Mesenchymal stem cells (MSCs) can generate chondrocytes in vitro, but typically need to be cultured as aggregates in the presence of transforming growth factor beta (TGF-β), which makes scale-up difficult. Here we investigated if polyacrylate substrates modelled on the functional group composition and distribution of the Arg-Gly-Asp (RGD) integrin-binding site could induce MSCs to undergo chond...

Undifferentiated mesenchymal stem cells (MSCs) represent an important source for cell-based tissue regeneration techniques that require differentiation towards specific lineages, including chondrocytes. Chondrogenesis, the process by which committed mesenchymal cells differentiate into chondrocytes, is controlled by complex but not yet completely understood mechanisms that involve many componen...

Degenerative disease and damage to articular cartilage represents a growing concern in the aging population. New strategies for engineering cartilage have employed mesenchymal stem cells (MSCs) as a cell source. However, recent work has suggested that chondrocytes (CHs) produce extracellular matrix (ECM) with superior mechanical properties than MSCs do. Because MSC-biomaterial interactions are ...

Abstract Background Cartilage regeneration is a key step in functional reconstruction for temporomandibular joint osteoarthritis (TMJ-OA) but difficult issue to address. Strontium ranelate (SrR) an antiosteoporosis drug that has been proven affect OA recent years, its effect on chondrogenesis and the underlying mechanism are still unclear. Methods Bone mesenchymal stem cells (BMSCs) from Spragu...

Options for the treatment of cartilage defects include chondral resurfacing with abrasion, debridement, autologous chondrocyte transplantation (ACT), matrix-induced chondrocyte transplantation (MACI), or osteochondral autologous transplantation (OATS). This article describes the new method of autologous matrix-induced chondrogenesis (AMIC), a 1-step procedure combining subchondral microfracture...
