The scientist of our country cultivates pigs " Omnipotent" Stem cell
It is reported ' Reporter Hu DeRong) The Xiao 's of research institute of Shanghai life of Chinese Academy of Sciences utilizes the cultivating as body cells of the pig " Omnipotent" Stem cell, this cultivates the family and raises the multi-functional stem cell of ungulate's animal in the world for the first time too. This research results are published in the international scientific periodical " biological journal of molecule cell " online recently. It is introduced, scientific research personnel, through using the transcription factor to value the cells from ears and bone marrow of a pig of programming, succeed in cultivating and inducing the multi-functional stem cell; And then to introduce mixture of these heavy programming factors in cells through a kind of virus, make these cells change, and development has become group of one kind of stem cells of embryo. Further test proves, they really have the ability to divide into three layers (entoderm, mesoblastic and ectoderm) which make up the embryo Cell type,here all embryo's stem cells have ability. It is reported, researchers can revise the gene of pig in the stem cell, and cultivate the pig which carry the likewise genetic obstacle, thus let them have with human patient's similar symptom, then may use this kind of pig's model to develop and treat the treatment of this kind of disease.
