چکیده انگلیسی
Gene expression in human periodontal ligament (PDL) was examined by suppression subtractive hybridization to identify genes that are preferentially expressed in tissue compared to cultured PDL fibroblasts. The most enriched genes in a subtracted cDNA library are primarily genes for extracellular matrix components, types I and III collagen, lumican, periostin, and asporin, among others, whose expression conveys unique mechanical properties to the PDL. Also within this group is the gene for follicular dendritic cell secreted protein (FDC-SP), a small protein like statherin in saliva, not previously found in PDL. FDC-SP's presence in PDL was confirmed by in situ hybridization in mouse which also showed that it was definitely present in the parotid gland, but, surprisingly, not in the other salivary glands: submandibular and sublingual. Since only normal tissue was examined, these findings suggest that FDC-SP plays an important but previously unsuspected role within oral connective tissue.
