A wave spreading around the blastoderm margin and then up the primary body axis is shown at 50x real time. The wave begins on the right side of the marginal zone. The movie represents a 30-sec integr...

Imaging sequence of calcium waves spanning from late shield state to 95% epiboly. This sequence covers 3 h of development and is running at 150x real time.The movie represents a 40-sec integration wi...

Imaging sequence of calcium waves from 95% epiboly to 12-somite state. Note that bidirectional waves predominate throughout this sequence. The waves in the latter two thirds of the sequence originate ...

Three calcium waves propagating around the blastodisc margin. This sequence covers 28 min of development around 90% epiboly.The movie represents a 30-sec integration window moving in 5-sec steps, run...

Calcium and Cleavage Furrows. Fertilized zebrafish eggs were collected within 5 min of spawning, enzymatically dechorionated, and injected with approximately 0.9 nl of a 1% solution of recombinant f-...
