Defects in the skin, lung and intestine of Egfrwa2/Egfrwa2 Ptpn11tm1Paw/+ mice

mortality/aging
• only 30% survive to weaning, with most dying within 7-10 days after birth

growth/size/body
• exhibit progressive wasting

muscle
• lumen of stomach and small and large bowels are filled with desquamated epithelial cells, suggesting lack of peristalsis
• decrease in the size of subcutaneous muscle tissue

respiratory system
• lungs are immaturely developed with poorly inflated areas
• increase in thickness and cell masses of the alveolar septae
• display breathing difficulties

vision/eye

adipose tissue
• decrease in the size of subcutaneous fat tissue

digestive/alimentary system
• the muscle layer of the bowel is poorly organized and is decreased in thickness
• lumen of stomach and small and large bowels are filled with desquamated epithelial cells, suggesting lack of peristalsis

integument
• decrease in the size of subcutaneous fat tissue
• little hair outgrowth
• poorly developed hair follicles
• hair follicles are disordered
• skin contains no or few disorganized hair follicles
• hypotrophy in the epidermis
• skin gradually becomes dry and flaky
• skin gradually becomes dry and flaky
