Background Mesenchymal stem cells are a promising cell source for chondrogenic differentiation and have been widely used in several preclinical and clinical studies. However, they are prone to an unwanted differentiation process towards hypertrophy that limits their therapeutic efficacy. Matrix metallopeptidase 13 (MMP-13) is a well-known factor regulated during this undesirable event. MMP-13 is a collagen degrading enzyme, which is also highly expressed in the hypertrophic zone of the growth plate and in OA cartilage. Accordingly, we investigated the effect of MMP-13 inhibition on MSC hypertrophy. Methods In this study, 5-bromoindole-2-carboxylic acid (BICA) was used as an inhibitory agent for MMP-13 expression. After identifying its optimal concentration, BICA was mixed into a hydrogel and the release rate was studied. To prepare the ideal hydrogel, chondroitin sulfate (CS) and platelet lysate (PL) were mixed with sodium alginate (Alg) at concentrations selected based on synergistic mechanical and rheometric properties. Then, four hydrogels were prepared by combining alginate (1.5%w/v) and/or CS (1%w/v) and/or PL (20%v/v). The chondrogenic potential and progression to hypertrophy of human bone marrow-derived mesenchymal stem cell (hBM-MSC)-loaded hydrogels were investigated under free swelling and mechanical loading conditions, in the presence and absence of BICA. Results Viability of hBM-MSCs seeded in the four hydrogels was similar. qRT-PCR revealed that BICA could successfully inhibit MMP-13 expression, which led to an inhibition of Coll X and induction of Coll-II, in both free swelling and loading conditions. The GAG deposition was higher in the group combining BICA and mechanical stimulation. Conclusions It is concluded that BICA inhibition of MMP-13 reduces MSC hypertrophy during chondrogenesis.

“…Semipermanent junction points would be formed by the interanchored long chains with enough strength in the polymer network, and the formed networks give an enhancement of the contact and preservation of water molecules . The mount of hydrophilic groups of the polysaccharide varies from a fraction to several thousand times of their own weight when swelled with water . Some functional sections can stabilize the 3D frameworks that allow the interchains conglutinating to avoid dissolution of gels.…”

Polysaccharide is an abundant and reproducible natural material that is biocompatible and biodegradable. Polysaccharide and its derivatives also possess distinctive properties such as hydrophilicity, mechanical stability, as well as tunable functionality. Polysaccharide‐based hydrogels can be constructed via the physical and/or chemical crosslinking of polysaccharide derivatives with different functional molecules, as porous network structures or nanofibrillar structures. This review discusses the biomedical applications of polysaccharide‐based hydrogels containing native polysaccharides, polysaccharide derivatives, and polysaccharide‐composite hydrogels. Recent works on the fabrication, physical properties, advanced engineering, biomedical applications of cellulose‐, chitosan‐, alginate‐, and starch‐based hydrogels are also elaborated. Such porous swelling scaffolds exhibit great advantages at the interface of a negative pressure system such as wound dressing. In addition, the authors also discuss and summarize the exemplary research works of these hydrogels in the applications of drug release, wound dressing, and tissue engineering. Finally, challenges and future perspectives about the development of polysaccharide‐based hydrogels are discussed.
