Nephroprotective Effect of Embryonic Stem Cells Reducing Lipid Peroxidation in Kidney Injury Induced by Cisplatin

Figure 6

Ratios of structural and compositional alterations obtained from spectroscopic analysis. Ratios related to membrane function, unsaturated lipid content, and lipid peroxidation from Fourier-transform infrared microspectroscopy (FTIRM) spectra of healthy mice and mice subjected to acute kidney injury (AKI) treated with isotonic salt solution (ISS) or mouse embryonic stem cells (mESC) at days 4 and 8 post-AKI. The ratios were as follows: (a) ratio assigned to protein/lipid (^-1), (b) ratio assigned to olefinic/total lipid (3013 cm^-1/(3013 + 2921 + 2854 + 1746 + 1457 cm^-1), (c) ratio assigned to olefinic/total CH₂ (3013 cm^-1/(2921 + 2854 + 1457 cm^-1), (d) ratio assigned to CH₂/CH₃ (^-1), and (e) ratio assigned to lipid peroxidation (^-1) (, , and ).
