Cell Migration

Research Synopsis

The Cramer lab studies actin-based mechanisms of cell polarity and cell migration. Cell migration is essential for life; required throughout embryo development, and for tissue repair and immunity in both the embryo and the adult. It also contributes to several important diseases, including inflammatory diseases, mental retardation and the spread of cancer. Determining molecular mechanisms controlling cell migration thus promises to provide effective therapeutic strategies for treating disease. We are interested in how migrating cells reach new territory and how they polarize to activate motility. We focus on determining actin cytoskeleton-based mechanical forces that drive these processes analysed at high spatiotemporal resolution, mainly using primary fibroblasts and dictyostelium as model systems.
