| Open AccessMouse embryo geometry drives formation of robust signaling gradients through receptor localization
How receptor localization affects morphogen gradient formation during embryonic development is unclear. Here, the authors study the relationship between the BMP gradient, receptor localization, and compartmentalized geometry in the early mouse embryo, using experimental data and computational simulation.

Sensitivity control through attenuation of signal transfer efficiency by negative regulation of cellular signalling
How the sensitivity of biological and pharmacological signalling responses is controlled is poorly understood. Here, computational analyses and cellular experiments show that the sensitivity of a simple biochemical reaction to activators and inhibitors is controlled by negative regulation of cellular signalling.
