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 ...

Cell migration is stimulated and directed by the interaction of cells with extracellular matrix, neighboring cells or chemoattractants and is key to processes such as development and metastasis.

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 ...

Number of tumor-infiltrating lymphocytes in breast cancer brain metastases compared to matched breast primaries. This is an ASCO Meeting Abstract from the 2017 ASCO Annual Meeting I. This abstract ...

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 ...

This video explains how particles spread through diffusion from areas of high concentration to low concentration. Different factors affect the rate of diffusion – temperature, concentration gradient ...
