Antibody-Targeted Bismuth Gadolinium Nanoconjugate for Image-Guided Radiotherapy of Hepatocellular Carcinoma.

Hepatocellular carcinoma (HCC), one of the most lethal cancers of the liver, has limited treatment options at advanced stages. Here, bismuth gadolinium (BiGd) nanoparticles (NPs) conjugated with anti-vascular endothelial growth factor antibody (aVEGF) are designed and tested for targeted image-guided radiation therapy against HCC. The BiGd NPs are synthesized using the sol-gel technique, functionalized with silica NPs, and labeled with fluorescent protamine-rhodamine B.

Integration of Electrospun Scaffolds and Biological Polymers for Enhancing the Delivery and Efficacy of Mesenchymal Stem/Stromal Cell Therapies.

Mesenchymal stem/stromal cells (MSCs) have emerged as a promising therapeutic approach for a variety of diseases due to their immunomodulatory and tissue regeneration capabilities. Despite their potential, the clinical application of MSC therapies is hindered by limited cell retention and engraftment at the target sites. Electrospun scaffolds, with their high surface area-to-volume ratio and tunable physicochemical properties, can be used as platforms for MSC delivery.
