Erratumin: Cell. 2011 Dec 23;147(7):1640.Abstract Programmed Cell Death (PCD) plays a fundamental role in animal development and tissue homeostasis. We focus on the function and regulation of apoptotic proteins, including caspases, the key executioners of apoptosis, highlighting the functions of these proteins in cell differentiation and tissue remodeling. Finally, we explore the connections between apoptosis, stem cells and cancer, focusing on how apoptotic cells release a variety of signals to communicate with their cellular environment, including factors that promote cell division, tissue regeneration, and wound healing.

Proc Natl Acad Sci U S A.2015 Jun 30;112(26):E3365-73.Abstract In this study, we report a previously unidentified strategy of self-repair, where moon jellyfish respond to injuries by reorganizing existing parts, and rebuilding essential body symmetry, without regenerating what is lost. we find that forces generated by the muscular network are essential for symmetrization. Furthermore, decreasing pulse frequency using muscle relaxants slowed symmetrization, whereas increasing pulse frequency by lowering the magnesium concentration in seawater accelerated symmetrization. Self-repair in Aurelia proceeds through the reorganization of existing parts, and is driven by forces generated by its own propulsion machinery.
