German scientist found a kind to turn a few days ago gene operates new method, use high frequency laser to wear an alveolus in cellular film surface, can achieve be opposite the cell transplants below the state of affairs with structural very little damage originally the purpose of gene material. According to xinhua net report, in current gene research, through turning the method of gene with period achieve change life style the purpose such as shape of certain primary inherent quality and remedial disease, already became one of methods that use oftener and oftener. Existing transplanting technology connects regular meeting to be destroyed to cellular structure very big and cause transplanting efficiency low, and the gene material that is transplanted often also cannot well with original material is united in wedlock inside the cell, function amounts to the effect not beautiful. It is reported, in the experiment, the scientist is used high frequency (pulse interval is ten million 1/100000000 second) , nearly high strenth, infra-red laser pulse, mix to the ovarian cell of animal of two kinds of experiments respectively nephritic cell undertakes " continuous firing " of type " bombard " , cause the aperture that an aperture minimum appeared on cellular film, smoothly transplanting entered target material. After this, this alveolus that the growth of cellular oneself helps cellular film go up once more " shut " , make cellular structure returns to normal. This kind of new method not only reliable and transplanting effect is good, improved transplanting efficiency greatly. It enters those who include to do a cell inside to material of heredity of the source outside successful transplanting all sorts of cells have important sense, will conduce to development giving new gene treatment and DNA vaccine have an inoculation to wait.
