Figure 8. Ultrastructure of rat arterial tissues (104×).
Tail veins of STZ-induced model rats (n=30 and 5 mice died or were not successfully modeled during STZ induction) were injected with liposomes containing different sequences (miR-15a-5p mimic, miR-15a-5p inhibitor or FASN shRNA) three times a week for 4 weeks. After 4 weeks, the thoracic aortas of each group rats (n=6 for each group) was isolated and fixed by osmium acid. The triangles represent lipid droplets; diamonds represent autophagosomes.
