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…
Turning urine into brain cells could help fight Alzheimer’s, Parkinson’s
Chinese researchers have devised a new technique for reprogramming cells from human urine into immature brain cells that can form multiple types of functioning neurons and glial cells. The technique, published today in the journal Nature Methods, could prove useful for studying the cellular mechanisms of neurodegenerative conditions such as…
Study reveals children’s cells may benefit mother’s body long after birth
A new study has shown that the bond between mothers and their children may be even more elemental than common wisdom and centuries of art and literature would have us believe. According to Scientific American, new research by the National Institute of Health indicates that mothers’ and children’s cells may…
Japan stem cell Nobel laureate to get research boost
Japan’s Nobel prize-winning Shinya Yamanaka will likely get up to 30 billion yen ($383 million) for his stem cell research over the next decade, an official said Wednesday. The Japanese science and technology ministry is looking at giving at least 2.7 billion yen of extra money to support Yamanaka’s work…
Nobel Prize-winning stem cell research holds dramatic potential
Research in reprogrammed cells, which on Monday earned the 2012 Nobel Prize, has been hailed as a new dawn for regenerative medicine but remains troubled by several clouds. Britain’s John Gurdon and Japan’s Shinya Yamanaka were honoured with the world’s paramount award in medicine for induced pluripotent stem cells (iPSCs).…
Healthy baby mice created from stem cells
Scientists have created mouse eggs from stem cells and used them to make healthy baby mice. The technique will help them study how eggs develop and also offers the potential to create eggs for infertile women. Mitinori Saitou of Kyoto University led a team that took stem cells from mice…
Researchers find cancer stem cells that cause tumor regrowth
Researchers presented evidence Wednesday for the existence of cancer stem cells, with three different studies seeking to end a decades-old scientific dispute about how tumours grow. The discovery should lead to new drugs targeting stem cells that cause tumours to reappear after cancer therapy, the teams argued in three scientific…
Stem cells can be harvested long after death: study
PARIS — Some stem cells can lay dormant for more than two weeks in a dead person and then be revived to divide into new, functioning cells, scientists in France said Tuesday. The research, published in the journal Nature Communications, unlocks further knowledge about the versatility of these cells, touted…
Scientists: Anti-psychotic drug also kills cancer
A drug with a long list of heavy side effects, commonly used to treat sufferers of schizophrenia, also possesses some startlingly potent anti-cancer properties, according to research published Thursday in the medical journal Cell. The drug, thioridazine, is usually dispensed as a last resort for schizophrenics whose symptoms did not…
