hopkins researchers create ‘mini-retina’ out of stem cells

Scientists create ‘mini-retina’ in lab dish (via AFP) In another step towards reversing degenerative vision loss, scientists said Tuesday they had coaxed stem cells into growing into a tiny, light-sensing retina in a lab dish. The study is an important technical feat in using reprogrammed cells, whose…   [Image via…

Researchers turn infertile men’s skin tissue into sperm cells

Researchers at Stanford convert skin cells into stem cells, which became human sperm cells when transplanted into mice’s testes Scientists have turned skin tissue from infertile men into early-stage sperm cells in a groundbreaking study that raises hopes for new therapies for the condition. The unexpected success of the procedure…

‘Game changing’ low-tech stem-cell breakthrough questioned by researchers

A Japanese research institute Tuesday said it was probing its own study that promised a 'game changer' way to create stem cells, a feat hailed as revolutionary for the fast-developing field. The findings, published by Japanese researcher Haruko Obokata……

Stem cell discovery could eliminate need for embryo research and usher in human cloning

Any cell can be rewound to a pre-embryonic state, according to stem cell researchers. Scientists in Japan and at Harvard said they found that stem cells, which can transform into any tissue and potentially regenerate the body, could be quickly made by dipping blood cells into an acid bath or…

Scientists grow human brain tissue from stem cells

cientists said Wednesday they had used stem cells to grow primitive human brain tissue for use in studying disorders and early development of this most complex of organs. They used the cells to grow what they dubbed “cerebral organoids” — pea-sized blobs of 3D brain tissue in a Petri dish,…

Breakthrough: Scientists use caffeine to clone stem cells from human skin

Human stem cells have for the first time been cloned from adult skin cells through the use of hollowed-out embryos as a type of organic petri dish, scientists at Oregon Health & Science University (OHSU) announced Wednesday in a study published by the scientific journal Cell. And in a surprising…

South Korean toddler gets first ever windpipe transplant

An international team of surgeons has successfully given a South Korean-Canadian toddler a life-saving windpipe transplant made from plastic fibers and some of her own stem cells. Hannah Warren, 2, was born without a trachea and is now the youngest person to ever receive a bio-engineered organ, after an operation…

Scientists ‘print’ 3D object with stem cells

Scientists on Monday said that for the first time they had printed 3D objects using human embryonic stem cells, furthering the quest to fabricate transplantable organs. Once fine-tuned, the technology should allow scientists to make three-dimensional human tissue in the lab, eliminating the need for organ donation or testing on…

Study raises hopes of cure for baldness

Japanese researchers have successfully grown hair on hairless miceby implanting follicles created from stem cells, they announced Wednesday, sparking new hopes of a cure for baldness. Led by professor Takashi Tsuji from Tokyo University of Science, the team bioengineered hair follicles and transplanted them into the skin of hairless mice. The creatures eventually grew hair, which continued regenerating…

Researchers develop stem cells that attack and destroy HIV

Scientists from the University of California Los Angeles have found that genetically engineered human stem cells can suppress HIV in living mice, raising the hope for a breakthrough cure for HIV patients. In a recent study from the journal PLoS Pathogens, researchers wanted to go further than previous studies that…
