摘要： A biomimetic lamellar tissue scaffold for tissue regeneration comprises a plurality of lamellae formed of a polymer film and each having a first surface and a second surface. A patterned array of polymer nanofibers protrudes from the first surface of each lamella of the plurality. The lamellae form a plurality of interlamellar spaces between the first and second surfaces of adjacent lamellae. Protuberances formed on the first surface of each lamella maintain the interlamellar spaces. The arrays of polymer nanofibers on the first lamellar surface of each lamella protrude into the interlamellar spaces between adjacent lamellae and are configured to influence the propagation and differentiation of cells populated to or recruited to the scaffold.
