Collagen fibrils in the basal plate of Fundulus heteroclitus scales. The basal plate is made of thick collagen fibrils about 100 nm in diameter, which are organized into a plywood-like structure. Note...

Cell junctions formed between adjacent epidermal cells in Fundulus heteroclitus scales. Desmosomes line the membranes of two epidermal cells. A vast network of intermediate filaments and microfilament...

Rough endoplasmic reticulum and Golgi in epidermal cells of Fundulus heteroclitus scales. Epidermal cells undergoing advanced stages of scale development have prominent rough endoplasmic reticulum and...

Collagen fibrils and mineralization in the external layer of Fundulus heteroclitus scale. The external layer is the second of three layers closest to the dermis of an elasmoid. It is composed of thin ...

Rough endoplasmic reticulum and Golgi in the epidermal cell of Fundulus heteroclitus scale. Endoplasmic reticulum studded with protein-manufacturing ribosomes form a continuous network along the perip...

Low magnification of the epidermal region of the Fundulus heteroclitus scale. The epidermis is separated from the collagen layers of the dermis by the basement membrane. The cells of the epidermis (to...
