Immunohistochemically, 14-3-3β (Fig. 5A and 5B) and mimecan (Fig. 5C and 5D) were localized in leiomyoma and myometrial smooth muscle cells, connective tissue fibroblasts and vascular cells, with a considerable variability in their intensity among these cells within the same tissue (Figs. 5). Here, OGN is linked to leiomyoma.
