Image analysis showed a higher proportion of CD68+ cells in NASH-STZ livers compared to all other groups (p < 0.05 or less, Figs. 5a and 4a, b) and double-staining with CD68 and Oil Red O revealed that CD68 + cells contained lipid species (see smallest insert in Fig. 4a). The gene discussed is CD68; the disease is metabolic dysfunction-associated steatohepatitis.
