The lateral line primordium is a slug-like mass of cells that crawls down the flank of the fish, leaving clusters of cells that will form the lateral line neuromast organs. Elapsed time indicated by t...

Primary endothelial cells from transgenic mouse embedded in 3D collagen gels of ~ 100 Pa Young's modulus are exposed to 10 micromolar blebbistatin (myosin II ATPase inhibitor). Phase contrast time lap...

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...

Video illustrating the speed of breast cancer cell movement. Cancer cells can move as fast as 200 µm/hour through very small channels. This video shows the breast cancer cell line MDA-MB 231, moving...

This confocal image shows a 13.5 days post coitum female mouse gonad at high magnification (x40). The developing ovary and mesonephros were fluoresently stained with an endothelial and germ cell marke...

Short timelapse movie of prechordal plate, hypoblast, and yolk syncytial layer (YSL) nuclear movements during 80-90% epiboly. The prechordal plate and notochord can be seen as a tighter clump of cells...

Individual Mouse Aortic Endothelial Cell (MAEC) migrating in a 3-dimensional collagen gel (1.4mg/mL). Imaged on a spinning disk confocal microscope using a 100x oil immersion objective lens on a Nikon...

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...

Dynamics of Cellular and Syncytial Endoderm. An ectopic embryonic axis was induced by injecting a marginal blastomere of a 32-cell stage embryo with TARAM-A (Tar*, a receptor for Nodal-like ligands) R...
