Scientists seeking new ways to fight maladies ranging from arthritis and osteoporosis to broken bones that won’t heal have cleared a formidable hurdle, pinpointing and controlling a key molecular player to keep stem cells in a sort of extended infancy. It’s a step that makes treatment with the cells in the future more likely for patients.
Controlling and delaying development of the cells, known as mesenchymal (pronounced meh-ZINK-a-mill) stem cells, is a long-sought goal for researchers. It’s a necessary step for doctors who would like to expand the number of true
Japanese researchers have been able to improve the symptoms of Parkinson’s disease in monkeys by transplanting nerve cells derived from embryonic stem cells into their brains, the team has announced.
The finding is the world’s first reported success of its kind with a primate, according to the research team led by Associate Prof. Jun Takahashi of Kyoto University‘s Institute for Frontier Medical Sciences. It has been released in the online edition of U.S. journal Stem Cells.
After the transplant, the monkeys, which had been almost unable to move, showed improvements in their symptoms to the point where they became able to

Patients suffering from blindness now need not wait for donors as doctors have found a way to treat many with the stem cells derived from the cornea of a dead body.
Doctors at the AIIMS and a private clinic in the national capital are using corneal surface stem cells from a cadaver’s (dead person) eye for curing corneal injuries in many.
“We have used the corneal surface stem cells of cadaver’s eye for patients with corneal injury and have been able to correct many vision,” Dr Radhika Tandon, Associate Professor, Department of Opthalmology, AIIMS said, adding “this has been
University of Queensland scientists have developed a world-first method for producing adult stem cells that will substantially impact patients who have a range of serious diseases.
The research is a collaborative effort involving UQ’s Australian Institute for Bioengineering and Nanotechnology (AIBN) and is led by UQ Clinical Research Centre’s (UQCCR) Professor Nicholas Fisk.
It revealed a new method to create mesenchymal stem cells (MSCs), which can be used to repair bone and potentially other organs.
“We used a small molecule to induce embryonic stem cells over a 10 day period, which is much faster than other studies reported in the literature,” Professor
A new biomaterial that enhances the ability of stem cells to regenerate into nerves and body parts has been developed by Australian and British scientists.
The work was a result of a joint study undertaken by the researchers at the Melbourne-based Monash University and UK-based University of Warwick.
Other biomedical “scaffold” materials, which act as templates for tissue regeneration, already exist but they cannot communicate effectively with the cells they are trying to influence.
The researchers have created a more advanced material that targets specific cells and provides clear signals to these cells to enhance regeneration.
