NS development in the embryo

Researchers discover signaling molecule that helps neurons find their way in the developing brain

This image shows a section of the spinal cord of a mouse embryo. Neurons appear green, and those that express the Robo3 receptor are labeled red. Commissural axons appear as long, u-shaped threads, and the bottom, yellow segment of the structure represents the midline. (credit: Laboratory of Brain Development and Repair at The Rockefeller University) Rockefeller University researchers have discovered a molecule secreted by cells in the spinal cord that helps guide axons (neuron extensions) during a critical stage of central nervous system development in the embryo. The finding helps solve the mystery: how do the billions of neurons in the embryo nimbly reposition themselves within the brain and spinal … more…
