摘 要:Blastocyst complementation by pluripotent stem cell(PSC)injection is believed to be the most promising method to generate xenogeneic ***,ethical issues prevent the study of human chimeras in the late embryonic stage of *** embryonic stem cells(ESCs),which have similar pluripotency to human ESCs,are a good model for studying interspecies chimerism and organ ***,whether primate ESCs can be used in xenogenous grafts remains *** this study,we evaluated the chimeric ability of cynomolgus monkey(Macaca fascicularis)ESCs(cmESCs)in pigs,which are excellent hosts because of their many similarities to *** report an optimized culture medium that enhanced the anti-apoptotic ability of cmESCs and improved the development of chimeric embryos,in which domesticated cmESCs(D-ESCs)injected into pig blastocysts differentiated into cells of all three germ *** addition,we obtained two neonatal interspecies chimeras,in which we observed tissue-specific D-ESC *** together,the results demonstrate the capability of D-ESCs to integrate and differentiate into functional cells in a porcine model,with a chimeric ratio of 0.001-0.0001 in different neonate *** believe this work will facilitate future developments in xenogeneic organogenesis,bringing us one step closer to producing tissue-specific functional cells and organs in a large animal model through interspecies blastocyst complementation.
