LONDON: Scientists have for the first time turned adult human skin cells into stem cells, which can grow into any type of tissue in the body, using cloning techniques.
Using the cloning technique which produced Dolly the sheep in 1996, researchers were able to turn skin cells from a 35-year-old man and a 75-year-old man into stem cells, raising the prospect that body parts could be regenerated in old age.
Last year, a team of researchers had created stem cells from the skin cells of babies but it was unclear whether it would work in adults because cells mutate with age.
OHSU research demonstrates not all embryonic stem cells are equal; produces the world’s first primate chimeric offspring
Newly published research by scientists at Oregon Health & Science University provides significant new information about how early embryonic stem cells develop and take part in formation of the primate species. The research, which took place at OHSU’s Oregon National Primate Research Center, has also resulted in the first successful birth of chimeric monkeys — monkeys developed from stem cells taken from two separate embryos. The research will be published this week in the online edition of the journal Cell and will be
Medical researchers are trying a new treatment for low back pain. Their hope is that harvesting and then re-injecting the body’s own bone marrow — which is rich in stem cells — may repair worn-out discs in the spine.
In a small new study, the approach appeared to be safe — and none of the patients reported that their pain got worse after the procedure.
But both the doctors who are testing the technique and outside experts say much more research is needed before they can say whether the treatment offers real relief.
“I tell everybody that this is experimental, with a
