the duration of embryogenesis , the rate of loss of the ability to proliferation ( a result of final differentiation ) by the initial cell cultures , the error accumulation rate in the genetic cell apparatus ( including both the genome itself and its interactions with the chromatin components ) which determines the rate of ageing and the rate of the tumour incidence rise in particular , are all connected via the level of instability of the epigenetic states of cells .
