We applied single-cell analysis to the mouse cortex and hippocampus - to our knowledge the most complex tissues analyzed in this way by single-cell methods. We describe 47 distinct subclasses of cells, and find that transcription factors form a complex, layered regulatory code.

This work was a very rewarding collaboration primarily with the Jens Hjerling-Leffler group, as well as a large team of collaborators. I think it proves, once and for all, that single-cell gene expression analysis will revolutionize developmental biology. With single-cell analysis, we have an objective way of observing and classifying all the cells that exist in any tissue, at any time.
