In vitro experiments on the epithelioid sarcoma cell line, FU-EPS-1, and ST353i as human dermal fibroblast demonstrated an interaction between CD73 on fibroblast and CD147 (extracellular matrix metalloproteinase inducer, an imprint), performs a crucial part in controlling how much MMP2 is produced by activated fibroblasts. This evidence concerns the gene BSG and epithelioid sarcoma.
