Rakhila et al. demonstrated a distinct cytokine expression profile favoring proliferation and angiogenesis for patients with endometriosis who showed increased levels of EGF, FGF-2, IL-1α, MIP-1β, transforming growth factor (TGF)-α, platelet-derived growth factor (PDGF)-AA, PDGF-BB, monocyte chemotactic protein 3 (MCP-3), soluble CD40 ligand (sCD40L), C-X-C motif chemokine ligand 1/2/3 (Gro Pan), IL-17α, macrophage-derived chemokine (MDC), and RANTES [27]. This evidence concerns the gene CCL7 and endometriosis.
