Somatic cells can be reprogrammed into induced pluripotent stem cells (iPSCs) by defined factors. However, the low efficiency and slow kinetics of the reprogramming process have hampered progress with this technology. Here we report that a natural compound, vitamin C (Vc), enhances iPSC generation from both mouse and human somatic cells. Vc acts at least in part by alleviating cell senescence, a recently identified roadblock for reprogramming.
In addition, Vc accelerates gene expression changes and promotes the transition of pre-iPSC colonies to a fully reprogrammed state. Our results therefore highlight a straightforward method for improving the speed and
Stem Cell Research Brings About Another Miracle
Korean doctors have apparently regrown a patient’s jawbone using the patient’s own Adult Stem Cells in yet another amazing miracle that Adult Stem Cell research has brought us.
An 18 year old Korean boy who had to have most of his jawbone and his teeth removed due to a tumor […]
The Jumonjd3 protein is a sort of nervous system regulator, allowing stem cells to become neural cells. Researchers from the IFOM-IEO Campus of the European Institute of Oncology (EIO) in Milan, whose studies were published in Plos One magazine discovered the regulator protein. The researchers explained that the protein is an enzyme capable of activating the stem cell genes necessary to differentiate a cell into a nervous system cell.
The result, underlined the scientists led by Giusepe Testa, “adds an important perspective to understanding the intricate mechanisms of stem cell function.” This protein could soon become “a target to improve
Parkinson’s Disease – Medical world has struggled in finding permanent cure for this condition that usually affects men over the age of 50 years, but now this maybe changing with the advent of stem cell based research in regenerative medicine. A significant clinical human trial using these technique now seems feasible in the near future.
Stem Cells and its Potential:
Stem cells have the remarkable potential to develop into many different cell types in the body during early life and growth. In addition, in many tissues they serve as a sort of internal repair system, dividing essentially without limit to replenish
Ashok Chakravarti remembers the moment he went blind.
It was on February 18, 2002. He was at work, at a chemical plant, when a pipe carrying sodium hydroxide (caustic soda) started to leak.
“I was fixing the leak when the chemical splashed into my eyes,” he says. The accident damaged the outermost layer of his eyes, the cornea.
Chakravarti is among thousands of Indians who lose their sight in chemical accidents each year.
Today, some of those people can see again, thanks to scientists at the L.V. Prasad Eye Institute, in Hyderabad.
The institute is treating patients with stem cells – not the controversial
