Synergistic effect of waste-derived β-tricalcium phosphate microbeads loaded in hydroxyapatite-keratin-polyvinyl alcohol composite matrix in drug release for osteosarcoma treatment
Background
Sustained drug delivery system (DDS) for clinically relevant osteosarcoma medications is a promising strategy for treatment. β-tricalcium phosphate (β-TCP) microbeads loaded with doxorubicin hydrochloride (DOX) and cis-diamminedichloroplatin (CDDP) anticancer drugs in a matrix of hydroxyapatite-keratin-polyvinyl alcohol composite matrix scaffolds (HAp-K-PVA) was developed as promising DDS. HAp, β-TCP, and K utilized for the development of DDS were resourced from avian eggshells and human hairs, respectively, and duly characterized before application.
Methods
The β-TCP/alginate microbeads were fabricated using droplet extrusion and ionotropic gelation, and integrated into secondary drug carrier HAp-K-PVA composite matrix, via freeze gelation. The physicochemical and thermal characterization of developed microbeads and matrix scaffolds was performed.
Results
When DOX and CDDP were co-loaded in DDS, a synergistic impact was observed after 30 days of continuous release, in contrast to the immediate outburst as seen with individual DOX and CDDP releases. Besides, the drug release from the microbeads only, the release with the HAp-K-PVA composite matrix scaffolds was observed slower. The controlled release, antibacterial effectiveness against the test pathogens and cell viability with osteoblast-like osteosarcoma (UTOS) cells indicated the therapeutic potential for the treatment of osteosarcoma in situ. The cell viability was observed for 24 h, which showed nearly 90% after 24 h for HAp-K-PVA composite matrix scaffolds, decreased for all the scaffold groups after 72 h, indicating the enhancement due to combined synergistic effect of the co-loaded drugs.
Conclusion
This study established a promising foundation for novel and sustainable biomaterials for osteosarcoma treatment. Further advancement holds the potential to enhance patient clinical outcomes and foster advancements in the field of regenerative medicine.
