Cell biology: The not-so-odd couple
Sarah E. Millar1
Abstract
Actively dividing cells do so at a risk — with each division, chromosome ends tend to shorten. Pairing proteins that promote cell division with a chromosome-end repair factor is a smart way to solve this problem.
Embryonic development and homeostasis of adult tissues are regulated by a relatively small number of signalling pathways with astoundingly diverse functions. These include controlling the rate of cell division, regulating the differentiation of cells into organs with complex structures, and activating adult stem cells.
