Fusion and fission of mitochondria7/31/2023 ![]() Sedat, Peter Walter, and their colleagues at UC San Francisco demonstrated The first experimental manipulations of mitochondrialįusion were conducted in model organisms. The combined effects of ongoing fusion and division give rise to Mitochondrial division is the breaking apart of one mitochondrialīody into two. Mitochondrial fusion is the physical merging of the outerĪnd then the inner mitochondrial membranes of two originally distinct Organelles, perhaps because early cell cross sections appeared to show manyĭistinct mitochondria, which we now know are often connected in a plane outside Textbooks still depict mitochondria inaccurately as small, static ovoid A mitochondrial network consists ofĪ complex, branched system of connected mitochondria (Figure 1). Mitochondrial networks in numerous cell types (reviewed Over subsequent years, many scientists described complex Networks in developing rat liver cells (Smithġ931). In 1931, Dorothea Smith observed variable mitochondrial Uncovering the genes, gene products, and mechanisms that control fusion and Mitochondrial dynamics is crucial for the health of the cell, and defects areĪssociated with several human genetic disorders.
