Expression of versican and ADAMTS1, 4, and 5 during bone development in the rat mandible and hind limb.

ABSTRACT: Extracellular matrix (ECM) remodeling is achieved by both production and degradation of ECM molecules during bone development. ADAMTS (a disintegrin and metalloprotease with thrombospondin type 1 motifs) constitutes a family of extracellular proteases which are implicated in cleaving the protein versican. The present study was designed to investigate the expression of versican and ADAMTS1, 4, and 5 mRNA during bone development in rat mandibles and hind limbs by RT-PCR and in situ hybridization. Versican was localized by immunohistochemistry. The process of bone development from day 14 postcoitum through week 6 postnatum was divided into the beginning of osteogenesis, woven bone, and lamellar bone stages. Versican protein was abundant in the woven bone matrix, but decreased in the lamellar
