CHARACTERIZATION OF NANOPARTICLES CONDITIONED MEDIUM ADIPOSE TISSUE MESENCHYMAL STEM CELL (CM-ATMSC)

Abstract

Objective: The aims of this study were to formulate and characterize the nanoparticles containing conditioned medium adipose tissue mesenchymal stem cell (CM-ATMSC). Methods: Adipose Tissue Mesenchymal Stem Cell (AT-MSC) was cultured with supplemented Modified Eagle Medium (MEM) Alpha in an incubator with 37 °C and 5% CO2. The conditioned medium was collected when the cells were confluent. Nanoparticles were characterized in the term of morphology using transmission electron microscopy (TEM), particle size, zeta potential, loading capacity, entrapment efficiency, and drug release. Results: CM-ATMSC nanoparticles had the smallest particle size, namely chitosan-inulin nanoparticles with particle size of 128 nm, and the largest particle was modified chitosan (thiomer)-fucoidan nanoparticles with particle size of 254.3 nm. Based on zeta potential results, it is known that the resulting nanoparticle suspension was stable. Conclusion: The resulting nanoparticle suspension was stable and the smallest CM-ATMSC nanoparticle demonstrated the particle size of 128 nm. The results showed that the nanoparticles of CM-ATMSC have been successfully prepared.
