Summary for biologists:  Convergent-extension (CE) is a key process during morphogenesis, but based on classical active matter physics results, it should be unstable. We show that this process can be stabilized by signaling gradients, and we find that CE is only stable when the gradient is parallel to the axis of extension, and unstable when it's parallel to the axis of contraction. Indeed, only the former case seems to appear in nature.
