Brain Stem Cell Division and Maintenance Studied Using Multi‐isotope Imaging Mass Spectrometry (MIMS)

New neurons are continuously produced from neural stem cells in specific regions of the adult brain of animals and humans. In the hippocampus, a region crucial for cognitive function, neurogenesis responds to a multitude of extrinsic stimuli; emerging evidence indicates that it may be important for behavior, pathophysiology, brain repair, and response to drugs. We have developed an approach to identify and quantify the cellular targets of pro‐ and anti‐neurogenic stimuli, based on reporter transgenic mouse lines in which neural stem and progenitor cells or their progeny are marked by fluorescent proteins. Here, we demonstrate the feasibility of using multi‐isotope imaging mass spectrometry for studying adult neurogenesis. Copyright © 2014 John Wiley & Sons, Ltd.
