N normal phenotype
growth/size/body
• reduced body size, even at birth
• growth rate about 15% slower than normal

cardiovascular system
• exhibit significantly reduced carotid artery intimal hyperplasia in response to vascular injury and fewer intimal smooth muscle cells
• reduced neovascularization of implanted melanoma cells (J:46091)
• thickness of choroidal neovascular membranes was 31% lower than normal after treatment with krypton lasers (J:81029)
• left ventricular diameters did not increase as much after infarction as they did in controls
• better survival in the first 7 days after myocardial infarction than controls (90% survival as compared to 61%)
• exhibit impairment of smooth muscle cell migration through a gelatin-coated membrane towards a chemoattractant and in a wound assay

immune system
• earlier onset and increased severity of experimental autoimmune encephalomyelitis induced by immunization with myelin oligodendrocyte glycoprotein
• inflammatory cell infiltration and granulation tissue seen in response to implanted melanoma cells but to a lesser extent than in controls
• increased T-cell transmigration through the brain endothelium, dependent on the increased expression of Mmp9 seen in lymphocytes

neoplasm
• reduced tumor development after implantation of melanoma cells

nervous system
• increased T-cell transmigration through the brain endothelium, dependent on the increased expression of Mmp9 seen in lymphocytes

muscle
• exhibit impairment of smooth muscle cell migration through a gelatin-coated membrane towards a chemoattractant and in a wound assay

homeostasis/metabolism
• better survival in the first 7 days after myocardial infarction than controls (90% survival as compared to 61%)
