The effect of MEF on intracellular dehydrogenase activity. Dehydrogenase activity is expressed in relative units as the ratio of dehydrogenase activity of the treated group to the control group. Error bars represent standard error. The dashed line indicates a ratio of one (where values of the treated group are equal to the control group). * indicates significant difference from the control group, p < 0.05
