The model is based on the earlier discovery that the cell-cycle regulator Cdk1 is asymmetrically distributed in the oocyte cytoplasm, where it forms a concentration gradient that extends from the ...

Movement of cells taking place during embryonic development, in patho-physiological conditions or in diseased states (e.g., as a primary mode to generate ...

Chemokines were formerly known as cytokines, and there are several different families ... of about 90 micrometers the cells followed the concentration gradient and located the lymphatic vessel ...

A key feature is their ability to mix different solutions on the chip to easily form step-by-step concentration gradients—ideal for testing how cells respond to varying drug doses, for example ...

Pure water has the highest water concentration. A concentration gradient exists when there is a region of high concentration leading to a region of low concentration: ...

Diffusion Substances move from a high to a low concentration ... against a concentration gradient Mineral ions into plant roots, glucose from the gut into intestinal cells, from where it moves ...

As Frey and colleagues report a new study that appears in the journal Nature Physics, a concentration gradient formed within the cell itself encodes the shape information of the cell and gets ...
