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...

The movie illustrates two approaches to understanding the 3D structure of complex objects, using the pluteus stage embryo of the sea urchin Arbacia punctulata. The first sequence is a through-focus DI...

The video shows a cytoplast that is adhering to a sub-stratum in its central portion. It is also connected by a retraction fiber to its central cell. The cytoplast is engaging in vigorous protrusive a...

The video shows epidermal cells at the edge of an epithelial sheet in culture. There is vigorous lamellipodial activity at the edge of the cell cluster. Lysosomes and elongated mitochondrial are seen ...

Movie of anaphase A and B of meiosis I in primary spermatocytes of the crane-fly Nephrotoma suturalis. Time-lapse DIC microscopy using a Nikon Microphot SA, equipped for liquid crystal polarized lig...

Phagocytosis of injected live E. coli and B. subtilis by early macrophages in the yolksac blood circulation valley; real time. A macrophage loaded with B. subtilis bacteria now phagocytoses an erythro...

Video showing Vorticella (bell-shaped protozoans), ciliates attached to filamentous alga. The myoneme within the stalks contract with one of the fastest known movements in nature. Images were collecte...

Paramecium multimicronucleatum - Video of the Contractile Vacuole Complex. In vitro CVC rounding/relaxing cycles. An in vitro CV in a ruptured Paramecium cell is surrounded by cytoplasmic vesicles and...

Paramecium multimicronucleatum - Video of the Contractile Vacuole Complex. Effects of applying suction to an in vitro CV. Effect of suction on the rounding/relaxing cycle of an in vitro CV of Parameci...

Time-lapse movie of a human tumor fragment grown in Matrigel that was freed and reembedded in Matrigel. Images collected every 15 minutes and bar is 50 microns. CIL 42162 (this movie) - CIL 42165 a...
