There are reports describing similar mechanisms of pathogenetic development of ROP and BPD, in which a major role is played by inflammatory factors monocyte chemotactic protein 1 (MCP-1/CCL2), macrophage inflammatory protein 1 alpha (MIP-1α/CCL3), interleukin 6 (IL-6), macrophage inhibitory factor and angiogenne (fibroblast growth factor 1 (FGF-1) and the platelet-derived growth factor (PDGF) [29]. Here, FGF1 is linked to bronchopulmonary dysplasia.
