Figure 2.
Morphological characteristics and autophagic markers in ovaries and oocytes at 0–4 d.p.p. (a) An autophagosome (arrow) in the oocyte cytoplasm. TEM, scale bar: 200 nm. (b) Numerous mitochondria (arrows) in the oocyte cytoplasm. Lipid droplets (arrows) in the cytoplasm of a somatic cell around oocytes. TEM, scale bars: 1 μm. (c) WB for LC3-1 to LC3-2 in ovaries of 0–4 d.p.p. During autophagy, cytosolic LC3-1 is conjugated to phosphatidylethanolamine to form LC3-phosphatidylethanolamine conjugate (LC3-2), which is recruited to autophagosomal membranes. (d) IF for LC3B (red) and STAT3 (green) in 3 d.p.p. ovaries
