Fig. 3From: Differential inhibition of gelatinase activity in human colon adenocarcinoma cells by Aloe vera and Aloe arborescens extractsHT29 cell proliferation assay. Cells were exposed for 48 h to A. arborescens or A. vera extracts prepared with 50% (v/v) MetOH (methanol). Cell growth was obtained by the standard MTT assay. Results are expressed as the mean of at least three replicate experiments ±SD.*p < 0.05 between concentrationsBack to article page
