Multicellular aligned bands disrupt global collective cell behavior

Acta Biomaterialia, 2022
AbstractMechanical stress patterns emerging from collective cell behavior have been shown to play critical roles in morphogenesis, tissue repair, and cancer metastasis. In our previous work utilizing microcontact printing to geometrically constrain valvular interstitial cell monolayers into specific shapes, we demonstrated that the general patterns of ...
