Tissue homeostasis and non-homeostasis: from cell life cycles to organ states

LE O'Brien - Annual review of cell and developmental biology, 2022‏ - annualreviews.org
Although tissue homeostasis—the steady state—implies stability, our organs are in a state of
continual, large-scale cellular flux. This flux underpins an organ's ability to homeostatically …

The antagonistic relationship between apoptosis and polyploidy in development and cancer
