A response surface method approach was employed to observe the curvature of our system response as a result of variable changes, and a BoxBehnken 3-level factorial design was chosen in lieu of a typical 5-level central composite design (CCD), as the more numerous and axial variable levels associated with the CCD are more difficult to carry out with biological systems
A response surface method approach was employed to observe the curvature of our system response as a result of variable changes, and a BoxBehnken 3-level factorial design was chosen in lieu of a typical 5-level central composite design (CCD), as the more numerous and axial variable levels associated with the CCD are more difficult to carry out with biological systems. mesenchymal stem cells (hMSCs). DOE analysis revealed that matrices created with extended culture period, ascorbate-2-phosphate supplementation, and in ambient oxygen tension exhibited significant correlations with enhanced hMSC differentiation. We validated the DOE model results using DMs predicted to have superior (DM1) Trimebutine maleate or smaller (DM2) osteogenic potential for nave hMSCs. Compared to cells on DM2, hMSCs cultured on DM1 expressed 2-fold higher osterix levels and deposited 3-fold more calcium…
