The precise coupling of f-actin and parallel MT movements occurrs in all four zones of f-actin dynamic behavior: the lamellipodium,lamellum, convergence zone, and cell body. Primary cultures of newt ...

Four general zones of f-actin movement are seen in primary cultures of newt lung epithelial cells microinjected with X-rhodamine actin. At the leading edge and throughout the lamellipodium, f-actin s...

A confocal Z-stack of neurons in postnatal hippocampus, expressing a GFP-tagged knockdown construct for the microRNA miR-137 (green, sh-miR-137) and immunostained to localize doublecortin (red), a mar...

The JNK phosphatase puckered, whose expression can be reported via a lacZ enhancer trap, is expressed in very low levels in uninjured neurons; however, nerve crush induces a dramatic increase in puc-l...

A confocal 4D-stack from a transgenic Drosophila embryo during prometaphase expressing lamin-GFP (green) and injected with rhodamine-conjugated tubulin (red) and the lamin-B tail dominant negative sub...

Apoptotic cells produce and transmit the bioactive lipid sphingosine-1-phosphate (S1P) during extrusion. This set of images shows that extrusion is blocked, as well as accumulation of S1P around the d...

Sub-confluent, interphase Human Umbilical Vein Endothelial Cells (HUVECs) transfected with GFP-WT-MCAK (Mitotic Centromere Associated Kinesin) and grown in culture for 8 hours. Cells were fixed in PH...

Spinning disk confocal time-lapse imaging of the first mitosis in a C. elegans embryo expressing GFP-KNL-2 in which CeCENP-C was depleted by RNAi in strain OD31. Discrete foci of GFP signal within the...

Mitotic PtK1 cell microinjected with X-rhodamine-labeled tubulin and Alexa 488-labeled CENP-F antibodies to fluorescently label kinetochore fibers (red) and kinetochores/spindle poles (green), respect...

The JNK phosphatase puckered, whose expression can be reported via a lacZ enhancer trap, is expressed in very low levels in uninjured neurons; however, nerve crush induces a dramatic increase in puc-l...
