@t_rayon@azziChiA Excellent review! I'm interested in your perspective on intrinsic vs. extrinsic signals in differentiation within interspecies chimaeras. Do you believe these differences could significantly hinder the creation of chimaeras between taxonomic orders such as pigs and humans?
Amazing work by Beddington medal winner Guillermo Serrano Najera who showed how to reshape the primitive streak by altering the sources of signalling molecules. This offers new inights into how extraembroynic constraints shapes gastrulation movements. #BSCBDB22. #evolution
