ABSTRACT
Simultaneous presence of gelatinase A (MMP-2) and MMP-2 messenger RNA (mRNA) in 30 malignant tumors with various degrees of differentiation and biological behavior was evaluated by immunohistochemistry and in situ hybridization. The series consisted of 10 gastric carcinomas, 10 colorectal carcinomas, five squamous skin carcinomas, and five basal cell skin tumors. MMP-2 was detected in all cases. MMP-2 mRNA was expressed in the stromal cells in all cases and was more marked in the less-differentiated gastric and colonic carcinomas; it was also detected in the neoplastic cells of poorly differentiated tumors, particularly in those of the signet-ring cell type, both in the colon and stomach. The study confirmed that stromal cells have a specific role in tumor invasion and suggests a direct relationship between neoplastic epithelium and stromal cells in the most aggressive varieties.
