Scientists from the Department of Regenerative Medicine at the Japan Medical University successfully developed the monkey's cell tissue. This study has taken the human realization of the "animal organ factory" dream one step forward. The recent Japanese Yomiuri Shimbun website reported this important progress. Since the invention of embryonic stem cells and induced pluripotent stem cells (iPS cells), people have seen a bright future for regenerative medicine. However, with the current state of the art, stem cell and induced pluripotent stem cells are not effective in producing liver cells and pancreas cells, and it is difficult for the products to reach the level of stereotaxic structures of real organs. As a result, people began to use alternative approaches and began to try to use human embryonic stem cells and induced pluripotent stem cells to cultivate human organs and tissues that can be used for transplantation in animals such as livestock. This is the origin of the “animal organ factoryâ€. The use of "animal organ factory" products not only solves many medical problems, but also more importantly avoids ethical issues. Therefore, people are given high hopes. However, this study has not been a breakthrough because of the strong rejection caused by transplantation of cells between different types of animals. This time, Japanese scientists chose goat embryos that have not yet fully developed the immune system as their receptors, and they will develop monkey embryonic stem cells from various organs and transplant them from multiple locations into the embryos of the ewes. Scientists have found that organ tissues with a maximum diameter of 20 to 30 cm in lambs produced by ewes contain monkey-like nerve cells and cartilage as well as hepatocytes. This organ, which is similar to monkey organ tissue, is estimated to survive for more than a year. In this way, for the first time, Japanese scientists succeeded in cultivating “hybrid†animals between different species of large animals without using immune system inhibitors, which greatly promoted the research of “animal organ factoriesâ€. The researchers said that this study selected sheep as a receptor because the combination of human cells and sheep cells had a high difference in the mixed cell experiments, that is to say, it was more adaptable to binding and the effect was better than that of dogs and mice. Pigs, rabbits and other animals. At present, the biggest topic of the study is how to avoid causing infections among mixed animals. Scientists said that in the future, induced pluripotent stem cells may be used to solve this problem. Barbecue wire Grill Grate is made of high quality 304 stainless steel, never rusting and durable.
