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 ...

Morphogens are signaling molecules that are released from particular areas of tissues, creating a concentration gradient that decreases in concentration further away from the source. This has ...

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 as-synthesized quinary full-concentration-gradient cathode g-NCMAB features a Mn-rich Ni-poor surface and radially aligned primary particles, effectively enhancing surface chemical stability, ...

Creating an artificial “cell-on-a chip” that can mimic the function of biological cells is a big goal for synthetic biology. The development of this idea is on-going, and in this piece, three examples ...
