Project description
An out-of-the womb platform for mammals
ExUteroEmbryogenesis is an ambitious project funded by the European Research Council. The project is part of active scientific efforts to study mammalian embryogenesis while avoiding the use of humans for ethical reasons. It has two main ambitions. The first aim is to test a recently developed platform that allows growing mouse and rabbit embryos ex utero until the complete formation of organs. The second aim is to engineer synthetic embryos of additional mammals (non-human primates) from in vitro-induced stem cells. The project has numerous applications, including transplantation using induced pluripotent stem cells.
Objective
Studying early human development is crucial for understanding embryonic defects and learning developmental principles that can be applied in differentiation of human iPSCs into relevant cells for transplantation. Such research requires large numbers of human embryos, however justified ethical barriers makes this impossible. Since the mouse has been a guiding compass for all revolutionary technologies applied with human pluripotent stem cells, here we seek to develop biotechnologies in mice, rabbits and non-human primates (NHP) that will likely enable in the future, conceptually and technologically, circumventing this problem in humans.
A two-pronged biotechnological platform development will be pursued: 1)Engineering devices that enable ex utero culture of mammalian embryos from pre-implantation until complete organogenesis 2)Establishing platforms in which in vitro expanded stem cells can be coaxed to generate synthetic embryo-like structures (embryoids), that can self-organize and be grown in the latter developed ex utero embryogenesis devices, to yield structures with both embryonic and extra-embryonic compartments, that capture advanced embryonic patterns.
Motivated by our recently devised platform that allows natural mouse embryogenesis from post-implantation until organogenesis ex utero, we now aim to develop and validate biotechnological platforms that capture entire stages of development from pre-implantation until completion of organogenesis in natural mouse and rabbit embryos ex utero, and transform this knowledge to engineer advanced synthetic embryoids from in vitro expanded mouse, rabbit and NHP stem cell populations. We will utilize in-house engineered devices, stem cell-based models, cutting-edge gene editing, microscopy, optogenetics and single cell biology. Our work will establish novel platforms for generating advanced self-organizing embryoids ex utero, that can be used for stem cell differentiation, drug screening and disease modeling.
