Three and a half days after division begins (in mouse embryos), the proliferating cells form a structure called a blastocyst. It is 100 to 150 micrometers wide, or roughly the same size as the egg ...

Figure 1: Genes governing the development of the preimplantation mouse embryo. Most gene-expression studies have so far pointed towards changes in Tr gene expression during blastocyst dormancy or ...

Depending on the model, the Columbia team discovered that blastocyst complementation restored distinct mouse olfactory neural circuits. In contrast to the killing model, the rat neurons formed ...
