Combined Application of 17 𝛽 -Estradiol and Progesterone Enhance Vascular Endothelial Growth Factor and Surfactant Protein Expression in Cultured Embryonic Lung Cells of Mice

Figure 4

Quantitative analysis of VEGF gene expression in central lung fibroblasts treated for 48 hours with increasing concentrations of both E2 and P and with ICI/RU 486. Values were normalized against a housekeeping gene (HPRT) and expressed as % of controls. Note that the application of receptor antagonists 1 hour prior to hormone application (ICI/RU 486) antagonizes hormonal effects. control versus E2/P-8 M; control versus E/P-6 M.
