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 density of mitochondria can vary tremendously, depending on cell size and type. This image shows a dense cluster of mitochondria in the Golgi region of a Leydig cell of the domestic boar, Sus scr...

Mitochondria are localized in close proximity to a lipid droplet in a liver cell from a hamster fasted for four days, revealing an intimate metabolic relationship. Figure 254 from Chapter 7 (Mitochon...

Figures 220 (upper) and 221 (lower) from Chapter 7 (Mitochondria) of 'The Cell, 2nd Ed.' by Don W. Fawcett M.D. Mitochondrial density, and the number of cristae per mitochondrion are related to energ...

Figures 224 (upper) and 225 (lower) from Chapter 7 (Mitochondria) of 'The Cell, 2nd Ed.' by Don W. Fawcett M.D. Mitochondrial granules range in size from 25 - 120 nm and vary by tissue and physiologi...

Figures 242 (upper) and 243 (lower) from Chapter 7 (Mitochondria) of 'The Cell, 2nd Ed.' by Don W. Fawcett M.D. Examples of tubular-shaped cristae from mitochondria in the zona fasciculata of hamster ...

Figure 241 from Chapter 7 (Mitochondria) of 'The Cell, 2nd Ed.' by Don W. Fawcett M.D. The cristae of these mitochondria from Singh amoeba have a tubular appearance. Image by Tom Pollard. A PDF copy...

Steriod-secreting cells exhibit unusual diversity in the cristae of their mitochrondria, like these examples from testicular Leydig cells of the ground squirrel Citellus lateralis. Small alveolar cri...

Lipid droplets partially enveloped by mitochondria in the interstices between cardiac myofibrils reveal a metabolic partnership that can serve as an alternative energy source for muscle. Figures 255 ...

The inner segment of photoreceptors in the retina is packed with long, thin mitochondria that contain curved cristae. This image by Toichiro Kuwabara is of a photoreceptor from human retina, and appe...
