An anucleate cytoplast--a piece of lamellipodium detached from its parent cell--is able to migrate autonomously, without a nucleus, Golgi Apparatus, or microtubules. Image made available thru Mark Coo...

This video shows stationary epidermal cells with copious retrograde flow of actin. Actin-myosin networks initiate at the cell periphery and flow towards the cell body. Even though actin-nucleation and...

This video shows a cytoplast in the process of forming. Early in the sequence the cytoplast is still attached by a retraction fiber to its parent cell. As the retraction fiber breaks, the cytoplast is...

A 2.75 hour Zebrafish embryo; the same embryo as in CIL 37403 --later in blastoderm development. The video shows dynamics in a perisagital section of the embryo. The sequence shows blastomeres dividin...

Timelapse of dorsal side during gastrulation shows migration of hypoblast and underlying yolk syncytial layer (YSL) nuclei (larger bright spots). The prechordal plate can be seen as a more clumped mas...

Timelapse of dorsal yolk syncytial layer (YSL) nuclei and blastoderm morphogenesis from sphere stage (late blastula) to 1 somite stage. Top panel shows Nomarski movie of blastoderm morphogenesis inclu...

A 4D visualization of zebrafish somitogenesis and neural keel formation. The Quicktime movie shows progressively dorsal optical sections in a segmenting embryo. Note the midline alignment of neuroepit...

This video shows an epidermal cell loaded with a florescent lipid diOC-6. diOC-6 is a vital stain for the endoplasmic reticulum and mitochondria. In this sequence one sees the extension of ER tubules ...

This is a migrating epidermal cell showing vigorous lamellipodial ruffling more than 180 degrees around its circumferance. The cell becomes elongated into a canoe shape. The mechanical tension generat...

This sequence shows actin nucleation on the dorsal surface of an advancing lamellipodium. Small actin nucleations have been termed inductipodia in nerve growth cones, since they can be induced by late...
