previous work has demonstrated that these specific interactions between particle and phagocyte are required not only for the initiation of phagocytosis -- that is , attachment of the particle to the phagocytic cells and generation of a signal to trigger phagocyte pseudopod extension -- but also for the subsequent progression of pseudopods over the entire surface of the particle .
