Hydrogels have the characteristics of high water content, adjustable size, and good biocompatibility, and their surfaces are suitable for multivalent conjugation. These properties make them ideal for delivery systems for preparing cancer vaccines. Alfa Cytology provides high-quality hydrogel delivery system development services to help our clients with cancer vaccine development.
Hydrogels are widely used in biomedical fields because of their designability and simulation of extracellular matrix. It also plays a variety of roles in the delivery of cancer vaccines. Here are some of the advantages of hydrogel delivery systems.
| Advantages | Description |
| Controllable Release | The controlled release properties of the hydrogel allow in situ precise release of the payload in time and space to further enhance the strength and durability of the immune response to cancer vaccines. |
| Superb Encapsulation | The porous structure can improve the encapsulation efficiency of hydrogels. Except for antigens, it can also be loaded with adjuvants, cytokines, checkpoint inhibitors, etc., to collaboratively enhance the anti-tumor efficacy of cancer vaccines. |
| Multiple Epitope Presentation | As carriers in cancer vaccine delivery systems, hydrogels have received a lot of attention because they can encapsulate various antigens/immunomodulators and protect them from degradation. This allows the hydrogel to simultaneously act as an immunosuppressive and stimulating immune response. |
| Others | Hydrogels also exhibit excellent hydrophilicity, adjustable swelling, and can simulate extracellular matrix. |
Hydrogels, one of the most popular delivery systems, are described as three-dimensional cross-linked networks capable of holding large amounts of water. Notably, the unique properties of hydrogels give them great potential for cancer vaccine delivery. Targeting different customer needs, Alfa Cytology provides diversified hydrogel delivery systems development services, including but not limited to the following.
Injectable Hydrogel Delivery Systems Development Service
The injectable hydrogel formed in the tumor site can be directly injected into the pathological site through a syringe, effectively avoiding invasive implantation operation, easy operation, and better tolerance. In addition, injectable hydrogels are often designed to be responsive carriers, such as temperature-responsive, pH-responsive, or shear force-responsive. It can also be combined with light and magnetic to expand the application range. Therefore, injectable hydrogels could serve as the next generation of cancer vaccine delivery systems due to their unique in situ formation, in situ delivery of therapeutic molecules, non-invasive administration, and potential as immune adjuvants.
Bio-derived Hydrogel Delivery Systems Development Service
Biomimetic materials and technologies play an important role in reshaping the field of cancer nanomedicine. By mimicking the chemical and biological properties ideal in nature, the biomimetic properties of the hydrogel cancer vaccine delivery platform can effectively deliver therapeutic cargo to the tumor site, amplify the biological activity of antigens and adjuvants, and enable spatio-temporal control and on-demand immune activation.
Programmed Hydrogel Delivery Systems Development Service
In situ tumor vaccine (ISV) has been recognized as a promising anti-tumor strategy, however, its therapeutic effectiveness has been limited by multiple barriers. The hydrogel delivery system with programmed properties could be used to cascade and amplify the anti-tumor immune response induced by ISV. Anti-cancer drugs and adjuvants are preferentially released, inducing immunogenic tumor cell death and antigen-presenting cell activation. Subsequently, the decomposed scaffold material transformed the anti-inflammatory M2-like macrophages into the M1 type, reversing the immunosuppressive tumor microenvironment (TME). Continuous breakdown releases large amounts of anti-PD-L1 antibodies, rejuvenating the depleted effector T cells. Eventually, the tumor growth was significantly inhibited.
