Ventriclular abnormalities in Gata4tm1Jml/Gata4+ Gata5tm1Eem/Gata5tm1Eem and Gata4tm1Jml/Gata4+ Gata5tm1Eem/Gata5+ mice

mortality/aging
• mice do not survive past E14.5 with no live mice found in newborn litters

cardiovascular system
• fine, abnormal trabecular structures
• at E12.5, the thickness of the ventricular compact myocardial layer is reduced 61% compared to in wild-type mice
• at E14.5, the ventricular compact myocardial layer thickness is reduced 84% compared to in wild-type mice
• conotruncal cushions are reduced in size and altered in location compared to in wild-type mice leading to abnormalities in ventriculoarterial positioning
• endocardial cushions are hypoplastic at E12.5
• mice exhibit a primum atrial septal defect unlike wild-type mice
• mice exhibit a common atrioventricular canal and occasionally an unbalanced canal leading to a functionally univentricular heart
• mice exhibit large inlet-type ventricular septal defect
• mice exhibit moderately hypoplastic and anteriorly malaligned left ventricular outflow tracts
• the right ventricular outflow tract is more posteriorly positioned than in wild-type mice
• mice exhibit a thinning of the ventricular wall
• at E14.5, mice exhibit systemic hemorrhage
• proliferation of cells in the ventricular myocardium is reduced by 51% at E12.5 and 55% at E14.5 compared to in wild-type mice
• however, apoptosis rates are normal

homeostasis/metabolism
• at E14.5, mice exhibit body wall edema

muscle
• fine, abnormal trabecular structures
• at E12.5, the thickness of the ventricular compact myocardial layer is reduced 61% compared to in wild-type mice
• at E14.5, the ventricular compact myocardial layer thickness is reduced 84% compared to in wild-type mice
• proliferation of cells in the ventricular myocardium is reduced by 51% at E12.5 and 55% at E14.5 compared to in wild-type mice
