The cell population types constituting multicellular organisms can be roughly classified,
based on their kinetics, into three main groups: a)(Static) decaying: cell populations having
been built up at some stage of development into a 'store', usually having lost even limited
proliferative capacity, and usually slowly decaying in numbers during the life of the organism
(for example, neurons, muscle cells, oocytes, etc.) b) Transit: cells being produced by a
precursor cell population and having a clearly limited, relatively short peri-od of existence in …
