Several lines of evidence suggest that platelet-derived growth factor A chain (PDGF-A) is required for normal embryonic cardiovascular development. To test this directly, we introduced anti-PDGF-A neutralizing antibodies into mouse deciduas in utero at Embryonic Days (E) 8.5, 9.5, and 10.5. This resulted in the selective disruption of PDGF-A ligand-receptor interactions in vivo for a period of 18-24 hr and allowed us to assess both if PDGF-A is required for cardiovascular development and when it is required. Embryos collected 48 hr after antibody treatment displayed severe cardiovascular abnormalities. These included both atrial and ventricular myocardial hypertrophy, epicardial and endocardial abnormalities, and aortic dilation, among others. Although heart abnormalities were observed in embryos treated at all three ages, they were more common in embryos treated at E8.5. In contrast, only embryos treated at E10.5 exhibited significant aortic dilation. This work (1) demonstrates directly for the first time that PDGF-A is required for normal cardiovascular development, (2) identifies several processes that require PDGF-A, and (3) defines discreet developmental periods during which these PDGF-A-dependent processes require the factor.
