Figure 4From: Multiscale computational analysis of Xenopus laevis morphogenesis reveals key insights of systems-level behaviorCalculating cell force vectors from fibronectin gradients. (A) Fn concentration across a single cell. As cells move forward, a gradient of fibronectin is established from the leading edge to the trailing edge. (B) A Fn gradient is also established across the entire explant length.Back to article page
