Document Summary
Indiscriminate and continuous - do whatever they want. Can produce two or three daughter cells at mitosis - that"s how you get exponential growth. Cell proliferation begins when stem cell enters cell cycle. Time from entering to division into to 2 identical cells = germination time. Cell comes in, resting phase, dormant, synthesis stage, mitosis when they split, make daughter cell: life cycle of cell, m - mitotic; cell division. G1 - post mitotic; have growth and differentiate (mature); variable length of time. G2 - pre mitotic; 2 hours; genetic and protein synthesis. The more primitive and poorly differentiated and more immature, the poorer prognosis. You have these right now and normally regulate cell process; these notify the body to kill bad cells, they keep cells mature functioning and moving. If mutated, will start to act like an oncogene (tumor-inducing gene)
