dc.description.abstractThe lack of effective and long-term treatments for articular cartilage defects has increased the interest for innovative tissue engineering strategies. Such approaches, combining cells, biomaterial matrices and external biochemical/physical cues, hold promise for generating fully functional cartilage tissue. Herein, this study aims at exploring the use of the major cartilage glycosaminoglycans (GAGs), chondroitin sulfate (CS) and hyaluronic acid (HA), as external biochemical cues to promote the chondrogenic differentiation of human bone marrow- and synovium-derived mesenchymal stem/stromal cells (hBMSC/hSMSC) on custom-made 3 D porous poly (ε-caprolactone) (PCL) scaffolds. The culture conditions, namely the chondrogenic medium and hypoxic environment (5% O2 tension), were firstly optimized by culturing hBMSCs on PCL scaffolds without GAG supplementation. For both MSC sources, GAG supplemented media, particularly with HA, promoted significantly cartilage-like extracellular matrix (ECM) production (higher sulfated GAG amounts) and chondrogenic gene expression. Remarkably, in contrast to tissues generated using hBMSCs, the hSMSC-based constructs showed decreased expression of hypertrophic marker COL X. Histological, immunohistochemical and transmission electron microscopy (TEM) analysis confirmed the presence of typical articular cartilage ECM components (GAGs, aggrecan, collagen fibers) in all the tissue constructs produced. Overall, our results highlight the potential of integrating GAG supplementation, hSMSCs and customizable 3 D scaffolds toward the fabrication of bioengineered cartilage tissue substitutes with reduced hypertrophy.
