title: Differentiation of human bone marrow mesenchymal stem cells on decellularized extracellular matrix materials.
abstract: Mesenchymal bone marrow stromal cells may be a source of cells to preseed decellularized biologic mesh materials for improved cellularization and promote a more physiologic tissue after remodeling. Spontaneous differentiation of mesenchymal stromal cells on the decellularized material would be undesirable. Conversely, induced differentiation of mesenchymal stem cells (MSC) on the material would suggest that these materials may have promise as scaffold materials for bone, cartilage, or adipocyte formation. Two sources of mesenchymal cells were evaluated for induced differentiation in control wells. These MSCs were also evaluated for spontaneous or induced differentiation on decellularized porcine dermis and mesothelium materials. Primarily harvested bone marrow MSCs and commercially obtained MSCs were induced into osteoblasts and adipocytes on decellularized dermis and mesothelium materials. The MSCs were able to be induced into chondrocytes in pellet form but not when grown as a monolayer on the materials. The MSCs did not undergo spontaneous differentiation when grown on the materials for up to four weeks. MSC grown on decellularized porcine dermis or mesothelium do not spontaneously differentiate and may serve as a source of autologous cells for preseeding these extracellular matrix materials prior to implantation.
