Chondrogenesis-inductive nanofibrous substrate using both biological fluids and mesenchymal stem cells from an autologous source

Abstract

During the last decade, many cartilage tissue engineering strategies have been developed, being the stem cell-based approach one of the most promising. Transforming Growth Factor-β3 (TGF-β3) and Insulin-like Growth Factor-I (IGF-I) are key proteins involved in the regulation of chondrogenic differentiation. Therefore, these two growth factors (GFs) were immobilized at the surface of a single electrospun nanofibrous mesh (NFM) aiming to differentiate human Bone Marrow-derived Mesenchymal Stem Cells (hBM-MSCs). The immobilization of defined antibodies (i.e. anti-TGF-β3 and anti-IGF-I) allows the selective retrieval of the abovementioned GFs from human platelet lysates (PL). Biochemical assays, involving hBM-MSCs cultured on biofunctional nanofibrous substrates under basal culture medium during 28 days, confirm the biological activity of bound TGF-β3 and IGF-I. Specifically, the typical spherical morphology of chondrocytes and the immunolocalization of collagen type II confirmed the formation of a cartilaginous ECM. Therefore, the proposed biofunctional nanofibrous substrate is able to promote chondrogenesis.
