Induction of autophagy in MCF-7 cells as indicated by the percentage of LC3II protein. Cells were left untreated (5A), treated with, 50 nM (5B), or 100 nM (5C) Wort alone, or similar concentrations combined with MSC-CM (5D, 5E). “F” represents the relative changes in the level of the autophagy marker. Abbreviations: W: Wortmannin, S: MSC-CM, (***): P < 0.001, (*): P < 0.05, relative to the untreated cells
