LGG cell free supernatant (LGG-SN) selectively reduces the viability of cancer cells in a concentration-dependent manner. Concentration–response plots for HT-29, HCT-116, Caco-2, A375 and Fibroblasts treated with increasing concentrations of LGG-SN (up to 90% v/v). MTT assay readout reveals a concentration dependent decrease of cellular viability in the four cancer cell lines, but not in Fibroblasts. Table reported in the bottom right summarizes the IC50 values (% of LGG-SN, v/v) and maximum effect (% viability) calculated per each cell type tested. N = 3. Values are presented as Mean ± SD
