High resolution overview of Coleps hirtus cell seen in this median transverse section. This barrel-shaped cell has a few rows of cilia and the cell is covered with calcified polysaccharide platelets t...

10 Tailbud pulses over 105 min at 8-12 somite stages. This is the latter part of the 95% epiboly to 12-somite sequence flipped vertically for clearer orientation. The movie represents a 120-sec int...

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

This movie shows the "yolk flash". The apparently whole-embryo calcium pulse appears to initiate over a widespread area of blastoderm, possibly earliest at the animal pole, and then spreads first to ...

Prewave pulse and axial wave. This prewave pulse appears to arise predominantly from the animal pole region, others however appear to emerge nearly simultaneously over large regions of the blastoderm...

Pre-wave pulse (PWP). The apparently whole-embryo calcium pulse appears to initiate (the PWP region on the wave graphs) over a widespread area of blastoderm, possibly earliest at the animal pole, and...

Overview of Coleps hirtus cell seen in this median transverse section. This barrel-shaped cell has a few rows of cilia and the cell is covered with calcified polysaccharide platelets that are housed w...

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-...

A single bidirectional calcium wave. The prewave pulse lasts only for 0.6 sec in this time-lapse sequence. This sequence covers 350 sec of development at 50x real time. The movie represents a 30-sec...

A unidirectional calcium wave arising form the left side. The wave originates from a hot spot on the left side of the blastoderm margin and intensifies while crossing the node region. This sequence ...
