Four-cell mouse embryo, confocal microscopy and 3D virtual embryo processing. The blue cells, each called a blastomere, have divided from a single fertilised cell (zygote). Even at this early stage of development the cells are beginning to differentiate into those that will form the foetus and those that will form the placenta. The red cell is a polar body, formed during maturation of the egg cell. | |
