no class – Thanksgiving Break
Also remember there are two, short writing assignments, each worth 20 points.
Pick any topic in developmental biology (except your term paper topic) and learn more about it. Then
write a two page paper and include all the sources you used (those can include any sources including web
sites, newspapers, TV, etc). These are due anytime.
Chapter 8: Morphogenesis
Morphogenesis involves:
extracellular matrix
cell adhesion molecules
cytoskeleton
Chapter 8: Morphogenesis
Morphogenesis involves: cytoskeleton, cell adhesion molecules, ECM
Major components of the cytoskeleton:
Microfilaments
actin polymers
1) cell migration
2) cell shape changes
Microtubules
tubulin polymers
movements inside cell
mitotic spindle
Intermediate filaments
polymers of proteins like lamins for example
8.6 planes of cleavage
8.4 planes of cleavage

Epithelial to mesenchymal transition =
The cell switches from being part of a sheet of cells (epithelium)
to being just a kind of loose cell
Mesenchyme =
a very general term referring to mesoderm
cells that are still deciding what to become.
