Dr. Yips group
is interested in neuronal proliferation, migration and axon guidance.
Their current research on the chick and mouse sympathetic system is aimed
at determining: 1) whether the specification of preganglionic neurons
is under genetic or epigenetic control, 2) the pathway and guidance cues
in the migration of preganglionic neurons, and 3) whether the projection
of preganglionic axons toward their target area is guided by chemoattractant
molecules. Neural transplantations, tissue culture, BrdU labeling, lineage
tracers, monoclonal antibody production, immunohistochemistry, in situ
hybridization, anterograde and retrograde neuronal tracings, and light
and electromicro- scopy are used in the pursuit of these problems. Trainees in Dr. Yips laboratory have the opportunity to learn how to combine modern cell and molecular biological techniques and classical techniques in experimental embryology to answer major unresolved questions on neural development.
