Figure 4From: Hepatoprotection and neuroprotection induced by low doses of IGF-II in aging ratsMitochondrial Membrane Potential (MMP) in isolated liver mitochondria by flow cytometry. MMP is considered a good marker of mitochondrial function [32] which is assessed under different substrates. Mitochondria from untreated aging rats (O group) showed a significant depletion of MMP in all conditions. AUF, arbitrary units of fluorescence.Back to article page
