Mitotic phase - MPF triggers mitosis, characterized by several stages, know descriptions of each stage Prophase Prometaphase Metaphase Anaphase Telophase 3. The Control of Cell Division Cell Division is regulated by many factors. Every type of cell has certain essential nutrient requirements that if unmet will prevent cell proliferation. Cytologist study cell behavior by using selected drugs that effect cytoskeletal structures. Among these drugs are Colchicine or Colchimid that depolymerizes microtubules and blocks mitosis, Cytoclasin B, D or E etc which inhibit addition of actin monomers thus preventing cytokinesis, Vinblastin or vincristine, or taxol which stabilize microtubules thus preventing mitosis.
Poisons can control cell division.
Many types of animal cells grow only when in the presence of a particular protein or growth regulator. PDGF is one example that promotes fibroblasts. FGF-1 is another that promotes development of endothelial cells, or TCGF which is a T cell growth factor. Growth factors are important in regulating many types of cell division. When cells get to touching each other they stop growing.
