No example of binding of magnetic particles to mesenchymal cell, chondrocyte and other cells whose use in regenerative medicine, etc. can be expected is known. Thus, whether or not cells having magnetic particles bound thereto after administration are retained in local by outside magnetism and whether or not the cells can exhibit the intrinsic activity are studied. In particular, there are provided magnetic cells comprising mesenchymal cells or chondral cultured cells having magnetic particles bound to the surface thereof, which magnetic cells are administered into a body. The magnetic cells can be retained in a seat of disease for a prolonged period of time by applying magnetic field from outside. Further, a drug delivery system can be constructed by causing the magnetic cells to contain drugs. |
