Polymerized actin localization in wild type Arabidopsis thaliana leaf trichomes, stage 4, during the transition to branch elongation. Detailed methods: Intact Arabidopsis shoots were fixed in 100 mM P...

Figs. 314 from Don Fawcett's Chapter 12 (Centrioles). At the base of the flagellum of a mammalian spermatid, the juxtanuclear proximal centriole is continuous (at the arrow) with a structure of simila...

Polymerized actin localization in arpc2/distorted2 mutant Arabidopsis thaliana leaf trichomes during the transition to branch elongation. The "distorted group" of trichome morphology mutants were or...

Polymerized actin localization in wild type (left) and mutant (right) Arabidopsis thaliana leaf trichomes during the transition to branch elongation. The "distorted group" of trichome morphology mutan...

Four cell stage zebrafish embryo, stained with 100 micromolar Bodipy 505/515. In the upper portion of the image, the yolk cell contains large spherical yolk platelets. The blastomeres undergoing merob...

Zebrafish Embryo, from tailbud to 16-hour stage, stained with 100 micromolar Bodipy-Ceramide. Bodipy-Ceramide permeates the enveloping layer epithelium of the embryo, accumulating in the interstitial ...
