Tested stem cells in Stroke Patients

A British stroke patients received injections of two million nerve stem cells to repair brain cells that die. The test was first in the world is expected to help patients recover from stroke by stimulating the brain using a mature nerve cells.The method is considered controversial because it uses stem cells (stem cells) that developed in the laboratory are taken from human fetal brain candidates aged 12 weeks.Stem cells are master cells in the human body that can transform itself into various mature cell types.Laruence Dunn, neurosurgeon, managed to inject stem cells in stroke patients first since the methods of embryonic stem cells is permitted."In this experiment we find out the security and the possibility of stem cell implantansi where required surely follow carefully the patient," said Professor Keith Muir, a neurologist from Glasgow University, UK.He added that some of the injected neural stem cells will automatically convert itself into a nerve. As is known, the brain cells of stroke patients die due to lack of oxygen. The development of this therapy will be monitored for two years.In trials on mice are known, stem cells also trigger the body's repair processes, such as helped the growth of blood vessels in the brain just as well as spur the brain to grow the stem cell population itself.Stem cell experiments in mice have been conducted since 10 years ago by scientists from the Albert Einstein College of Medicine, USA. In such research, experts managed to overcome the damage caused by stroke in rat brains injected stem cells.Within six weeks, the stem cells that grow into nerve cells that mature and prove the possibility of that method in mammals.Until in 2011, had 13 patients involved in this trial will receive injections of stem cells with an increased dose. "The dose will be increased to 20 million cells," said Muir.All patients enrolled with a median age above 60 years and male sex. They suffered an ischemic stroke, caused by blockage of blood vessels to the brain, and not successful in the treatment therapy.
