Report American scientist's first success " Plant " The human liver appears
On October 31, on the annual public discussion of research association of of American liver held in Boston, American scientist has shown the English walnut - sized human liver that they cultivated. According to November 1 report of information website of U.S.A.'s daily health, the person in charge of this project, majestic gram in N.C. State, U.S.A.? Regenerated associate professor of medical college Sha Yi of Rest of the good fortune? Ask for gram and say: "Perhaps the ones that appear to this research prospect, we feel very excited. This research is still in the elementary steps satin, a lot of technological difficult points still need to overcome. Not only how many a hundred million hepatocytes we not merely it takes to understand, but also could form the liver big enough, must judge it is safe that these organs are applied to the patient. " The participant of this research Petty Luo? Betty tower of Sri Lankan of Palestine says, this utilizes the human hepatocyte to cultivate in the laboratory out the liver for the first time. He says: "After we hope to be transplanted into patient's body, they can continue the normal work as in the laboratory. " In order to make this kind of organ, the scientist utilizes a kind of cleaner to remove all cells on animal's liver, only have a collagenic quality left " The support " ,Or support the structure. Then use two kinds of human hepatocytes (development incomplete hepatocyte and endothelial cell, a lot of domestic medias are called the stem cell) ,To replace the original hepatocyte. Plant these cells into the liver support again, and then the scientist will put this liver into a bioreactor, it is nutrient liquid to offer the constant-rate if flow for whole organ and special instrument of the oxygen. After staying in the bioreactor for one week, the scientist verifies it basically formed the human liver to organize, and produced the function correlated to it. At the beginning of this year, the scientist of U.S.A. Boston general hospital of Massachusetts state utilizes the similar support craft, graft and transplant into living mouse's body the mini mouse's liver, these mice survive for several hours.
