Abstract: | The tenascins are a family of multifunctional extracellular matrix glycoproteins subject to complex spatial and temporal patterns of expression in the course of various organogenetic processes, namely those involving epithelial-mesenchymal interactions. In the intestine, the tenascins, in particular tenascin-C, have been found to be differentially expressed in the developing and adult small intestinal and colonic mucosa as well as in neoplasm. While tenascin-C emerges as a key player likely to be involved in intestinal mucosa development, maintenance and disease, its exact role in the regulation of fundamental intestinal cell function(s) such as proliferation, migration and tissue-specific gene expression remains however to be established. |
