New epiblast stem cells could aid research into new therapies

Stem cells, for the last few years, have been creating waves in the field of research and treatment. After cardiologists and vascular surgeons resorting to ‘adult stem cell therapy’ for treating heart disease, bringing promises for ‘no-option patients’ suffering from Coronary Artery Disease (Coronary Heart Disease), Cardiomyopathy, and Congestive Heart Failure, it is now, perhaps, the turn for the Parkinson’s patients to take its help. The discovery of yet another ‘new stem cell-type’ assures the optimistic and impertinent UK scientists with more research into curing several diseases using it. Perhaps, it can be a hope for Parkinson’s patients, with the disease responding to ‘stem cell therapy.’ Unlike the previously extracted animal stem cells that behaved very differently from human counterparts, the two new researches extracted rodent embryonic stem cells, which closely resemble that of humans. This eventually is building hopes in bringing in stem cell therapy into newer arenas. The new type of stem cells is named ‘epiblast stem cells,’ which Professor Roger Pederson claims to constitute “the missing link’ between mouse and human embryonic stem cells. Bolstering this research, another team of scientists at Oxford University, independently has come up with the same findings. Cuing with these new epiblast stem cell-lines, the future is sure to see potential stem cell therapies for painful and killer disease using human embryonic stem cells. Image

Embryonic stem cells can repair eyes

A company have claimed that — they have been able to repair the eye site in genetically altered mice using embryonic stem cells to repair damage. Massachusetts based Advanced Cell Technology have stated that they have been able to create blood vessel precursor cells out of stem cells, and are plans to test them in humans. Dr. Robert Lanza, vice president of research and scientific development at ACT, stated we figured out how to produce literally billions of so-called ‘hemangioblasts’ — the mythical cell in the embryo that gives rise to our entire blood and immune system as well as to the blood vessels in our body. We’ve also tested these cells in animals for the first time, and it turns out that they have incredible reparative potential. Their research may lead to the creation of treatments aimed at repairing the eyes of people with certain eye conditions that limit their site. The researchers said they injected hemangioblasts into animals with damaged blood vessels in retinas caused by diabetes or injuries. The cells appeared to have begun repairing the vessels within two days, the study said. The cells demonstrated a similar ability to regenerate blood vessels in rodents with injured hind legs, but seemed to have no effect on healthy vessels. The study is published online on Monday in Nature Methods, a journal of the London-based Nature group. Image Source
