Movie of portion of a hypermastigote symbiont from the hindgut of a wood eating cockroach. The rootlets and flagella are birefringent and the beating flagella are clearly seen with the polarizing micr...

The movie shows the wave-like effect of compensated birefringence caused by rotating spirochetes attached to the surface of a hypermastigote protozoan. The image was obtained using a rectified polariz...

Sand dollar embryos expressing GFP-H2B going thru stages of mitosis.

Leishmania mexicana amastigote forms (WHO strain MNYC/BZ/62/M379). Amastigotes were grown in axenic culture. The cells were fixed with glutaraldehyde, dehydrated in ethanol, critical-point dried and s...

The image shows a developing Drosophila spermatid immunostained for caspase activity (green). TRITC-phalloidin is used to label actin (red). Caspase is required in spermiogenesis for the elimination ...

A scanning electron microscope image of an activated mast cell illustrating the convoluted topography of the cell membrane, which is populated with receptors.

Phase contrast microscopy of purified liver sinusodial endothelial cells (LSECs) from Brown Rat.

Fenestrae of a Brown Rat arranged in sieve plates. Original magnification is 20,000x, a good indication of liver sinudosial endothelial cells (LESCs).

Confocal image of a Xenopus laevis egg imaged at 119 min post fertilization. The embryos are stained for alpha-tubulin (green) and gamma-tubulin (red).

Scanning electron micrograph of red blood cells clearly showing their biconcave disc shape. Human red blood cells are typically 8 microns x 2 microns in size.
