Researchers at the university of Hong Kong have successfully created new stem cells
Using human skin cells, researchers at the university of Hong Kong have successfully created stem cells that can be transformed into cells and tissues from various human organs, the university said on 13th. This will help to study the development of diseases such as cardiovascular disease and progeria.
Researchers at Hong Kong university's li ka-shing school of medicine created the "artificially induced universal stem cell" by using an enzyme inhibitor to stimulate stem cell recombination, transforming human skin cells into a state similar to embryonic stem cells, it was reported. Because the new stem cells share the same genetic makeup as the donor, they are free of rejection problems and avoid the ethical controversy associated with using human embryonic stem cells. In addition, the production process does not involve animal living cells and serotonin and other components, which is conducive to human clinical application.
In addition, the researchers used by "artificial induced pluripotent cells" derived "mesenchymal stem cells", transplanted to the limb function is damaged due to blood vessels and lead to damage of mice, and found that "department of mesenchymal stem cells can form new blood vessels, improve blood circulation of rats, this is expected to provide more effective treatments for a variety of cardiovascular diseases.
Science professor at Hong Kong Xie Hongfa said, "artificially induced pluripotent cells into different tissue cells, including the heart, brain, blood vessels, kidney, etc., provides an unlimited source of human cells, let the doctor easier to study the evolution of the disease process, such as premature aging disease, as well as direct reagent on cells in a petri dish typically increases in these cells.
