Cell death is part of the lifecycle of every multicellular organism. Nineteenth-century pathologists already recognised that organised forms of cell death must exist to explain the demise and turnover of cells during metamorphosis (of insects), embryogenesis and normal tissue homoeostasis [ 1 ]. Nevertheless, Kerr, Wyllie and Currie in their seminal paper of 1972, were the first to collate and define the distinct morphological features of controlled cell death in different contexts [ 2 ]. To describe the processes of cell deletion observed under both physiological and pathological conditions, they coined the term ‘Apoptosis’ (derived from the Greek word ‘ἀπόπτωσις’, meaning ‘dropping off or falling off’ of petals from flowers). Kerr, Wyllie and Currie defined apoptosis as a mechanism ‘ complementary to mitosis in the regulation of animal cell populations’ . In addition, they already recognised the potential to use this programmed form of cell death for cancer therapy, but they also emphasised the occurrence of apoptosis during cancer development. In this article, some 50 years after its initial publication in The British Journal of Cancer , we revaluate and put the authors initial assumptions and general concepts about apoptosis into the context of modern-day biology
