Zebrafish embryo at the 5-somite stage The cross-sectional view is in the ventral portion of the neural keel. In the lower portion of the image, somites detach from ventral mesoderm. Oriented division...

Tetrahymena cells that are not forming a digestive vacuole often have a tube-like extension of the cytopharyngeal membrane attached to the deep fiber that extends several microns into the cytoplasm. T...

Confocal micrograph of astrocytes and oligodendrocytes from neural stem cells Astrocytes (green) and oligodendrocytes (red) derived from rat neural stem cells in culture. Both these cells are types of...

Scanning EM of a 24 hr (prim-5) Zebrafish embryo, showing the fibrous extracellular matrix connecting the mesoderm to the migrating neural crest cell. Specimens were chemically fixed critically poi...

Dominant features of a nephron in the cortex of rat kidney showing f-actin localization in the glomerulus, a blood vessel, and proximal tubules. The glomerulus is the large ball at the left. The blo...

Confocal micrograph of neural stem cells transplanted into mouse brain Mouse neural stem cells, labelled with green fluorescent protein, have been transplanted into the brain of a newborn mouse and ar...

Astrocyte cell from live slices taken from the cortex layer 2/3 of an 8 month old GFAP mouse. In this mouse the enhanced green fluorescent protein (EGFP) under the control of the human glial fibrilla...

Human spinal cord neurosphere (a culture system composed of free-floating clusters of neural stem cells) captured with widefield Illumination and deconvolution. Honorable Mention, 2005 Olympus BioScap...

A colorized scanning electron micrograph of a human egg, which is the huge cell colored yellow at the bottom of this image. The follicle cells that surround it (top) send out long projections that pen...
