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.

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 ...

This is a preview. Log in through your library . Abstract A Stefan problem is formulated for a diffusion equation where the Fickian flux is supplemented by a stress gradient term. The stress in turn ...

·The supply of hydrogen ions will also depend upon their concentration, i.e. the pH of the electrolyte. A concentration gradient in the electrolyte is illustrated. ·If the electrolyte is unstirred, ...
