And now there are three: in the wake of announcements from laboratories in Oregon and California that they had created human embryos by cloning cells of living people, a lab in New York announced on Monday that it had done that and more.
In addition to cloning the cells of a woman with diabetes, producing embryos and stem cells that are her perfect genetic matches, scientists got the stem cells to differentiate into cells able to secrete insulin.
That raised hopes for realizing a long-held dream of stem cell research, namely, creating patient-specific replacement cells for people with diabetes, Parkinson’s disease,
For the first time, cloning technologies have been used to generate stem cells that are genetically matched to adult patients.
Fear not: No legitimate scientist is in the business of cloning humans. But cloned embryos can be used as a source for stem cells that match a patient and can produce any cell type in that person (…)
“This is a dream that we’ve had for 15 years or so in the stem cell field,” said John Gearhart, director of the Institute for Regenerative Medicine at the University of Pennsylvania. Gearhart first proposed this approach for patient-specific stem cell generation in
Regenerative medicine took a step forward on Monday with the announcement of the creation of the first disease-specific line of embryonic stem cells made with a patient’s own DNA (…)
“This is a really important step forward in our quest to develop healthy, patient-specific stem cells that can be used to replace cells that are diseased or dead,” said Susan Solomon, chief executive officer of NYSCF, which she co-founded in 2005 partly to search for a cure for her son’s diabetes.
Stem cells could one day be used to treat not only diabetes but also other diseases, such as Parkinson’s and
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
