Abstract

Tenascin mRNA expression was studied by an in situ hybridization method in 27 skin tumors. Tenascin synthesis was increased in all skin tumors when compared to uninvolved skin but there was variation in the site of cellular synthesis between different types of tumors. In melanocytic nevi and precancerous keratinocyte lesions, tenascin seemed to be of epidermal or stromal origin. In basal cell carcinoma, squamous cell carcinoma and malignant melanoma, there was tenascin synthesis also in tumor cells. These findings are in concordance with earlier studies which suggest a role of tenascin as an anti-adhesive and motility-promoting factor in malignant skin tumors.
