Biomaterial topography cell response
WebThe surface topography affects the cell behaviors most directly via cell sensing and adhesion. 80 Numerous studies have focused on adhesion-guided surface modification to improve the cell response from the perspective of immune regulation. 47,70,81 We evaluated the attachment process by F-actin and vinculin staining, revealing the distinct ... WebApr 16, 2024 · We reveal how surface energy directs ligand topography to alternately promote or inhibit cell mechanosensitivity and response to soft amorphous substrates. This understanding likely resolves conflicting mechanistic theories on how MSCs sense and react to soft biomaterial substrates ( 3 , 4 , 13 – 15 ).
