Abstract
Provided is a magnetically actuated microscaffold for minimal invasive osteochondral regeneration. More particularly, provided is a composition for cartilage regeneration, a microscaffold for cartilage regeneration, in which magnetic particles and cartilage regeneration cells are loaded on the surface of or within a 3-dimensional porous microstructure composed of a biodegradable polymer and having a diameter of 200-300 μm; and a microscaffold for bone regeneration, in which magnetic particles and bone regeneration cells are loaded on the surface of or within a 3-dimensional porous microstructure composed of a biodegradable polymer and having a diameter of 700-900 μm.
