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.

Ch. 10: Cell Differentiation, Stem Cells

10.1 differentiation

10.23 neural crest derivatives

Fig Fate Specify Determined (committed) Differentiate = the cell becomes the final cell type differentiation is irreversible

Fig “master regulators” like MyoD are transcription factors that can cause cells to become determined when the gene is expressed.
