cleavage stage [FBdv_00000054]
Stage during which the nucleus of the fertilized egg performs 13 rapid divisions, prior to cellularization (Hartenstein, 1993; Campos-Ortega and Hartenstein, 1997). The first seven divisions are synchronous (Campos-Ortega and Hartenstein, 1997). During the course of the subsequent three divisions, most of the nuclei approach the surface and then divide asynchronously a further three times, bringing the total number of cells to around 5000 (Campos-Ortega and Hartenstein, 1997). This corresponds to embryonic stages 1-4 (Hartenstein, 1993).
