The foreign expert of the Chinese Academy of Sciences succeeded in drawing and inducing the multi-functional stem cell
Cable of June 12 of Guangzhou of China News Service (red duckweed of Yang Wei's bright red) The reporter knows from biological medicine and research institute of the health in Guangzhou of the Chinese Academy of Sciences on the 12th, the scientific research experts of this institute discover, the kidney tube cells in the human urine are one of the ideal sources of inducing the multi-functional stem cell, because its preparation method is simpler than other methods, and high in quality. This research results are 21 researchers led by biological medicine and foreign scientist MiguelEsteban doctor of the research institute of the health in Guangzhou of Chinese Academy of Sciences, it took more than 8 months to study and finish. They have found and utilized the kidney tube cells in urine to succeed in inducing it as the multi-functional stem cell method finally. MiguelEsteban shows, this kind of technical operation is good, multi-functional stem cells of induction produced demonstrate that well differentiates ability. This is called <> is in " JournaloftheAmericanSocietyofNephrology ephrology " on June 3 (society's magazine of American kidney) Have and issue online. Nowadays, since induce multi-functional stem cell's technology to appear, the researchers from all parts of the world are all researching and developing this technology, it is multi-functional it not only has embryo's stem cell, but also involve the human ethics problem, to regenerated medical science, there is inestimable potential value. At present, a lot of cell tissues of the human body can be succeeded in inducing and becoming the multi-functional stem cell, for example the becoming fibrous cell, cutin cell, neural stem cell, amniotic fluid cells, blood cells,etc. of skin, but which kind of tissue cell has the best source, there is not a final conclusion yet at present. As to this, MiguelEsteban explain claim sometimes in some dermatosis or hemophilia, AIDS,etc. of having on the patient, disease of blood, may not necessarily become from their skin that extract and induce the stem cell in fibrous cells or blood cells, because these cells of theirs may be unhealthy. Therefore, they begin to look for other methods to obtain, lighten the unnecessary agony for the patients. It is 20 crowds to 30 -year-old different complexions that they have selected 13 ages at random, isolate the urine cells of the tube cell coming from the kidney from their urine, spend it after the culture medium cultivation of leather cell at the kidney, and then by guiding the source factor outside four kinds into urine cell of the persons who will support of these 13 against the method to duplicate the virus and infect, in 16 to 25 days, the cloning of embryo's stem cell kind appears, clone these to choose out continuing training, get the steady multi-functional stem cell of induction finally. In order to determine whether the multi-functional stem cell of the urine cell source has good division ability, MiguelEsteban differentiates urine cells to three germinal layer orientation, it is ectodermic neuronal cells respectively, mesoblastic myocardium cells, and entodermal hepatocyte. Appraised by the experiment, these myocardium cells splitting up have electric potential of movements and calcium that flow, prove it has physiological function. MiguelEsteban say, go on more direct technical operations that induce with urine, need first toilet at the patient only, its range of application is wide, can prevent other methods from producing a great deal of questions, and it is one of the regular detection means in clinical examination to gather the urine, may provide the chance to obtain the multi-functional stem cell's model of disease for more patients. MiguelEsteban still emphasizes, possesses the ability to live again constantly because of the renal tubule, it is except that it induces the multi-functional stem cell to convert to, still can change into other cell types, and is used in the tissue to rebuild, so in the near future, the man-made organ is not possible.
