Colorized scanning electron micrograph of a a grain of pollen from a peony plant. Peonies are herbaceous plants native to Asia, Southern Europe and Northern America.

Colocalization of the microtubule anchoring factor LL5α (red) with integrin α6 (blue) in the basal cortex of outer epithelium of mouse mammary gland tissue, and laminin (green) in the basement membr...

During division new basal bodies develop accessory fibers and begin to move apart to take up a position equidistant between the older complexes. The new kinetodesmal fiber seems to be associated with ...

Colocalization of the microtubule anchoring factor LL5α (red) with integrin α6 (blue) and laminin (green) in the epithelium of mouse small intestine. LL5α is localized to the basal cell cortex atta...

Electron micrograph of corn stunt spiroplasma (CSS) in the wall of the filter chamber (part of the alimentary canal) and in the hemolymph of a vector leafhopper D. gelbus. Note the mainly pleiomorphi...

Fibers that splay out from a mid piece pass to the pellicle. TEM taken on 4/5/71 by R. Allen with Hitachi HU11A operating at 75kV. Neg. 10,250X. Bar = 1µm. Published and adapted with permission from ...

The spasmoneme contains membranous tubules that are known to store calcium (see Favard, P. and N. Carasso, J. Microscopie 3:671-696, 1964) and to be modified ER. The alveoli only partially surround th...

Fibers that splay out from a mid piece pass to the pellicle. TEM taken on 4/5/71 by R. Allen with Hitachi HU11A operating at 75kV. Neg. 10,250X. Published and adapted with permission from J. Cell Biol...

Non-contractile stalk showing the striated nature of the fibrous “straws.” TEM taken on 6/12/69 by R. Allen with Philips 300 operating at 60kV. Neg. 3,570X. Bar = 2µm. A print of the negative wa...

Schwann cells in peripheral nerves secrete a layer similar to the basal lamina called the lamina externa, boundary layer, or basement membrane. In this micrograph, the lamina externa surrounds the Sc...
