The objective of this study was to determine the effects of hydrostatic pressure (HP) on the biochemical properties and gene expression of mesenchymal stem cells (MSCs) on scaffolds for cartilage tissue engineering composed of poly(caprolactone) (PCL) poly(vinyl alcohol) (PVA) gelatin (GEL) semi interpenetrating polymer network (semi-IPN). The MSCs were(More)
Using a numerical method based on sub-super solution, we will obtain positive solution to the coupled-system of boundary value problems of the form −∆u = λ 1 f (v) + µ 1 h(u) in Ω −∆v = λ 2 g(u) + µ 2 γ(v) in Ω u = 0 = v on ∂Ω where −∆ is the Laplacian operator λ 1 , λ 2 , µ 1 , µ 2 are nonnegative parameters, and Ω is a bounded region in R n , with smooth(More)
