Investigator people point out, they had proved in the experiment, the oxygen of the red blood cell that with human embryo dry cell education goes leaves a curve, leaving a curve with the oxygen of normal red blood cell is similar, and also be worth as PH, 2, glycerine of 2 phosphoric acid changes 3- acerbitily and change, carry what also passed decisive test with the ability that releases oxygen to detect. "Important the first step " Although be compared with the photograph of red blood cell of adult, the red blood cell of sex of dry cell source more resemble fetal the red blood cell with embryo, but education hind is passed outside body, still showed the trait of grown red blood cell. In developing a process, β - globulin (β - globulin is the commonnest haemal protein hematin in adult blood) amount from 0% increased 16% above. The scientist points out, most important is, the cell can experience a few level in mature process, include the smaller and smaller, feature that shows more and grown cell gradually, the protein with expressive for instance important other and nucleolus condense. Person embryo does red blood cell of cellular source sex whether a when enter clinical applying crucial question is, these cells whether finish when be fostered outside body go nuclear process, become mature red blood cell thereby. Result, the result of this research makes clear, the red blood cell that has 60% above was finished go nuclear process, become grown red blood cell thereby. Investigator people in the article summary points out: The result of this research makes clear, person embryo the become divided with dry many cell fosters a success can the red blood cell of the gender that carry oxygen is feasible. Investigator people the hope will come one day, the person that this one technology can be blood transfusion of O electronegative red blood cell is offerred " all-purpose the person that offer blood " . Of institute of blood of lungs of American country heartAct as agentDirector Susan Shurin calls this one research as a result " important the first step " , she points out, investigator people these cells are bred in test tube, foster its maturity, the red blood cell that makes its arise in a lot of respects and normal person is similar, but these cells are denied in human body internal energy survive still need further research to prove. Still have a very serious problem, it is immune system. The immune system of human body will identify the antigen of saccharide of surface of red blood cell, if these antigen and sign of immune system place are other not conform to, can be regarded as an alien, suffer the attack of immune system thereby. Although still much work wants to do, but at least scientists forward right way strode very important one step. [of on one page1] [2] issues one page
