Abstract The main aim of antineoplastic treatment is to maximize patient benefit by augmenting the drug accumulation within affected organs and tissues, thus incrementing drug effects and, at the same time, reducing the damage of non-involved tissues to cytotoxic agents. Mesenchymal stromal cells (MSC) represent a group of undifferentiated multipotent cells presenting wide self-renewal features and the capacity to differentiate into an assortment of mesenchymal family cells. During the last year, they have been proposed as natural carriers for the selective release of antitumor drugs to malignant cells, thus optimizing cytotoxic action on cancer cells, while More >

Abstract A series of the Guiqi polysaccharides/chitosan/alginate composite hydrogel microspheres (GPcM) with different particle sizes were prepared with Guiqi polysaccharides (GP), chitosan (CS) and sodium alginate (Alg). The optimum preparation process was also determined by single factor and orthogonal experiment analysis. The GPcM were characterized by fourier transform infrared spectroscopy (FT-IR), scanning electron microscope (SEM), drug loading efficiency test (LE), encapsulation efficiency test (EE) and in vitro release study. The results showed that the Guiqi polysaccharides chitosan hydrogel (GPCH) and sodium alginate hydrogel (SAH) formed a crossover system in GPcM. The GPcM have a uniform particle More >
