Important events in embryonic stem cell research and related fields in recent years

in recent years, embryonic stem cell research has made many important achievements, and experts have made progress in developing "pluripotent cells" similar to such stem cells2
200
March, the Whitehead Institute for Biomedical Research in the United States successfully carried out embryonic stem cell therapy in laboratory mice with cloning technology, the first time in animals to confirm that "therapeutic cloning" technology is feasible2
200October, The second affiliatedHospital of Zhongshan University, China, established the first Chinese embryonic stem cell line of the sacinset cell group developed from artificial fertilized eggs, making China one of the world's leading in this field2
April 2003, the Japan Institute of Physical Chemistry announced that the world's first use of monkey embryonic stem cells to produce two kinds of endothelial nerves, this achievement broadens the prospects for regenerative medicineIn May 2004, the world's first national embryonic stem cell bank was established in London, UK, and it provides,for research and treatment ofdiseases
such as diabetes,cancer,Parkinson's disease and Alzheimer's diseaseSeptember 2004,Massachusetts Advanced Cell Technologies announcedhas successfully developed aof retinal cells with human embryonic stem cells,technology that could be used to treat blindness caused by retinal degenerationOn January, 2005, experts at Kyoto University in Japan,, first reported that,they differentiated monkey embryonic stem cells into neural stem cells and implanted them into the brains of six monkeys with Parkinson's diseaseIn August 2006, Kyoto University in Japan announced that researchers at the University of Kyoto had used skin cells from laboratory mice to make "ploritoral cells" that could be differentiated into various tissues and organs, a result that laid the technical foundation for the use of human skin cells to "replicate" embryonic stem cells In November 2007, the Health and Science University in Oregon reported that they used skin cells and eggs from different macaques to grow embryos This is the first time that scientists have successfully cloned primate embryos In November 2007, experts at the University of Wisconsin and Kyoto University in Japan reported that they had transformed human skin cells into stem cells that could be almost comparable to embryonic stem cells, an achievement that is expected to ward off the ethical controversy that has long been faced, giving a major boost to stem cell-related diseases therapies
