Replica of a freeze-fractured gap junction presents the inner half-membrane on one of the cells (P-face, lower half of the micrograph) and the the outer half-membrane of the other cells (E-face, upper...

Freeze-fracture preparation of a continuous junction on the lateral surface of epithelial cells from the gut of a flea. Meandering ridges appear to be on the P-face of the replica. Figure 80, by Susu...

A murine macrophage phagocytosing a Leishmania parasite. Macrophages derived from the bone marrow of a C57/BL6 mouse were co-incubated in vitro with Leishmania mexicana (WHO strain MNYC/BZ/62/M379) st...

Scanning EM of a 24 hr (prim-5) Zebrafish embryo, fractured to reveal the neural tube, notochord and anterior faces of the myotomes. Specimens were chemically fixed critically point dried, and spu...

Scanning EM of the head folds. Specimens were chemically fixed critically point dried, and sputter coated with gold/palladium. This image is part of a series taken by Bryan Crawford while he was at ...

Rabbit psoas skeletal muscle fibers were held at constant length and rigor induced by immersion in glycerol. The fibers were quick-frozen by contact with a liquid helium- cooled copper block in a Heu...
