Dr. Kathy Svoboda has been interested in the role of the cytoskeleton in cell shape changes throughout her career. She studied neuroepithelial cell shape changes during optic vesicle formation for her Ph.D. thesis topic, and then started investigating the corneal epithelial response to extracellular matrix as a postdoctoral project.
She is presently working on several projects with the long-term objective of understanding cell-matrix communication in whole tissue development models. Her group has established that just as cultured cells form focal adhesions in response to extracellular matrix proteins, whole tissues also have similar structures termed "cell-matrix attachment complexes" (CMAX). Both the focal adhesion and CMAX contain cell adhesion molecules, actin-associated proteins and signaling molecules. Her lab has shown that these proteins and activated signaling pathways are necessary for reorganizing actin in the embryonic corneal epithelial model. They have also shown that cell-matrix interactions in whole cartilage are necessary for survival and differentiation.
Understanding these relationships will help elucidate the events and interactions that are involved in tissue-specific differentiation and matrix synthesis. Her group has developed experimental approaches to examine the spatial relationships between specific cellular components in whole tissues. These cellular models have been used to determine the three-dimensional relationships between organelles, cytoskeletal proteins and specific mRNA.
In 1998, Dr. Svoboda joined the faculty at Texas A&M University Baylor College of Dentistry. Although she is still pursuing the long-term goals of her research, she has become involved in many other projects in the last 14 years. The new projects (signal transduction pathways controlling palate development, condylar cartilage differentiation and gingival tissue response to nicotine) are related to craniofacial development or cell-matrix interactions in oral tissues.
Dr. Svoboda has served on the executive board and been the program co-chair for the American Association of Anatomists and served as the AAA president from 2005-2007 (www.anatomy.org). She also serves on the editorial board of Developmental Dynamics, Anatomical Record and the European Journal of Dentistry.
The image to the right was the cover for a special issue of CTO on Epithelial-Mesenchymal Transitions. Dr. Svoboda's student, Julia Chang, demonstrated that E-cadherin had an altered distribution in oral cancer cells.
