In situ hybridizations showing the localization of bicoid (top), oskar (middle) and gurken (bottom) mRNAs in the stage 10 Drosophila egg chambers. These localizations define the anterior- posterior a...

Platinum replica illustrating the cytoskeletal organization of dendritic spines from extracted 14 DIV neurons. Thin spines associate with dendrites at the base (bottom) and with axons by the head (top...

Stack of time series images showing the change in microtubule distribution in cultured porcine kidney epithelial cells (LLCPK1) stably expressing GFP-alpha tubulin during the progression from prophase...

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...

Phase contrast micrograph of spore formation and release in Aspergillus, an ascomycete, using a semi-thin stained section stained blue. Chains of asexual spores (conidia) bud off from the projections ...

Time lapse movie of a porcine kidney LLCPK1 cell stably expressing photoactivable GFP-tubulin. Fluorescence was activated at metaphase in a vertical strip between the metaphase plate and spindle pole....
