A new technique has shown that allowing embryonic stem cell research and having laws that regulate and monitor this type of research does not prevent the development of less ethically controversial techniques, rather, it creates incentives for them. In Valencia, at the same clinic where the first Spanish embryonic stem cell lines were obtained, the same researcher who developed the lines has obtained embryonic stem cells without destroying the embryo.
The announcement was made by Carlos Simòn, making the Centro de Investigaciòn Prìncipe Felipe (CSPF) the third laboratory in the world
U.S. researchers have found that a supplemental protein may help restore impaired mobility of people who suffer from a stroke.
Naturally occurring in humans, the protein has proved to work well in restoring motor function in rats after a stroke, according to two new studies by researchers at the University of California, Irvine (UCI).
The researchers hope that the protein will also help humans.
Administered directly to the brain, the protein restores 99 percent of lost movement; if it’s given through the nose, 70 percent of lost movement is regained. Untreated rats improve by only 30 percent.

Stem cells from the brain could be transplanted into the ear to cure hearing loss.
Often, age and overstimulation can damage ciliated cells that act like small microphones, allowing us to hear sounds, noise, and voices and are located in the deep ear (cochlea). About 10% of people experience damage to the cells in this area which leads to hearing loss. The loss of these cells is irreversible, but according to the Proceedings of the National Academy of Sciences (PNAS), a group of scientists from the University of California substituted them with stem cells taken from another area
Scientists at the University of California have found a potential new use for human embryonic stem cells: helping cancer patients recover the cognitive function lost when their brains are treated with radiation.
People with tumors in their head or neck often undergo radiation therapy after the cancer is surgically removed. Radiation helps kill malignant cells left behind. But it also can debilitate the hippocampus, the brain region responsible for learning, memory and processing of spatial information.
The researchers wondered whether embryonic stem cells could pick up the slack.
So they radiated the heads of 18 rats. Two days later, six of those

Promising results from a small study may offer hope for the treatment of multiple sclerosis (MS).
Researchers from the University of California – San Diego report dramatic improvement after treating MS patients with stromal vascular fraction (SVF) stem cells from a patient’s own body fat. They say the SVF therapy can limit the body’s immune system reaction and promote the growth of new myelin – the fatty “insulation” on axons in the brain, which breaks down in patients with MS.
“None of the presently available MS treatments selectively inhibit the immune attack against the nervous system, nor do they
