An international team led by Xavier Trepat, ICREA Research Professor and Group Leader at IBEC, in collaboration with the IRB, researchers from the UB and UPC universities in Barcelona, and the Curie Institute of Paris, has deciphered the mechanisms leading the crypts to adopt and maintain their concave shape, and how the migration movement of the cells towards the peaks occurs, without the intestine losing its characteristic folded shape.
Using mouse stem cells and bioengineering and mechanobiology techniques, researchers have developed mini-intestines, organoids that resemble the three-dimensional structure of peaks and valleys, recapitulating tissue functions in vivo. Using microscopy technologies developed by the same group, researchers carried out high-resolution experiments for the first time that have allowed them to obtain 3D maps showing the forces exerted by each cell.
