Les ligands de matrice extracellulaire peuvent être modelés sur des hydrogels de polyacrylamide pour permettre la culture des cellules souches embryonnaires humaines dans les colonies confinées sur des substrats conformes. Cette méthode peut être combinée avec la microscopie de force de traction et des essais biochimiques pour examiner l'interaction entre la géométrie de tissu, les forces cell-générées, et la spécification de destin.
