Hela cells transiently transfected with EGFP-GL-GPI show the organization of the membrane thru the distribution of GPI anchored protein. This image is the maximum z projection image that accompanies...

Actin dynamics in a Rac1(Q61L)-expressing PtK1 cell injected with Pak inhibitory fragment PBD/ID(H83L). Fast retrograde flow still occurs in the lamellipodium, but the width of the lamellipodium is re...

Movie shows spindle assembly around DNA-beads in a Xenopus laevis egg extract. DNA beads are autofluorescent, and spindle is formed from exogenous X-rhodamine-labeled tubulin. By the end of the movie...

The events of meiosis I in a living insect spermatocyte beginning at metaphase with bivalents at the spindle equator, followed by anaphase onset, chromosome segregation and the start of cytokinesis. T...

Figures 206 (upper) and 207 (lower) from Chapter 6 (Golgi Apparatus) of 'The Cell, 2nd Ed.' by Don W. Fawcett M.D. During development of the acrosome in the chinchilla spermatid, the transitional zon...

The distribution of the mitochondrial inner membrane protein mitofilin, visualized here with antibody to mitofilin , highlights the very long tubular morphology of mitochondria in mouse 3T3 fibroblast...

Living Lilium pollen tube imaged with DIC optics. Shown is the growing tip with the apical region devoid of cytoplasmic organelles. Other images in the group reveal the distributions of cytoskeletal ...

HeLa cells were processed for indirect immunofluorescence with antibodies to two nuclear pore components, ELYS (embryonic large protein derived from yolk sac) and mAb414 against the FG nucleoporins. B...

Didinium captures Paramecium. Paramecium is almost completely ingested and the proboscis is beginning to reform. This micrograph was taken in 1968 by G. Antipa on a Cambridge Mark IIA operating at 20k...

Confocal image of an axonal rainbow of oculomotor nerve motor axons from a "Brainbow" mouse brain, with each neuron expressing a distinct color. In Brainbow mice, neurons randomly choose combination...
