Gastrulation in Drosophila: the logic and the cellular mechanisms.
The egg contains a set of molecules that can be used to trigger cell-shape changes leading to morphogenetic movements. The temporally and spatially controlled activation of these molecules, and hence the choreography of gastrulation movements, is determined by region-specific expression of transcription factors which turn on a set of downstream targets whose products mediate the successive steps of gastrulation.
