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
Researchers in Japan said on Wednesday they have succeeded in growing human kidney tissue from stem cells for the first time in a potential breakthrough for millions with damaged organs who are dependent on dialysis.
Kidneys have a complex structure that is not easily repaired once damaged, but the latest findings put scientists on the road to helping a diseased or distressed organ fix itself.
Kenji Osafune of Kyoto University said his team had managed to take stem cells — the “blank slates” capable of being programmed to become any kind of cell in the body — and nudge them specifically
Scientists, including an Indian researcher, have found a previously unknown stem cell which is the real culprit behind heart attacks, a landmark finding which, they say, could revolutionize treatments for the cardiac disease.
Until now, it has been thought that vascular health problems were triggered by smooth muscle cells, but a team at the University of California in Berkeley identified a previously unknown stem cell, which causes the arteries to harden when it multiplies.
The groundbreaking work is set to completely change how heart attacks and strokes are treated, dramatically cutting the number of deaths, the researchers said.
“For the first time,
Japanese researchers have successfully grown hair on hairless mice by implanting follicles created from adult stem cells, they announced Wednesday, sparking new hopes of a cure for baldness.
Led by professor Takashi Tsuji from Tokyo University of Science, the team bioengineered hair follicles and transplanted them into the skin of hairless mice.
The creatures eventually grew hair, which continued regenerating in normal growth cycles after old hairs fell out.
When stem cells are grown into tissues or organs, they usually need to be extracted from embryos, but Tsuji and his researchers found hair follicles can be grown with adult stem cells, the
Some stem cells can lay dormant for more than two weeks in a dead person and then be revived to divide into new, functioning cells, scientists in France said.
The research, published in the journal Nature Communications, unlocks further knowledge about the versatility of these cells, touted as a future source to replenish damaged tissue.
“Remarkably, skeletal muscle stem cells can survive for 17 days in humans and 16 days in mice, post mortem well beyond the 1-2 days currently thought,” they said in a statement.
The stem cells retained their ability to differentiate into perfectly functioning muscle cells, they found.
