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.

摘要

在皮肤中，交感神经、立毛肌和毛囊形成一个三联体单元，引起毛发竖起或鸡皮疙瘩。在本期《细胞》杂志上，Schwartz 等人报道，除了鸡皮疙瘩之外，肌肉锚定神经还与毛囊干细胞形成“突触样”连接，以促进毛发在寒冷时的再生。
