Research Abstract

Directional cell migration is orchestrated cellular process that is required for a variety of physiological processes such as embryogenesis, wound healing, angiogenesis, as well as carcinogenesis. Migrating cells show a distinct polarity with forming front-rear axis toward the direction. In this study, focusing on Rho family GTPases that is critical regulator in polarized migration, we aimed to elucidate the molecular mechanisms governing migratory behavior and cell polarity.
