Unlike humans, zebrafish can completely regenerate their hearts after injury. They owe this ability to the interaction between their nervous and immune systems, as researchers now report.

If cells in cell cultures grow while being treated with division-suppressing agents, their growth becomes excessive and they permanently lose their ability to divide. However, if the cells are treated with a combination of division inhibitors and growth inhibitors, they remain capable of dividing after these substances have been discontinued. The findings could be transferred to certain cancer therapies, but first need to be clinically tested and confirmed.
