One of my special interests at Rensselaer Polytechnic Institute is to introduce students to advanced techniques in cell biology to prepare them for careers in basic and applied research. To that end, one of our advanced courses, Cell & Developmental Biology Laboratory, utilizes several techniques such as cell culture, immunofluorescence microscopy, computer image analysis, SDS-PAGE, affinity chromatography, and Western blot analysis to provide the investigative tools necessary to examine a number of parameters in normal and cancer cells. Our students study the roles of the extracellular glycoprotein fibronectin in the mediation of such events as cell adhesion, cytoskeletal dynamics, and the maintenance of cell shape. In collaboration with Drs. Charles Keese and Ivar Giaever, the students will be using the ECIS system to study some of these phenomena at a level of sophistication heretofore unprecedented in the teaching laboratory.
