cellular
• dilated RER is observed in corneal endothelium of mice at 20 and 40 weeks
|
• abnormal accumulation of mitochondria in 20 week old mice
• presence of large amorphous regions in corneal endothelium of 40 week old mice
|
vision/eye
• corneal guttae (focal outgrowths) or Descemet membrane excrescences observed at 20 weeks of age
• guttae increase in number over time
|
• progressive decrease in cell density of corneal endothelial cells as compared to controls
• phenotype is more severe than in mice carrying the Col8a2tm2.1Asj allele
• 26% fewer cells at 20 weeks of age; 36% fewer cells at 40 weeks of age; 68% fewer cells at 80 weeks of age as compared to controls
• progressive increase in number of corneal endothelial cells that do not exhibit a hexagonal morphology
• by 80 weeks 2+/-5% of cells exhibit hexagonal shape
• dilated RER is observed in corneal endothelium of mice at 20 and 40 weeks
|
homeostasis/metabolism
• abnormal accumulation of mitochondria in 20 week old mice
• presence of large amorphous regions in corneal endothelium of 40 week old mice
