Anterior and posterior regions of a C. elegans embryo are determined by PAR protein distribution. PAR-2, shown in green marks the posterior region of the embryo and PAR-6, shown in red, marks the ante...

Spinning disk confocal time-lapse imaging of the first mitosis in a C. elegans embryo expressing GFP-KNL-2 (strain OD31) in which KNL-1 has been depleted by RNAi. Discrete foci of GFP signal within th...

The retrograde flow of microtubules oriented perpendicular to the leading edge in the lamellipodium is coupled to the movement of immediately adjacent lamellum f-actin speckles. Primary cultures of n...

Free microtubule sliding in nip100deltaCAP-Gly cnm67delta double mutant cells. Movie plays at 50x real time and is movie S12. Compare with movie S11 (CIL# 23601). Data analysis for movies S11 and S12 ...

Early embryonic divisions in Drosophila are syncytial. Nuclei undergo mitosis synchronously for the first 14 nuclear cycles, followed by cellularization (Foe and Alberts, 1983). At nuclear cycle 10, n...

This movie is of a Drosophila melanogaster early embryo (cycle 12) expressing GFP-tubulin (green) and injected with Rhodamine-labeled histones (red) and 8mg/ml RanT24N, a dominant negative inhibitor o...

Co-expression of wild-type Arf1-GFP (Arf1(WT)-GFP) (gray) and inactive Src (SrcK-DsRed) (red) in Src-deficient SYF fibroblasts does not induce trafficking of Helix Pomatia Lectin (HPL) (green) from t...

YFP-Parkin (green) does not translocate to mitochondria (red) when HeLa cells are transfected with PARL (presenilin-associated rhomboid-like protein) siRNA. HeLa cells stably expressing YFP-Parkin wer...

YFP-Parkin (green) localizes to mitochondria (red) when HeLa cells are treated with the mitochondrial depolarizing agent CCCP (carbonyl cyanide-m-chlorophenyl hydrazone). HeLa cells stably expressing ...

An ER-trapped GalNac-T activity reporter (Muc-PTS; fused to GFP) (green) is targeted to the ER and not the Golgi, marked by Giantin (red) in HeLa cells cotransfected with active Src (SrcE-mCherry, con...
