Mitochondria are in contact, or tethered, to ICDs. Portions of serial block face SEM images for control ICDs showing examples where a mitochondrion is (A) in contact with a gap junction in the interplicate region (arrow) and (B) tethered to the tip of a plicate fold (arrow). (C and D) 3D reconstruction of the mitochondrion and ICD showing in (C) how the ICD forms a basket shape in which the mitochondrion (green) sits in and (D) where the ICD wraps around one end of a mitochondrion (magenta). Scale bar = 1 μm. To see this figure in color, go online.
