TY - JOUR TI - Regulated changes in chondroitin sulfation during embryogenesis: an immunohistochemical approach. AU - Mark, M P AU - Baker, J R AU - Kimata, K AU - Ruch, J V T2 - The International Journal of Developmental Biology AB - Chondroitin sulfate proteoglycans, which represent the main class of nonfibrous macromolecules found in the extracellular matrix of connective tissues, have been implicated in the control of a variety of cell activities during ontogenesis. The respective contributions of the chondroitin sulfate chains and of the protein moiety of the proteoglycan in morphogenesis and cytodifferentiation are not known. In this context, monoclonal antibodies identifying specific chondroitin sulfate chains are interesting new tools. A panel of well characterized monoclonal antibodies recognizing distinct epitopes present only in chondroitin sulfate chains was used in conjunction with immunohistochemical techniques for the purpose of identifying and mapping chondroitin sulfate isoforms during development in the mouse and rat fetus. Expression of chondroitin sulfate isoforms occurred in the tissues according to specific spatio-temporal patterns, suggesting that chondroitin sulfates differing in sulfation position and degree perform distinct functions in development.
