Figure 1.
Telomerase activity expressed in absorbance units (A450nm-A690nm) in the untreated cells or after treatment of PBMCs with 08AGTLF (Centella asiatica extract folmulation), Nutrient 4, TA-65, OA (oleanolic acid) and MA (maslinic acid). Error bars represent the standard deviation of the mean. Each mean was estimated from triplicate experiments. Asterisks indicate significant differences in the mean absorbance values measured after treatment with each activator compared with untreated cells (*P<0.05, **P<0.01, ***P<0.001 and ****P<0.0001) at the indicated concentrations.
