Chronic Inflammation May Enhance Leiomyoma Development by the Involvement of Progenitor Cells

Figure 6

Immunocytochemical analysis of α-SMA, collagen type 1, and fibronectin. Compared to the negative control (secondary antibody alone), the primary antibodies induce brownish staining in myometrium progenitor cells (MPCs) and leiomyoma progenitor cells (LPCs). The reaction was weaker for collagen type 1 than for α-SMA and fibronectin. Differences between MPCs and LPCs were not significant (immunoperoxidase, ×400 original magnification).
