Messenger functions of cell death during development and homeostasis Available to Purchase

In our human society, would you not want to know if your neighbor suddenly passed away? Tissues and cells are not that different. Cell death is an inevitable part of tissue homeostasis and comes in different flavors that can either be a consequence of an injury or a regulated phenomenon (such as programed cell death). Historically, cell death was viewed as a way to discard cells, without functional consequences. Today, this view has evolved and recognizes an extra layer of complexity: dying cells can provide physical or chemical signals to notify their neighbors. Like any type of communication, signals can only be read if surrounding tissues have evolved to recognize them and functionally adapt. This short review aims to provide a summary of recent work interrogating the messenger functions and consequences of cell death in various model organisms.
