Deficiency of MIF Accentuates Overloaded Compression-Induced Nucleus Pulposus Cell Oxidative Damage via Depressing Mitophagy
Figure 8
MIF-KO accentuates oxidative stress-induced senescence of the NP cell via depressing mitophagy: (a) mitophagy in NP cells was determined by observation of GFP-LC3 and MitoTracker Red colabeled autophagosomes and mitochondria. (b) The electron micrographs of mitochondria and autophagosomes were observed via TEM, and double-membrane profiles resembling pieces of digested mitochondria were found in some autophagosomes in the high-compression loading group. Blue arrows represent the autophagic vacuole ultrastructural morphology. Red arrows represent the mitochondrial electron micrographs. (c) Statistic analysis of the mitolysosomes per field under optical microscopy (400x). . #.
