Although PGF transgenic mice did not have a baseline phenotype or a change in capillary density, they did exhibit a greater cardiac hypertrophic response, a greater increase in capillary density, and increased fibroblast content in the heart in response to pressure-overload stimulation. PGF transgenic mice showed a more adaptive type of cardiac growth that was protective against signs of failure with pressure overload and neuroendocrine stimulation.

Mechanistically, we show that PGF does not have a direct effect on cardiomyocytes but works through endothelial cells and fibroblasts by inducing capillary growth and fibroblast proliferation, which secondarily support greater cardiac hypertrophy through intermediate paracrine growth factors such as interleukin-6.\n            <\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>\n              <jats:underline>Conclusions:<\/jats:underline>\n            <\/jats:title>\n            <jats:p>PGF is a secreted factor that supports hypertrophy and cardiac function during pressure overload by affecting endothelial cells and fibroblasts that in turn stimulate and support the myocytes through additional paracrine factors.<\/jats:p>\n          <\/jats:sec>","DOI":"10.1161\/circresaha.111.240820","type":"journal-article","created":{"date-parts":[[2011,6,3]],"date-time":"2011-06-03T12:35:08Z","timestamp":1307104508000},"page":"272-280","update-policy":"https:\/\/doi.org\/10.1161\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":90,"title":["Placental Growth Factor Regulates Cardiac Adaptation and Hypertrophy Through a Paracrine Mechanism"],"prefix":"10.1161","volume":"109","author":[{"given":"Federica","family":"Accornero","sequence":"first","affiliation":[{"name":"From the Department of Pediatrics, Division of Molecular Cardiovascular Biology (F.A., J.H.v.B., M.J.B., J.D.M.), and the Howard Hughes Medical Institute (J.D.M.), University of Cincinnati, Cincinnati Children's Hospital Medical Center, Cincinnati, OH;
