As the gradient decays, the position of this threshold value moves at varying speed along the membrane, depending on the cell shape. Thus, via this hierarchy of protein concentration profiles, the ...

Critical concentration gradient model is helpful in understanding the mechanism of Z-ring formation. The distribution of positive and negative regulators of Z-ring formation in cell is not random but ...

Top PDMS layer with an array of microwells, potentially containing different reagents. Fluid Loading: Illustration of the process where distinct solutions are loaded into the microwells of the top and ...

In classic cartoons, characters drift along wafting scent trails toward freshly baked pies. Similarly, through a process called chemotaxis, bacteria navigate chemical concentration gradients in search ...

Researchers have succeeded for the first time in recording, in action, a light-driven sodium pump from bacterial cells. The findings promise progress in the development of new methods in neurobiology.

Molecular gradients have been established as a key driving force for cellular organization in the formation of early structures during embryonic development. A new live imaging technique has been ...

The transport of ions is essential to maintain electrophysiological balance on either side of the membrane, called osmotic balance, which is needed for signals to be transduced from their chemical ...
