Therefore, encapsulation capacity, drug release, size, and the survival rate of cells with different concentrations of free and encapsulated AmB/ TEO were evaluated using the MTT method, and its antifungal activity was compared with conventional AmB.Results: Lipo-Niosome containing Tween 60 surfactant: cholesterol: Dipalmitoyl phosphatidylcholine (DPPC): Polyethylene glycol (PEG) with a ratio of 20:40:60:3 were chosen as optimal formulation. Lipo-Niosomes entrapment efficiency was %94.15. The drug release rate after 24 hours was %52, %54, and %48 for Lipo-AmB, Lipo-TEO, and Lipo-AmB/TEO, respectively. Physical and chemical characteristics of the Lipo-Niosomes particles indicated size of 200 nm and a dispersion index of 0.32 with a Zeta potential of -24.56 mv. Furthermore, no chemical interaction between drugs and nano-carriers was observed. The cell viability of adipose mesenchymal stem cells exposed to 50 μg/ml of free AmB, free TEO, and free AmB/TEO was %13.4, %58, and %36.9, respectively. Whereas the toxicity of the encapsulated formulas of these drugs was %48.9, %70.8, and %58.3 respectively. The toxicity of nanoparticles was very low (%8.5) at this concentration. Fluorescence microscopic images showed that the antifungal activity of Lipo- AmB/TEO was significantly higher than free formulas of AmB, TEO, and AmB/TEO.Conclusion: In this study, we investigated the efficacy of the TEO/AmB combination, in both free and encapsulatedniosomal form, on the growth of fungal infected-hASCs. The results showed that the AmB/TEO-loaded Lipo-Niosomes can be suggested as a new efficient anti-fungal nano-system for patients treated with hASCs. %U https://www.celljournal.org/article_253301_7de893970909dcfb247930d3ae5816d7.pdf
