Where this comes from

Abstract

In the skin, sympathetic nerves, arrector pili muscles, and hair follicles form a tri-lineage unit to cause piloerection or goosebumps. In this issue of Cell, Schwartz et al. report that, beyond goosebumps, muscle-anchored nerves form "synapse-like" connections with hair follicle stem cells to promote hair regeneration in response to cold.
