Biological Barriers, Genetics, Neurobiology, Regenerative MedicineProjects in our laboratory are focused on developmental neurobiology:
1. Development and aging of the adult stem cells and their ependymal niche in the forebrain. We use mouse genetics in combination with molecular, biochemical, and cell biological approaches to address fundamental questions regarding the functional significance of ependymal cells during development and aging.
2. Role of cell cycle regulators in symmetric and asymmetric divisions of neural stem cells in the developing and postnatal brain. We use mouse genetics, biochemical assays, and state-of-the-art imaging tools to understand mechanisms that regulate the decision of neural stem cells to divide symmetrically or asymmetrical in the embryonic and postnatal stem cell niches.

Researchers Find Lack of Protein Sp2 Disrupts Neuron Creation in BrainA protein known as Sp2 is key to the proper creation of neurons from stem cells, according to researchers at North Carolina State University. Understanding how this protein works could enable scientists to “program” stem cells for regeneration, which has implications for neural therapies.

CVM Neurobiologist Maps Areas of the Brain Associated with Affective Aggression in Mice
A North Carolina State University College of Veterinary Medicine researcher has created a roadmap to areas of the brain associated with affective aggression in mice. This roadmap may be the first step toward finding therapies for humans suffering from affective aggression disorders that lead to impulsive violent acts. Affective aggression differs from defensive aggression or
