A collective path toward regeneration
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.
