Integration of multi-modal imaging techniques and various cancer treatments based on their respective characteristics would be beneficial to enhance anticancer efficacy. Exploiting an “all-in-one” nanoparticle with high biocompatibility has attracted...
The delivery of therapeutic cancer agents via nanomaterials has received significant attention. However, because of the absence of tumour targeting, tumour treatment strategies are still not satisfactory. Umbilical cord mesenchymal stem cells are inherently prone to migrate to malignant
sites, enabling them to deliver antitumour drugs effectively. Therefore, it is expected to be a promising tool for tumour targeting. In this study, we constructed magnetic drug-loaded nanoparticles comprised of ferroferric oxide and doxorubicin, which were ingested by umbilical cord mesenchymal
stem cells and precisely delivered to the tumour sites. Here, we physicochemically characterized the nanoparticles for the particle size, biocompatibility and cellular uptake. The umbilical cord mesenchymal stem cells migration and homing ability before and after drug loading were evaluated.
The anti-cancer effect of stem cells loaded with nanoparticles was determined using MCF-7 cells. In vitro studies, the magnetic drug-loaded nanoparticles complex on tumour cells revealed that umbilical cord mesenchymal stem cells could transport magnetic drug-loaded nanoparticles to
induce robust apoptosis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
