Progress of interspecies chimeras and their potential applications
Journal Title: Biomedical Transformation - Year 2022, Vol 3, Issue 4
Abstract
Interspecies chimerism based on pluripotent stem cells is the frontier of modern biology research and one of the main techniques to solve the worldwide dilemma of organ shortage. Stem cells with different states of pluripotency and developmental potential are microinjected into preimplantation blastocysts, which can contribute to embryos or extra-embryonic tissues, and then produce tissues and organs partly or completely developed from stem cells. It makes in vitro generation of functional human organs for transplantation theoretically possible. This article systematically reviews current progress in interspecies chimeras in mammals (mainly rodents and primates), explores technological barriers and ethical challenges, and envisions the future directions in interspecies chimeras research, and hopes to provide new ideas and means to solve the serious shortage organs for transplantation.
