Transmission electron micrograph showing collagen fibrils in longitudinal view from a patient with glaucoma. The a-e banding is visualized by uranyl acetate staining of charged amino acid residues in ...

Vorticella convallaria has a contractile stalk that arises from the aboral pole of the cell. The myonemes from the body converge at this pole and pass into the stalk to form a large contractile bundle...

Light micrograph of elastic cartilage of the ear. This type of cartilage is made from a protein called elastin and is formed from a network of elastic fibers and collagen. The fibers form bundles whic...

Light micrograph of elastic cartilage of the ear. This is a type of cartilage (connective tissue) that is present in the outer ear. It contains a network of collagen and elastin fibers, which gives it...

Scanning EM of a 24 hr (prim-5) Zebrafish embryo, showing the fibrous extracellular matrix connecting the mesoderm to the migrating neural crest cell. Specimens were chemically fixed critically poi...

High magnification scanning EM of the extracellular matrix of the notochord sheath. Specimens were chemically fixed critically point dried, and sputter coated with gold/palladium. This image is par...

Primary endothelial cells from transgenic mouse embedded in 3D collagen gels of ~ 100 Pa Young's modulus are exposed to 10 micromolar blebbistatin (myosin II ATPase inhibitor). Phase contrast time lap...
