A novel use of centrifugal force for cell seeding into porous scaffolds

W T GodbeyAnthony Atala


A novel rotor was constructed to allow for the seeding of porous scaffolds via centrifugal force. Using cell seeding times of 10 min, this method placed significantly (roughly 3-fold) more cells into poly(glycolic acid) scaffolds than 24 h of spinner flask seeding or static seeding. There were no significant differences in the mitochondrial activity per cell between the 3 seeding methods. Cell distribution was noted to be homogeneous throughout the scaffold thickness for the centrifugation method, as opposed to surface seeding for the spinner flask method. Centrifugation was especially efficient at low cell concentrations (1.33 x 10(5) cells/ml). This system is useful for the seeding of biomaterials having cylindrical or planar geometries, and may be used under conditions that require low cell numbers and/or short seeding time periods.
