Scientists have discovered a new way to generate human motor nerve cells in a development that will help research into motor neurone disease.
A team from the Universities of Edinburgh, Cambridge and Cardiff has created a range of motor neurons – nerves cells that send messages from the brain and spine to other parts of the body – from human embryonic stem cells in the laboratory.
It is the first time that researchers have been able to generate a variety of human motor neurons, which differ in their make-up and display properties depending on where they are located
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.
Hebrew University of Jerusalem
Researchers at the Hebrew University of Jerusalem discovered a method to potentially eliminate the tumor-risk factor in utilizing human embryonic stem cells, said the university on Wednesday.
The researchers’ work paves the way for further progress in the promising field of stem cell therapy, said the press release of the university sent to Xinhua.
According to the release, human embryonic stem cells are theoretically capable of differentiation to all cells of the mature human body (and are hence defined as “pluripotent“).
This ability, along with the ability to remain undifferentiated indefinitely in culture, make regenerative medicine using human

Madison, Wisconsin – Soon, some treatments for blinding eye diseases might be developed and tested using retina-like tissues produced from the patient’s own skin, thanks to a series of discoveries reported by a team of University of Wisconsin-Madison stem cell researchers.
The team, led by stem cell scientist and ophthalmologist Dr. David Gamm of the UW School of Medicine and Public Health and former UW scientist Dr. Jason Meyer, used human embryonic stem (ES) cells and induced pluripotent stem (iPS) cells to generate three-dimensional structures that are similar to those present at the earliest stages of retinal
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
