Gradients of molecular signaling factors play an essential role in numerous events in embryonic development, from patterning limb and organ formation to the intricate shaping of the brain and ...

Quantum dots diffuse within living cells in a nearly two-dimensional fashion. This result, which was obtained using a new 3D microscopy technique that can track single particles, sheds fresh light on ...

New work describes vital aspects of diffusion processes in tissue development, including the roles that molecular diffusion gradients have on stem cell signaling pathways along with new modeling tools ...
