Gene therapy, which treats genetic diseases by fixing defective genes, has gained significant attention. Viral vectors show great potential for gene delivery but face limitations like poor targeting, uncontrolled release, and risks from high-dose can lower efficiency trigger immune responses. Loading viral onto tissue engineered scaffolds presents a promising strategy to address these challenges, their widespread application remains limited due concerns regarding vector bioactivity, scaffold biocompatibility, the stability of sustained release. An adeno-associated virus (AAV), recognized its safety, high efficiency, low immunogenicity, was employed as model virus. In this study, we developed an electrospun (AAV/PCL-PEO@Co-ES) encapsulating AAV within core–shell fibers composed polycaprolactone (PCL) polyethylene oxide (PEO) via coaxial electrospinning. This configuration ensures protection while enabling controlled The physicochemical characterization results indicated that exhibited excellent mechanical properties (tensile strength: 3.22 ± 0.48 MPa) wettability (WCA: 67.90 8.45°). vitro release cell transduction assays demonstrated AAV-loaded effectively controls transduction. Furthermore, both in vivo evaluations good biocompatibility efficient delivery. These findings highlight AAV/PCL-PEO@Co-ES safe effective platform delivery, offering valuable insights future design clinically relevant systems.

Tension-free hernioplasty has effectively reduced postoperative recurrence and mitigated complications by employing polymer patches. However, clinically used patches often fall short in terms of the anti-deformation, anti-adhesion, tissue integration functions, which can result visceral adhesions foreign body reactions after implantation. In this study, a Janus three-layer composite patch was developed for abdominal wall defect repair using combination 3D printing, electrospraying, electrospinning technologies. On side, dense electrospun polyvinyl alcohol/sodium hyaluronate (PVA/HA) scaffold fabricated to inhibit cell adhesion. The middle layer, composed polycaprolactone (PCL), provided mechanical support. muscle-facing loose porous nanofiber created through electrospraying electrospinning, promoting adhesion migration facilitate regeneration. Mechanical testing demonstrated that possessed excellent tensile strength (23.58 N/cm), surpassing clinical standard (16 N/cm). Both vitro vivo evaluations confirmed patch's outstanding biocompatibility. Compared with control PCL patch, significantly enhanced animal models. Collectively, integrated tissue-regenerative properties, providing promising solution effective repair.
