mortality/aging
• most mice die within a few hours of birth

muscle
• mice exhibit a defect in the number and localization of muscle progenitors at E12.5
• at E14.5, differentiating myofibers are aberrant and myofibers and Pax7+ and MyoD+ muscle progenitors are absent in localized regions
• the number of muscle progenitors is reduced by increased cell death and decreased proliferation
• 100% of mice develop multiple hernias throughout the diaphragm
• overt herniation of liver through the diaphragm first occurs at E16.5
• size and location of hernias vary, with 68% forming in the dorsal lateral diaphragm (Bochdalek hernias) and 32% developing in the ventral diaphragm (Morgagni hernias)
• hernias occur only in muscle-associated regions and not in the central tendon
• increase in the number of apoptotic cells in E12.5 embryos, many of which are present in regions that are abnormally devoid or muscle and consistently give rise to hernias
• decrease in the number of proliferative muscle progenitor cells in E12.5 embryos

homeostasis/metabolism
• mice exhibit low oxygen blood saturation

respiratory system
• defects in the lung lobar structure
• up to a 34% reduction in lung volume of lobes adjacent to hernias
