Chinese scientists have bred mice from cells that might offer an alternative to human embryonic stem cells, producing the most definitive evidence yet that the technique could help sidestep many of the explosive ethical issues engulfing the controversial field but raising alarm that the advance could lead to human cloning and designer babies.
In papers published online Thursday by two scientific journals, separate teams of researchers from Beijing and Shanghai reported that they had for the first time created virtual genetic duplicates of mice using skin cells from adult animals that had been coaxed into the equivalent of embryonic stem
There’s a medical breakthrough for the deaf.
Scientists at United Kingdom’s Sheffield University have created stem cells from embryos to replace damaged cells in the inner ear — reversing hearing loss.
The embryonic stem cells could be converted into workable hearing cells for people born with inherited hearing problems and who’ve suffered damage to their ear cells during their lifetime, according to the scientists.
The breakthrough stem-cell discovery is “incredibly promising” and “opens up exciting possibilities,” Dr. Ralph Holme, a biomedical researcher, told the British Broadcasting Corporation.
But the stem-cell research could be halted by critics who argue that the controversial
All over the world there are desperate patients looking for institutions that promise to heal them with stem cells. But the treatments that are promised must be controlled and regulated, said two scholars in Science magazine. Today, recognized treatments with stem cells involve blood diseases or immune system defects, wrote the Thai researcher Sorapop Kiatpongsan and his Japanese colleague Douglas Sipp. In reality, many other treatments have been offered without proof of their effectiveness.
For example, treatments are being offered to cure heart disease, autism, Down’s syndrome, and epilepsy. These treatments are ineffective and are mainly
Five years after the passage of Proposition 71, the California Institute of Regenerative Medicine is awarding grants for stem-cell research targeted at clinical applications. In what both the San Diego Union-Tribune and Knight Science Journalism Tracker are calling an “irony,” ten of the 14 grants are going to researchers working with adult stem-cells.
On Thursday, October 29, the New York Times reported: “In a tacit acknowledgment that the promise of human embryonic stem cells is still far in the future, California’s stem cell research program on Wednesday awarded grants intended to develop therapies using mainly other, less controversial cells.

The subject of producing artificial blood from stem cells has become a hot topic in Italy. “Italy is close to reaching the same objective announced by British researchers, on a similar timeframe,” therefore possibly in three years, “but using adult stem cells. Certainly, it is one thing to say that in three years we will begin the experimental phase, it’s another thing to speak about industrial production. It needs to be specified that the procedure to produce artificial blood is very expensive. Therefore this would be a complementary solution, which will not replace
