A rapidly developing area of interest is cell migration and its regulation. We are pursuing studies of growth factors and other signals in regulating the transition of cells from differentiated, quiescent phenotypes to migratory phenotypes. In particular we are interested in the signals that regulate the acquisition of a polarized migratory phenotype and determine the mode of migration (e.g., coordinated migration by cell ensembles vs. individual cell migration; directed vs. random migration). These studies encompass reorganization of cytoskeleton and other intracellular components, navigation, adhesion, signaling, trafficking, and proliferation. Specific projects focus on the transition of vascular smooth muscle cells from a normally differentiated and quiescent phenotype to a migratory phenotype, such as occurs during normal or pathological angiogenesis.
A second, long-standing area of interest in the lab is anatomical and synaptic architecture in the central nervous system. These studies investigate the exquisite organization and specificity of connections between nerve cells, how this architecture develops and is affected by insult, and its capacity for repair. Most of our previous work has utilized the retina as a model system, but other areas of the central nervous system are also of interest.
Technical approaches employed in the lab integrate anatomical, pharmacological and molecular methods to manipulate and visualize signaling processes, cytoskeletal dynamics and cell behavior. Approaches include shRNA and pharmacological treatments to manipulate expression or activity of specific proteins, expression of fluorescent reporters and biosensors, live cell imaging to directly visualize cellular behaviors, and immunolabeling at the light, confocal, and electron microscopic levels.
