... resulting in a doubling of the cell number and a reduction in the cell size. At the 32- to 64-cell stage each cell is called a blastomere.2 The blastomeres stick together to form a tight ball of cells called a morula. Each of these cells retains totipotential. The next stage is the blastocyst ...
