Celtaxsys - Biology in Reverse

Figure 1: Chemotaxis and cell polarization in attractive mode for the soil amoeboid Dityostelium discoidium (left) and a human neutrophil (right). As might be apparent from the similarities in cell morphology, the pathways governing cell polarization and induction of chemoattractive chemotaxis are related in the soil amoeba and a migratory human leukocyte. Below each micrograph is an illustration of the major pathways governing cell polarization in response to a chemokine stimulus. Image courtesy of Carole A.
