Developmental Biology
C. elegans Structures: high (20X60) magnification
Adult male, protruding
Same as previous, with different focal plane highlighted
At left: L3 male with slightly less developed tail. The animal on the right is L4 male with more developed tail.
Male animal: Fan, hook, half of the body
Worm beta-gel lab
Staining transgenic worms for ß-galactosidase. Also includes a list of supplies and solutions required for ß-galactosidase staining lab.
C. elegans Early Embryo Development
This PowerPoint lecture describes C. elegans
early embryo development. It also includes detailed description about C. elegans gastrulation.
Cell Lineage
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
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.
