Document Summary
What is developmental biology: how you get from one cell to multiple cells cell undergoes stereotypical divisions. We do not have the answer to this yet: embryonic development, occurs in all animals, cell divisions, fertilizations, reproduction, differentiation, morphogenesis. Can also use markers to determine where things are, etc. Differentiation: from one cell you get two daughter cells, genome is the same in these two daughter cells . This includes specialization: specialization and therefore differentiation, this is largely determined by gene expression not that the genetic information is different, it is simply used differently. Can be undifferentiated in lab now but very chemically involved. The precursors to these cells however may have several different options. Morphogenesis: linked to biological form, different embryos, organs, etc. all look different; this is a result of differential morphogenesis, cell-cell interactions, cell adhesion, cytoskeleton: allows cell to change its form. This is a direct consequence of how the cytoskeleton changes.
