Purple sea urchin embryos undergoing mitosis. Embryos are expressing GFP-rhotekin GTPase binding domain, which is a probe for active Rho, with 3xmCherry-Ensconsin (a microtubule asociated protein sho...

Transmission electron micrograph of cell division in an insect spermatocyte captured in late anaphase - telophase with cytokinesis in progress. The homologous chromosomes appear as darkly stained disc...

This is a region of a (semithin) longitudinal section of onion root taken from the meristematic zone; this is the undifferentiated region of plant tissue from which new cells are formed. Therefore, it...

Confocal micrograph showing a dividing cancer cell (HeLa) in time-lapse. Cellular structures have been visualised in cyan (cell membrane) and red (DNA). The spiral arrangement captures the journey of ...

Dual-channel spinning-disk confocal time-lapse movie showing anaphase relative to poleward microtubule flux. Fluorescent speckle microscopy (FSM) of microtubules was performed as described in Maddox e...

16-cell purple urchin embryo expressing three tandem GFPs fused to the ensconsin microtubule-binding domain (EMTB-3G; Faire et al., 1999). The embryo was treated with 40 µM trichostatin A (TSA), an ...

High resolution of a daughter micronucleus in anaphase of a dividing cell of Didinium nasutum. The chromosomes are compacted into one large heterochromatic body. Remnants of the mitotic division spind...

Microtubules in sand dollar embryo expressing three tandem GFPs fused to the ensconsin microtubule-binding domain (EMTB-3G; Faire et al., 1999). Eight-cell sand dollar embryo; single microtubules gro...

Eight-cell purple urchin embryo expressing three tandem GFPs fused to the ensconsin microtubule-binding domain (EMTB-3G; Faire et al., 1999). The embryo was treated with 20 µM nocodazole at time 00:...

One of eight cells in a slightly compressed sand dollar embryo expressing three tandem GFPs fused to the ensconsin microtubule-binding domain (EMTB-3G; Faire et al., 1999). The embryo was treated wit...
