mortality/aging
|
• lack of heart beat in some embryos at E11.5 and death at E12 to E12.5
|
integument
|
• collagen fibrils have diameters about 50% larger than wild-type fibrils
• however, E10.5 embryos have similar numbers of collagen fibrils as wild-type embryos
|
|
• embryos develop pallor at E11.5
|
cardiovascular system
|
• embryos show congestion of blood and an absence of clearly visible vasculature at E11.5

cardiovascular system
|
• 51% reduction of tensile strength (breaking strength) and a 59% reduction of elastic modulus (stiffness) of the ascending aortas
|
integument
|
• some collagen fibrils show irregular contours and a slight increase in fibril diameter in P50 skin with irregular fibril contour, but not increased fibril diameter, persisting at 15 weeks
|
|
• skin exhibits increased extensibility at high strain, but not low strain, at 15 weeks of age indicating reduced skin stiffness
|
|
• tensile strength of skin is reduced about 48% compared to wild-type skin
