Summary
The calcified cartilage of the dogfish vertebra has been studied by means of an undecalcified hard tissue method, including microradiography and tetracycline labelling, and electron microscopy. The transversely sectioned vertebra shows a centrum and neural and hemal arches. The mineralized area consists of a narrow but continuous band, which touches the perichondrium, and is formed by chondrocytes that participate in the mineralization of the surrounding matrix. The neural arches appear quite different; the upper parts contain an hypertrophied cartilage and, close to it, an inner zone formed by crescent shaped lamellar bone tissue containing osteoblasts and osteocytes. Tetracycline labelling of these two types of hard tissue reveals a globular calcification with calcospherites and Liesegang rings, at the level of the calcified cartilage, and a strong and linear label of the inner border of the osseous tissue. Transmission electron microscopy shows Type I collagen in the crescent shape area and Type II collagen in calcified cartilage area. The presence of osseous tissue in elasmobranch endoskeleton is discussed in relation to the evolution of the gnathostomes skeleton and the endocrinological control of calcium metabolism.
