Fig. 2From: Postbiotic metabolites produced by Lactobacillus plantarum strains exert selective cytotoxicity effects on cancer cellsAntiproliferative effect of 30% (v/v) of PM produced by six strains of Lactobacillus plantarum on (a) MCF-7 cells and (b) HT-29 cells determined by BrdU cell proliferation assay. Values within the same row and experiment having an asterisk indicate significant differences (P < 0.05) from the untreated control groups. Error bars represent the standard error of the mean of nine replicatesBack to article page
