C. elegans and C. briggsae. These worms are closely related, and both used for research. Image from Wormbase.

Distal Tip Cell

Distal Tip Cell

Distal tip cell, the lower right irregular shaped cell, is a single somatic cell located to the tip of a C. elegans gonad. As a result, a hermaphrodite has total 2 distal tip cells, one on each end of the gonad. The cells adjacent to the distal tip cell in this image are germ cells. Please see the Kimble Lab website for more information. Distal Tip Cell by David Greenstein.

C. elegans germline

C. elegans germline

Isolated C. elegans gonad with the nuclei labeled. The distal tip cell would be located to the right most of the image. From the distal tip cell end to oocytes, there are germ cells in various states of maturation. Image courtesy of the Schedl Lab.

Early embryonic development (metaphase in mitosis) over time, from upper left to lower right with tubulin (microtubules) labeled, showing the elongation of the mitotic spindle prior to the first cell division. Courtesy of Ahna Skop, Skop Lab.

DAPI staining

DAPI staining

A C. elegans with nuclei (DNA) labeled (DAPI stained). Each colored spot (light blue) represents a cell of the C. elegans.

Spermatozoa

Spermatozoa

Matured C. elegans sperm cells (spermatozoa) by scanning electron microscopy (SEM). The knobby projections to the right of the cell are called a pseudopod, which the cell uses to crawl. See also TEM (Transmission Electron Microscopy) image of C. elegans sperm cells.
