Advancements in tissue engineering and regenerative medicine have highlighted different strategies of designing hydrogels to replicate the intricate structure cartilage extracellular matrix (ECM) for effective regeneration. However, despite efforts meet elevated structural mechanical demands repair, researchers often overlook challenging environmental conditions at damaged sites such as inflammation, hypoxia, limited availability nutrients energy, which are critical supporting The insufficient oxygen, nutrient availability, oxidative stress avascular limit phosphorylation-mediated bioenergetics cells needed energy required anabolic biosynthesis, cell division, migration during repair. Thus, there is a need develop an advanced approach engineer unique hydrogel system that not only provides properties but also integrates therapeutics (like anti-inflammatory, reactive oxygen species (ROS) scavenging) demand) into hydrogel, may offer holistic solution repairing defects under harsh microenvironment. In this study, we engineered innovative new class theraoenergetic by reinforcing Janus nanofiber (JNF) carrying therapeutic (MgO) bioenergetic (polyglutamic acid), PGA) components dual network photo-crosslinkable hydrogel. Reinforcement JNF microfragments photo-crosslinking synthesized gelatin methacryloyl (GelMA) carboxymethyl chitosan (CMCh) enhances hydrogel's 800% withstand load ensures controlled release magnesium, PGA over 30 days. Co-delivery magnesium with helped synergistically reduce intracellular ROS inflammatory markers IL-6 TNF-α, providing supportive environment enhancing mitochondrial metabolism leading active proliferation chondrogenic differentiation stem deposit glycosaminoglycan (GAG)-rich regenerate cartilage. developed represents promising regenerating microenvironment treat osteoarthritis, rising global health burden.

This study demonstrates a new degradable 3D-printed carboxymethyl chitosan (CMC)/zein bone scaffold loaded with different content of cuprorivaite (Cup) nanoparticles which labeled as CMCS/Z/Cup. Only few studies have utilized these components to fabricate three-component porous osteogenic scaffold. The aim this was comprehensively assess the mechanical and biocompatibility nanocomposite synthesized by 3D printing method. For purpose, Cup powder initially through sol-gel process its confirmation proved using techniques such X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission (TEM). Then, three CMC/Z scaffolds were made contents: group A (0 wt.% Cup), B (2.5 Cup) C (5 Cup). well-ordered microporous high porosity pore connectivity, observed morphological analysis SEM. Additionally, size more homogeneous than that groups C. There no significance differences in physicochemical characterization among groups. Mechanical properties showed values compression modulus are significantly increased addition 2.5% into CMCS/zein matrix, from 1.2 9.6 MPa. incorporation CMCS along zein can provide suitable substrate for growth osteoblast cells after implantation, indicated results vitro degradation. cultured MG-63 cells, showing cell viability content, 95%, 105%, 110% pure polymeric scaffold, reinforced 5% Cup, respectively. As result, designed possess ability be used tissue engineering due having characteristics similar natural bone.
