The ‘immortal hydra’ may help to demystify the process of regeneration by mapping how it regrows its cells.
Self-renewal Fluorescent markers show which genes are activated as stem cells of hydras develop into specific cell types. In one hydra, for example (second from the left), nerve cells glow magenta. A second (second from the right) shows the gene activity in the two stages of development of the animal’s stabbing cells (early green, late red).
