[/]: According to the United Kingdom the journal nature network version 19 January reported that United Kingdom scientists were allowed to begin a clinical trial to test the use of stem cell transplantation in the treatment of stroke of security and feasibility, it is the first time in clinical experiments using stem cells for the treatment of stroke and 12 will take part in an initial period of 6 to 24 months of security testing.
Experiment on Monday received a United Kingdom drugs and health products, with the approval of the Board, will be this year's second quarter, different doses of human neural stem cells will be transplanted into the brains of patients with stroke, to monitor the treatment of security and flexibility of the brain.
Study of stem cells from human embryos, researchers have added on a cell's genes, then in the laboratory for tissue culture, make it grow into a large number of experiments using stem cells.
Tissue culture, the researchers by gene in Add or remove a chemical substance to turn on or turn off the gene activity, remove the chemicals, the cells stop dividing to transplantation will not form a tumor.
Prior to this, the researchers have completed stroke mouse stem cells test, the results show that transplantation of stem cells promotes new vascular and neuronal regeneration, the mouse can regain control activities.
Stroke is the leading cause of death, is the main culprit of adult disability in developed countries, half of all stroke survivors will leave a permanent disability, the stem cell transplantation therapy will bring hope for stroke patients.
