Abstract

In situ hybridization is used to survey the tissue-specific and developmental expression of the cloned mouse gene Sparc, coding for a protein homologous to the bovine Ca++-binding protein, osteonectin. High levels of SPARC RNA are found in osteoblasts and odontoblasts. In addition, high grain counts are associated with a variety of other cell types in the embryo and newborn mouse, including parietal endoderm, deciduum, whisker follicles (connective tissue sheath), peripheral nerve trunk, skin (dermis), and stomach (submucosa). Spatially restricted but high levels of SPARC mRNA are also seen in the adult adrenal glands, testis, and ovary. This pattern of differential gene expression demands a reassessment of the function originally proposed for osteonectin, and predicts a much wider role for the protein in a variety of biological processes.
