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

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.
