Articular cartilage injury is characterized by limited self-repair capacity due to the shortage of blood vessels, lymphatics, and nerves. Hence, this study aims to exploit a classic injectable hydrogel platform that can restore the cartilage defects with minimally invasive surgery, which is similar to the natural extracellular microenvironment, and highly porous network for cell adhesion and proliferation. In this study, an injectable scaffold system comprised of silk fibroin (SF) and hyaluronic acid (HA) was developed to adapt the above requirements. Besides, methylprednisolone (MP) was encapsulated by SF/HA scaffold for alleviating inflammation. The SF/HA hydrogel scaffold was prepared by chemical cross-linking between the lysine residues of SF via Schiff base formation, and pore diameter of the obtained hydrogels was 100.47 ± 32.09 µm. The highly porous nature of hydrogel could further benefit the soft tissue regeneration. Compared with HA-free hydrogels, SF/HA hydrogel showed more controlled release on MP. In ovo experiment of chick embryo chorioallantoic membrane (CAM) demonstrated that SF/HA hydrogels not altered the angiogenesis and formation of blood vessels, thus making it suitable for cartilage regeneration. Furthermore, in vivo gel formation was validated in mice model, suggesting in situ gel formation of SF/HA hydrogels. More importantly, SF/HA hydrogels exhibited the controlled biodegradation. Overall, SF/HA hydrogels provide further insights to the preparation of effective scaffold for tissue regeneration and pave the way to improve the articular cartilage injury treatment.
