In contrast, VSMC in sections of non-injured control vessels stained negatively for apoptotic markers, consistent with the low level of cell turnover in healthy vessels [ 6].
L2/3 pyramidal neurons in the mature cortex undergo a low level of synapse turnover (Holtmaat et al. 2005; De Paola et al. 2006), which is increased by altering sensory experience (Holtmaat and Svoboda 2009) and may contribute to memory formation (Cheetham et al. 2008; Hofer et al. 2009; Xu et al. 2009; Yang et al. 2009).

Our results demonstrate that Lmna−/− mice are severely osteopenic and show low levels of bone turnover associated with a decrease in bone formation that exceeds the decrease in bone resorption, clearly mimicking the cellular changes of senile osteoporosis.
Although very low levels of cell turnover are detected in normal adult arteries [ 6], apoptosis and proliferation of VSMC are important, ongoing processes in vascular remodelling [ 7– 9].
High and low levels of population turnover are not restricted, however, to stable populations, as areas that experience high levels of net population change may also experience lower than average levels of population turnover.
