Dorsal Root Ganglion

Introduction

Dorsal Root Ganglion is a cluster of neurone found in the dorsal root of the spinal nerve. The cells found in the ganglion develops from the neural crest migration at about 4 weeks post-conception (pc).

Developmental Process

Neural Crest Migration in Formation of the DRG

Trunk neural crest cells migrate via a ventromedial pathway on the neural tube during the fourth week of development. Depending on where these cells cease their migration will determine the structure into which they develop. The neural crest cells that will divide to form the dorsal root ganglion cease migration once they have reached the area of the perisomitic vessel next to the neural tube. [1]. Progenitor cells act as the beginning catalysts that lead the neural crest cells to differentiate into the neurons and glial cells that will comprise the DRG. Sox10+ progenitors are one of the most common progenitors that plays a role in the differentiation of the neural crest cells first into neurons and then in glia. TrkA, TrkB, and TrkC are the three classes of neurons following the end of the neural crest migration. [2].
