Abstract

How do cells collectively control an organ's behavior? By plucking various numbers of hairs from the mouse skin, Chen et al. show that hairs regenerate only when a sufficiently high density of them are plucked. Remarkably, a hair follicle can only regenerate in concert with other follicles, but not autonomously.
