Abstract
To test whether cartilage bones and dermal bones, which belong to two different units of the vertebrate skeleton, have distinct developmental programs possibly reflected in a different molecular control of their ossification process, we currently investigate the development of some selected cranial bones in the zebrafish, Danio rerio. Here we present some light microscopical and ultrastructural findings with respect to the maxillary bone (a dermal bone that is edentulous in the zebrafish) and the basioccipital bone (a cartilage bone, i.e., with a perichondral phase followed by endochondral invasion). The two bones differ in (a) the area where matrix is first deposited--an unstructured extracellular domain in the former versus intermingling of bone matrix elements with cartilage matrix in the latter--and (b) the progression of ossification--continuously from an initium in the former versus through fusion of separate anlagen in the latter. These findings seem to support the hypothesis that the two types of bone have at least some distinctive features in their developmental programs.
