Endothelial cells and megakaryocytes in advanced cIMF were prominently stained for MMP-14 (MT1-MMP) protein. A: Labeling of endothelial cells (arrows) was demonstrable in extended sinusoids (arrows) along with staining of clustered megakaryocytes and also immature granulopoiesis. B: Normal hematopoiesis showed heterogeneously labeled megakaryocytes and also occasionally granulocytic precursors. Original magnifications: ×400 (A); ×100 (B).
