A lattice arrangement of mitochondria is rare in vertebrate cells, but can be observed here in mature Sertoli cells of the Xenopus testes. Multiple parallel fenestrated layers of cristae are interconn...

The midpiece of spermatzoa in nearly all vertebrates is enclosed in a sheath of mitochondria, which provide a ready source of ATP necessary for sperm motility. Here, a longitudinal section through sp...

The contractile vacuole of Coleps hirtus. The filled CV is continuous with tubules of the smooth spongiome. The tubular nature of mitochondrial cristae is particularly evident in this micrograph. Stan...

High resolution micrograph of the contractile vacuole of Coleps hirtus. The filled CV is continuous with tubules of the smooth spongiome. The tubular nature of mitochondrial cristae is particularly ev...

Sec63-mCherry in BY4742 sac1∆ vps74∆ highlights nuclear ER and cortical ER and/or PM. This image is the control image labeling ER for overlay with GFP-Vps74 (CIL# 24812) demonstrating that in the ...

Tubules within the cristae of mitochondria can sometimes take on unusual configurations. Here, in the upper panel, a mitochondrion from an astrocyte in hamster brain appears to have prismatic tubules...

The decorated spongiome of the CVC is composed of 50nm tubules that have a pattern of helically wound subunits attached to their cytosolic surfaces. These tubules can be up to one micrometer or more i...

High resolution micrograph of cubic membrane array which represents the cell’s method of storing large quantities of lipid and protein bilayers into the smallest possible volume. These membranes can...

A partially filled contractile vacuole is connected to two regions of spongiome tubules. The extra CV membrane is acquired from these spongiomes. Presumably some of these spongiome tubules are decorat...

A high resolution view of the Contractile Vacuole Complex. The CV membrane has collapsed into regularly spaced tubules oriented perpendicular to the microtubular ribbon in this ruptured cell. Some tub...
