Despite this simplified organization, the destiny of the cells is governed through the three fundamental mechanisms, i.e. proliferation, differentiation and programmed cell death (PCD), which are landmarks of metazoan homeostasis. cell differentiation cell motility regeneration...

..., acclimation did not alter the effect of experimental temperature on cellular speed. These findings suggest that more than one temperature-sensitive mechanism may govern cell motility: the rate-limiting process(es) responsible for speed is distinct from the mechanism(s) underlying directionality...
