Confocal micrograph showing the complex connectivity at the neuromuscular junction of Drosophila (fruit fly). Muscle fibers shown in red and nerve fibers into neruomuscular junction shown in blue and ...

Time series of cooled CCD fluorescence micrographs of live amoeba syringe-loaded with Rho-N58C-PII. See publication below for details. Live cells were observed with a Zeiss Axiovert 135 fluorescence m...

The proteasome is a large, highly conserved protein complex whose main function is to enzymatically degrade target proteins. The eukaryotic proteasome houses six protease sites that are located deep w...

Figure 205 from Chapter 6 (Golgi Apparatus) of 'The Cell, 2nd Ed.' by Don W. Fawcett M.D. Sequence of the development of the acrosomal cap in spermatids from guinea pig testis, as observed in electro...

The distribution of mitochondria (labeled with antibody to heat shock protein 70) in relation to intermediate filaments (labeled with vimentin antibody) 16 hours after release from serum starvation in...

Views of a striated band linked to the epiplasm on the ridge slopes and the intermembrane space between the plasma membrane and alveolus space inside the alveolus. TEM taken on 6/6/91 by C. Schroeder ...

Transmission electron micrograph of adherens junctions (macula adherens or desmosome)in the proximal tubule of a rat kidney. The junctions with associated tonofilaments are seen at the apposed plasma...

Transmission electron micrograph of tight junction (zonula occludens) between adjacent plasma membranes in the distal kidney tubule. The darkly staining horizontal structure forms the junctional compl...

The events of meiosis I and II in a living insect spermatocyte beginning with the breakdown of the nuclear envelope at diakinesis through to the completion of cytokinesis. Testes from the Crane fly N...

The events of meiosis I in a living insect spermatocyte beginning at metaphase with meiotic bivalents at the spindle equator followed by anaphase , segregation of bivalents to the spindle poles and t...
