Biophysicists at Ludwig-Maximilians-Universitaet (LMU) in Munch have developed a new theory, which accounts for the observation that cells can perceive their own shapes, and use this information to ...

In a ground-breaking study, researchers report a new technique that allows them to visualize the distribution of retinoic acid in a live zebrafish embryo, in real-time. This technique enabled them to ...

Morphogens are secreted signalling molecules that organize a field of surrounding cells into patterns. They form a gradient of concentration emanating from a localized source, and determine the ...

A new article provides new insights into how immune cells find their way through tissues. The findings provide the first evidence for directed cell migration along concentration gradients of chemical ...

Scientists designed autonomous nanovesicles capable of following glucose concentration gradients, even through the blood brain barrier in rats. From flies landing on food to the retraction of the ...

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 ...
