CD10-positive Stromal Cells in Gastric Carcinoma: Correlation with Invasion and Metastasis

Abstract

Background: CD10 is a cell surface metalloproteinase expressed by a variety of normal cell types, including lymphoid precursor cells, germinal center B lymphocytes and some epithelial cells. Although accumulating data indicate that CD10 expression by stromal cells is involved in colorectal carcinogenesis and it is a novel prognostic factor in breast carcinoma, CD10-positive stromal cells and their correlation with invasion and metastasis have not been studied in gastric carcinoma. The aim of this study was to immunohistochemically investigate the rate of CD10 production in the stromal cells in our gastric carcinoma collection and clarify its correlation with invasion and metastasis.
