C. elegans Early Embryo Development

Tim Walston

This PowerPoint lecture describes C. elegans early embryo development. It also includes detailed description about C. elegans gastrulation.

Cell Lineage

Fong-Mei Lu

The embryonic cell lineage of C. elegans from zygote to hatched larva provides an excellent tool for learning fundamental principals in developmental biology.

Using Digital Microscopy

Madelaine Travaille and Sandra D. Adams

Travaille, M. & Adams, S. (2006). Using digital microscopy. The Science Teacher. 73(4), 50-54.

In this article, video digital microscopy was used that allowed students to capture images of C. elegans [both time-laped and still] to study animal behavior and development.
