Defective septation of right lung lobes in Fras1tm1Chpk/Fras1tm1Chpk embryos

respiratory system
• embryonic lung shows basement membrane distortions
• endothelial cells are locally detached from the basement membrane in the terminal sacs
• extravasation of erythrocytes into the embryonic respiratory lumen
• disarrangement of blood capillaries in the terminal air sacs of the lungs
• lobar septation defects are observed throughout embryogenesis and adulthood
• local disruptions of epithelial-endothelial contacts
• mutants exhibit completely or partially fused right lung lobes resulting from incomplete separation during development

cardiovascular system
• disarrangement of blood capillaries in the terminal air sacs of the lungs

• embryonic lung shows basement membrane distortions
• basement membranes between endothelial and epithelial type I cells in the lung appear wider and less dense compared with wild-type
