Figure 239 from Chapter 7 (Mitochondria) of 'The Cell, 2nd Ed.' by Don W. Fawcett M.D. The cristae of mitochondria can take on zig-zag configuration (see arrows) which is particularly apparent in cel...

Mitochondria can show tremendous variation in size, even within a single cell. Here, a huge spherical mitochondria of about 6-7 µm in diameter is adjacent to small elongate mitochondria 0.5 µm wide...

The internal structure of mitochondria can change in response to physiological demand. Here, after the Sheepshead minnow Cyprinodon variegatus was kept in constant light for 4 weeks, mitochondria fro...

In the basal region of polarized epithelium engaged in ion transport, mitochondria are lodged between the interdigitating membranes of neighboring cells. This example is of a transverse section throu...

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...

Nuclear envelope and spindle dynamics when the nucleus moves into the neck of kar9delta mutant cells arrested in S phase. Movie plays at 100x real time and is movie S6 in Proc Natl Acad Sci. 2009. 10...

A monolayer of human foreskin fibroblast cells was infected with Toxoplasma gondii expressing YFP-tagged Tgalpha1tubulin and mRFP-tagged TgDLC (dynein light chain). Images acquired using API DeltaVisi...

Transmission electron micrograph of mitochondria from guinea pig pancreas. The use of osmium tetroxide as a fixative for electron microscopy was first described by Dr. Palade at the Rockefeller. Anot...
