Ignoring matrix boundaries when the LKB1 master kinase is gone

Gradients of soluble attractants as well as extracellular matrix (ECM) proteins serve as cues for directional cell movement. Such "chemotaxis" and "haptotaxis" steers migration of cells during embryonic development, wound healing, and immune responses. In this issue, Chan et al. (2014. J.

In a follow-up field experiment, we find that the per person restroom ...
