Figure 5. Structural association of mitochondrial membrane with the ER called MAM, represented by HPF.
A) Abundant mitochondria within the cell, small connected vacuoles, and the connection of two chordoma cells with contact zones as well as excrescences (asterisk). B) Very close continuous contact zones of mitochondria (M) and ER. C) Connection of two chordoma cells with contact zones, excrescences (asterisk) and MAM complex.
