Toxoplasma gondii expressing EGFP tagged Tgbeta1-tubulin and TgAPR1-mCherry (TgAPR1 is a Microtubule Organizing Center protein). Images overlaid with DIC. For GFP, ex 450-490 em 500-540; for mCherry...

Nuclear envelope and spindle dynamics when the nucleus moves into the neck of kar9delta mutant cells arrested in S phase. Movie plays at 100x real time and is movie S5 in Proc Natl Acad Sci. 2009. 106...

Primary rat hepatocytes in culture fixed and stained for beta-tubulin. The microtubules form a network throughout the cytoplasm. In this image they are seen originating from a brighter and denser re...

Details of the binding of the carrier vesicle to a microtubule. Four bridges, thought to be cytoplasmic dynein arms, span the 40nm space between these two structures. The membrane of the vesicle has b...

A high resolution micrograph of the monokinetids (single somatic basal bodies) of Coleps hirtus bear an anteriorly directed striated fibrous kinetodesmal fiber and a posteriorly directed ribbon of pos...

The monokinetids (single somatic basal bodies) of Coleps hirtus bear an anteriorly directed striated fibrous kinetodesmal fiber and a posteriorly directed ribbon of postciliary microtubules that arise...

An image of the transition from basal bodies to cilia within a portion of one of the oral membranelles of Euplotes. Parasomal sacs occur between the rows of basal bodies although these endocytic ports...

A high resolution of an oblique section of the Coleps contractile vacuole pore revealing the supporting microtubules and adjacent fibrous layer. Standard glutaraldehyde fixation followed by osmium tet...

A segment of the edge of the axoneme showing the outer axonemal dynein arms that extend from the A-subfiber of a doublet to bind to the B subfiber of the adjacent doublet. TEM taken on 4/21/88 by C. S...
