Embryonic Progenitors in Spinal Development and Repair

A new STEM CELLS Translational Medicine study from researchers led by Shuying Yang (University of Pennsylvania, Philadelphia, PA, USA) aimed to explore the basic mechanisms of spine development by studying Col2+ progenitor cells. Li et al. discovered that embryonic Col2+ cells contribute primarily to spinal cord development and that Col2+ progenitors participate in intervertebral disc repair and regeneration.
