Title: Electron micrographs of autophagic vacuoles in striated muscle
Description:
(A, B): Autophagic vacuoles with remnants of mitochondria and glycogen particles. The most prevalent form of autophagy is called macroautophagy. In this process sarcoplasmic structures are sequestered in vesicles called autophagosomes that fuse with lysosomes for further breakdown and recycling of the macromolecules. Autophagic vacuoles or autolysosomes present as single membrane-bound bodies containing portion of sarcoplasm with organelles. The sequestered material is identifiable in various states of degradation and sometimes double membrane-structured elements are shown lining up these remnants.
(C): Perinuclear lipofuscin granules in the sarcoplasm. Note the difference with autophagic vacuoles. The electron-grey granules represent small lipid granules.
