The scientist will induce the multi-functional stem cell's conversion ratio to improve to make an appointment hundredfoldly

Turn ordinary skin cells into inducing the multi-functional stem cell (i P S cells) And then carry on research of cloning etc., it is a hot field of stem-cell research in recent years, but this field has been receiving the restriction of cells with too low conversion ratio all the time. Britain>Magazine website deliver latest scientific research, say scientist find, block, can improve, invite success rate of transformation this hundredfold through genetic route 9.
5 scientific research groups from different countries reported relevant progress at the same time, the Japanese scientist including cultivating i P S cells at first stretches the scientific research group filled in the mountain. The scientist finds, called through blocking one " 53 pence " Route at gene,can last i P S the success rates of the cells cell improve until about 10 skin, it is about hundred times of the original conversion ratio.
At present, it is to inject 4 genes into cells to turn ordinary cells into the commonsense method of i P S cells through virus carriers; Some other methods can only use 2 or 3 genes, or does not use virus carriers, i P S that get will safe in cell, appear bad and mutant perhaps less, but the conversion ratio is lower too. The new discovery can improve the success rate of all transformation methods, give consideration to the efficiency and security better.
But the scientist reminds and says, " 53 pence " Inhibit the cell canceration, function that prevents growth of tumour, so is passing and blocking " 53 pence " When the route raises i P S cell conversion ratio, should pay attention to the potential risk too.
