USA – Science Awards Reprogrammed Adult Stem Cells

According to Science magazine, reprogrammed adult stem cells that regress to an embryonic state and have the same ability to transform into all the different tissues in the human body just like embryonic stem cells are the most important discovery of 2008. The prestigious magazine awarded the so-called ethical stem cells for their possible efficiency in curing degenerative diseases like Alzheimer’s, Parkinson’s, and muscular dystrophy without the ethical implications associated with embryonic stem cell use. The direct observation of extrasolar planets and the development of new superconductors were also in the ranking.

Grant money could speed stem cell cures

Dr. Karen Aboody estimates that she has cured several hundred mice of a cancer of the central nervous system called neuroblastoma.
First she injected them with specialized neural stem cells that naturally zero in on the tumors and surround them. Then she administered an anti-cancer agent that the cells converted into a highly toxic drug (…)

For 3 1/2 years, the agency focused on the basic groundwork needed to someday use human embryonic stem cells to replace body parts damaged by injury or disease. Such cures are still far in the future.
Now the institute has a more immediate goal: boosting therapies

Europe’s first embryonic stem cell trial at Moorfields

British regulators have given Moorfields approval to begin trials using retinal cells derived from human embryonic stem cells (hESCs).

Twelve patients with Stargardt’s disease will have the cells injected into the eye. You can read more about the trial here.
Although there is great excitement about the trial, Julia knows that the initial phase will simply check safety (…)

“It would be marvellous if I could get some of my sight-loss reversed”, said Julia. “Even if it simply halts the deterioration, that would be great. And the real benefit would be for children. It could mean they don’t need to lose any

Researchers Hail Stem Cells Safe for Human Use

Stem-cell science is a fast-moving field. Just three years since a Japanese researcher first reprogrammed ordinary skin cells into stem cells without the use of embryos, scientists at a Massachusetts biotech company have repeated the feat, only this time with a new method that creates the first stem cells safe enough for human use. The achievement brings the potentially lifesaving technology one step closer to real treatments for disease.

Dr. Robert Lanza, chief scientific officer at Advanced Cell Technology (ACT), reported today in the journal Cell that his team has created stem cells using human skin cells and four proteins.

USA – Blind Mice Sense Light Thanks to Stem Cells

Human embryonic stem cells implanted into mice specifically engineered to have a serious retinal dysfunction resulting in blindness have restored the animal’s capacity to sense light during tests.
The results, published in international magazine, Cell Stem Cell, were obtained in the United States by a research group in the Department of Biological Structure at the University of Washington in Seattle. The study, performed by Deepak Lamba, Juliane Gust, and Thomas Reh, demonstrated that it is possible to obtain retina progenitor cells from stem cells derived from the embryo. The researchers observed, “In principle, embryonic stem
