An in silico axisymmetric multistage model of linear biphasic mesenchymal stem cell and chondrocyte protein secreted-matrix interactions for the reconstruction of the dynamic mechanical environment of a time varying magnetic field expanded chondrocyte biphasic finite elemental model in articular cartilage for the evaluation of the ability of natural and synthetic scaffolds in providing an appropriate environment for growth and sustain of the chondrogenic capacity of de-differentiated of cartilage-derived L-lactic glycolic acid (PLGA) loaded chondrocytes for and then for autologous transplantations.
