The Delayed-Onset Mechanical Pain Behavior Induced by Infant Peripheral Nerve Injury Is Accompanied by Sympathetic Sprouting in the Dorsal Root Ganglion

<div>In L5 DRG of adult rats, TH-IR (green) fibers widely sprout around the CGRP (red)-positive neurons or axons after surgery (a–d). Infant rats show the delayed sprouting TH-IR fibers adjacent to neurons or axons expressing CGRP. Scale bars: 100 <i>μ</i>m.</div>
