摘要

The generation of organs derived from pluripotent stem cells can be achieved in vivo through the blastocyst complementation technique. This method is based on the introduction of pluripotent stem cells into organogenesis-disabled pre-implantation embryos, where environmental signals instruct donor cells to colonize the vacant niche and to develop into the missing organ. When applied interspecies, this approach has the potential to produce human organs in genetically engineered livestock, offering a promising solution to the global transplants’ shortage crisis. In this review, we summarize the current progress in blastocyst complementation research and highlight the key challenges that must be addressed to advance this field.
