In this study, novel multicomponent microspheres (MCMs) with co-encapsulation and spatiotemporal drug release capabilities were developed for post-surgical liver cancer treatment and liver regeneration. The MCMs, fabricated via a microfluidic platform, consisted of a sodium alginate shell and gelatin methacrylate cores. The unique particle-in-particle structure allowed for the loading of doxorubicin (DOX) into the shell and augmenter of liver regeneration (ALR) into the cores, enabling rapid release of DOX and more sustained release of ALR. The dual-drug-loaded MCMs showed promising effects in postsurgical tumor killing and promoting liver regeneration, indicating their potential as versatile drug delivery systems for post-surgical cancer therapy.
Tumor recurrence after hepatic resection is a severe challenge of current liver cancer treatment. Here we present novel multicomponent microspheres (MCMs) with co-encapsulation and spatiotemporal drug release capabilities for post-surgical liver cancer treatment and liver regeneration. The MCMs were fabricated via a stepwise microfluidic platform and were composed of a sodium alginate (ALG) shell and gelatin methacrylate (GelMA) cores. Benefitting from the particle-in-particle structure, the MCMs provided the possibility of loading doxorubicin (DOX) and augmenter of liver regeneration (ALR) into the shell and the cores, respectively. Besides, the MCMs enabled rapid release of DOX and more sustained release of ALR. Therefore, the dual-drug-loaded MCMs exhibited prominent effects of postsurgical tumor killing and promoting liver regeneration. We anticipate that the present MCMs have remarkable potentials as versatile drug delivery systems for post-surgical cancer therapy.
