WebThe ultimate test for pluripotency has been the ability of mouse-cultured embryonic stem cells to contribute to chimeric (an individual, organ, or part consisting of tissues of diverse genetic constitution) tissues of the embryo after introduction of embryonic stem cells from several individuals into the preimplantation host blastocyst. WebJul 16, 2024 · In mice, functional oocytes can be produced from pluripotent stem cell–derived primordial germ cell–like cells (PGCLCs) by reaggregation with embryonic ovarian somatic cells at embryonic day 12.5. Therefore, in vitro gametogenesis is expected to be an innovative means of producing a robust number of oocytes in culture. prof henning walczak

WebFeb 15, 2015 · Relationship between development, cell potency and reprogramming. Development of a mouse begins with fertilization. 1-cell zygotes and blastomeres of 2-cell embryos are totipotent. The ICM cells in blastocyst are pluripotent. The transition from totipotent to pluripotent cells takes place between the 4-cell and morula stage. WebIn mice, only the zygotes and blastomeres from 2-cell embryos are authentic totipotent stem cells (TotiSCs), capable of producing all the differentiated cells in both embryonic and extraembryonic tissues and forming an entire organism1 . However, it remains challenging whether and how TotiSCs, representing the very beginning of a life, can be established …
