Confocal microscopy image of nuclei, coloured by depth, of Trichoplax sp. H2, one of the four species of placozoan for which the authors of the study created a cell atlas for. [Sebastian R.

A new study sheds new light on the origins of modern brain cells. Researchers find evidence that specialized secretory cells found in placozoans, tiny sea creatures the size of a grain of sand, have ...

Top: Intestinal stem cells lacking Daam1 (left) or Rnf43 (right) form tumor-like organoids. Bottom: Intestines lacking Daam1 do not form ectopic Paneth cells, a type of secretory cells (left), while ...

Stem cells can differentiate to replace dead and damaged cells. But how do stem cells decide which type of cell to become in a given situation? Using intestinal organoids, scientists identified a new ...
