MMP11 and neoplasm: Similarly to other studies, our data show that MMP-11 (Stromalysin-3) was preferentially expressed by peritumoral stromal cells (Basset et al, 1990; Basset et al, 1997) and that high levels of MMP-11 were associated with tumour progression and poor prognosis (Chenard et al, 1996; Ahmad et al, 1998).
