Vietnam separates stem cells from mouse embryos

Associate Professor Nguyen Mong Hung and his colleagues from the Department of Biology, University of Natural Sciences (Hanoi) have succeeded in separating and cultivating long-term stem cells of mouse embryos, turning them into blood stem cells.

Dr. Hung said that in the past there were several domestic research groups claiming to be able to extract stem cells from mouse embryos, but there was no evidence. His research is clearly demonstrated, based on stem cell morphology, in directive and efficacy (saving irradiated mice longer).

Dr. Hung's team isolated stem cells from mouse embryos, and injected them into vesicles of high-irradiated mice. 30 experimental mice were irradiated at 800 to 900 doses - 100% lethal dose after a week, because radiation destroyed all red blood cells and red blood cells. However, when injecting stem cells for them, many live for more than 1 month. The test showed that the spleen of these animals appeared new hematopoietic drives, indicating that stem cells worked - transforming into hematopoietic cells to produce new red blood cells for mice.

Currently, because Vietnam does not yet have a legal framework for taking stem cells from human embryos, the research team stopped at animal works, such as chickens and mice. Because mice are mammals close to humans, this success is quite important, and will open new research directions on human embryonic stem cells in our country. Dr. Hung said his team intends to cooperate with the Ministry of Health to implement this topic, serving in medicine.

Previously, Dr. Hung's group has also succeeded in creating 26 evil chickens containing Luong Phuong chicken cells by embryonic stem cell technology.
