(J:86202)
|
endocrine/exocrine glands
• fundic glands of the stomach contain abundant autofluorescent storage material
|
• cells contain abundant autofluorescent storage material
|
• enlarged, gelatinous and deeply pigmented, appearing orange to brown
• increase in the number of interstitial macrophages in the pancreas
|
• massive autofluorescence is seen in the exocrine cells of the pancreas but autofluorescence is absent from the islet cells
• however, no signs of exocrine pancreatic dysfunction are detected
|
• older mice (10 - 17 months) had zymogen granules replaced with large autofluorescent pigment granules
• no evidence of exocrine pancreas dysfunction, however
|
• interstitial cells of the Leydig in the testes are distended and inclusions in the cytoplasm are visible as brown pigment that is brightly autofluorescent
|
hematopoietic system
N |
• despite disruption of normal compartments for hematopoiesis, normal peripheral blood counts
|
• in older animals, evident in all spleens and some livers, with abundant neutrophilic and erythrocytic precursors and megakaryocytes

|
• seen in mice from 7 to 17 months of age
|
• evident in older mice, loss of follicles containing B cells
