Abstract
Disclosed is a method of growing cells on biodegradable microcarrier particles and more specifically growing chondrocytes for an extended period of time until they aggregate. These aggregated cells can be injected directly or shaped for implantation into the body. In another embodiment of this invention, the cell microcarrier aggregates are grown in a mold that is shaped to conform to the geometry of the desired body part to be replaced. An apparatus for shaping the aggregated cells is disclosed. The aggregated cells can be supplied in a kit.
