Discovery of how organs form helps researchers to develop future diabetes treatments

A new study reveals that the development of progenitor cells depends on protein quantity and interaction with other cells. Cells with high P120ctn expression remain in the central part of the pancreas, while those with low expression migrate to the peripheral area, where they acquire their final fate.
