Patent ID: 7662615

Claim:
A system for cultivating cells, comprising: a bioreactor, wherein the cells are disposed within said bioreactor, further comprising a plurality of scaffolds disposed within said bioreactor, and the cells are located in said plurality of scaffolds, wherein said plurality of scaffolds are disc-shaped and said plurality of scaffolds are staked up coaxially; a pump connected to said bioreactor, wherein said pump is used to drive gas into said bioreactor; a coil for generating an induced electromagnetic field applied on the cells within said bioreactor; and an electromagnetic stimulator connected to said coil, wherein said electromagnetic stimulator is used to provide a plurality of first signals and produce said induced electromagnetic field by said coil, whereby said induced electromagnetic field is applied on the cells within said bioreactor, wherein the direction of the magnetic field of said induced electromagnetic field is perpendicular to said plurality of scaffolds.
