Transmission electron micrograph of continuous endothelium from the capillary of a rat tongue. Image made available by James D. Jamieson and the Department of Cell Biology, Yale University School of ...

Transmission electron micrograph of rat capillary diaphragm 2h post intravenous administration of ferritin. Ferritin is seen entering plasmalemmal vesicles and into the extracellular space. Image mad...

Transmission electron micrograph of a discontinuous endothelium in a capillary from a guinea pig pancreas. There is a red blood cell in the capillary lumen and a pericyte under the endothelium. Imag...

Transmission electron micrograph of surface of nuclear envelope of guinea pig spermatocyte prepared by the Freeze-fracture technique shows the unusual clustering of nuclear pores in these cells. From...

Figure 275 from Chapter 8 (Lysosomes) of 'The Cell, 2nd Ed.' by Don W. Fawcett M.D. Lysosomes of cells engaged in heterophagy, like the Sertoli cells from the testis of the chinchilla shown here, are...

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...
