Recent work has related nuclear DNA morphometry to cell function during the cycle of synchronized mammalian cells (1) (see also chapter by Nicolini and Belmont) during the G0–G1 transition of confluent human diploid fibroblasts stimulated to proliferate (2), as well as during virus transformation (3) and aging (4). However, those studies did not yet establish a causal relation. It is still unclear whether a change in the functional state in the cell results in altered nuclear morphology or whether an altered nuclear morphometry results in an altered functional state (and it is a requirement for the initiation of this altered functional state). At the same time cell geometry appears causally correlated with cell proliferation in normal cells but not in transformed cells (5). We have therefore recently explored the nuclear DNA morphometry changes with respect to cell geometry during various functional states to establish the role of their coupling (or uncoupling) in this control of normal and abnormal cell growth.
