Human Kidney Successfully Grown..! Chinese Scientists Grow Human Kidneys Inside Pig Embryos, Paving the Way for Organ Transplants In a remarkable breakthrough, Chinese scientists have achieved a major milestone by cultivating kidneys that contain human cells within pig embryos. This groundbreaking research, disclosed in a study published in the journal Cell Stem Cell, offers a promising solution to the pressing shortage of organs available for transplantation.
The research, conducted at the Guangzhou Institutes of Biomedicine and Health, targeted kidneys due to their early development and frequent use in human medical transplants. While previous endeavors have sought to grow human organs in pigs, this accomplishment marks a significant leap forward to Human.
The Challenge: Pig cells usually dominate human cells when coexisting. To overcome this hurdle, the research team turned to CRISPR gene editing, removing two critical genes necessary for kidney formation in pig embryos. This created a specialized environment known as a “niche. Before implanting these genetically modified embryos into surrogate mother pigs, they were cultured in test tubes containing nutrients for both human and pig cells. with total of 1,820 embryos were transferred into 13 surrogate mothers, and pregnancies in which terminated approximate 25 and 28 days to assessthe progress of the experiment. Promising Outcomes: Among the embryos selected for analysis, five exhibited normally functioning kidneys for their stage of development, including the beginnings of ureter growth, containing 50 or more human cells. Importantly, there were only minimal traces of human neural cells in the pig brains and spinal cords, and no human cells were identified in the reproductive tissue. This is a crucial factor, as uncontrolled mingling of human and pig cells in reproductive areas could lead to the creation of human-pig hybrids, raising ethical concerns.
Ongoing Challenges: While this research represents a significant achievement, it is not yet ready for human transplantation. One limitation is that the Human kidneys contained pig-derived vascular cells, which could trigger rejection if transplanted into a human recipient. The team’s objective is to refine their technology for Human Kidney Successfully Grown use, extend the kidney development period, and explore the feasibility of growing other human organs in pigs, such as the heart and pancreas. this accomplishment holds promise for alleviating organ shortages, but there are still obstacles to overcome before these lab-grown organs can be utilized in human transplants.
