With this in mind, collagen (from bovine skin and tendon) sponges were fabricated with different crosslinking densities, and their physicochemical and biological properties were assessed. As the crosslinking density was increased, the resistance to collagenase digestion, denaturation temperature, compressive stress, and compressive modulus was significantly increased and the free amine content, % swelling, and human dermal fibroblast cytocompatibility were significantly reduced. The tendon-collagen-derived scaffolds exhibited significantly higher compressive stress and compressive modulus values and induced significantly higher human tenocyte DNA concentration and metabolic activity than the skin-collagen-derived scaffolds. In human tenocyte cultures on day 14, the 1 mM 4-arm polyethylene-glycol succinimidyl glutarate tendon-collagen-derived collagen sponges induced significantly higher collagen type III synthesis (as expected at early stages of physiological tendon healing) and downregulated actin alpha 2 (associated with myofibroblast differentiation) and the skin-collagen-derived collagen sponges induced significantly higher collagen type IV synthesis (found primarily at the dermal-epidermal junction) and upregulated prolyl 4-hydroxylase subunit alpha-1 (associated with collagen biosynthesis and constitutes a target for antifibrotic compounds).

Without the degradation in gastrointestinal tract and first-pass metabolism, the intraoral drug delivery system turns out to be an attractive option for macromolecule absorption, which will provide a promising platform for the successful delivery of protein, peptide, nucleic acid, and polysaccharide. Nevertheless, limited bioavailability, short retention time, and poor reproducibility pose a major hurdle to the further application of conventional intraoral drug delivery systems. Recent advances in chemical, material, and engineering techniques bring great opportunities to improve intraoral system fabrication and applications, owing to the high biocompatibility and functional diversity. In this review, we systematically summarize the recent development of smart intraoral drug delivery systems, including fast dissolving oral films, medicinal chewing gum systems, intraoral mucoadhesive systems, physical assisted systems, intelligent intraoral device, and chemically assisted systems. Moreover, the challenges and prospects for clinical and industrial applications of current strategies are well discussed.

More importantly, smart-responsive hydrogels can achieve relevant changes in material morphology or properties under the conditions of changes in physical, chemical, and biological factors, thereby achieving controlled functional molecules release. It is more urgent to design and build smart-responsive hydrogels to achieve precise tissue repair with the introduction of the concept of precision medicine and drug delivery.

This autologous antigen repertoire presents cancer cell membrane-derived nanoparticles highly immunogenic to the body's immune system. Cancer cell membrane-derived nanoparticles antigenically recapitulate the parental cancer cells and can be exploited to induce immune response reactive with tumor-associated antigens (TAAs). The use of the cancer cell membrane-derived nanoparticles to deliver immunostimulatory adjuvants facilitates the cross-presentation of tumor antigens by antigen-presenting cells and their costimulation, triggering potent antigen-specific T responses to eliminate established tumors. These nanoparticles can be engineered to carry immunostimulatory signals to facilitate the cross-presentation of TAAs and the induction of potent antitumor immunity. In this study, cancer cell membrane-based vesicles (CCMVs) are prepared from B16 melanoma cells and engineered to deliver the immunological agent polyinosinic:polycytidylic acid (poly-IC). We show that CCMV is preferentially uptaken by bone marrow-derived dendritic cells (BMDCs) as compared to other cell types (macrophages, fibroblasts). The efficient delivery of poly-IC to BMDCs results in enhanced antigen cross-presenting capability of BMDCs and T-cell activation.
