V2a Interneurons (IMAGE) Drexel University Caption Scientists at Drexel College of Medicine and the University of Texas differentiated embryonic stem cells into V2a interneurons and combined them with neural progenitor cells from a rodent spinal cord. In green, neural progenitor cells that become neurons and glia; in purple, V2a interneurons that are maturing into neurons; in cyan, transplanted neurons that come from the neural progenitor cells.
