Cell Cycle
The life cycle of each cell is
regulated via stimulation from hormones or growth factors. Disruption of the
cycle can affect the health of the body. Most human cells divide from 40 to 60
times before they die. The life cycle of a cell includes the following steps:
■■ Interphase: The cell obtains
nutrients to grow andduplicate. This is actually the period from cell for
mation to cell division. This step may be betterunderstood as being a metabolic
or growth phase.
■■ Cell division (mitosis): The
nucleus divides.
■■ Cytoplasmic division
(cytokinesis): The cytoplasmdivides.
■■ Differentiation: The cell becomes specialized.
