Slfn14em1Nvm endonuclease-mediated mutation 1, Neil V Morgan MGI:7286186 |
||||||||||||
| Summary |
2 genotypes
|
|
|
| ♀ | phenotype observed in females |
| ♂ | phenotype observed in males |
| N | normal phenotype |
|
• no mice survive to weaning
• if pups survive beyond E14.5, they die shortly after birth
|
|
• E12.5 and E14.5 embryos are much more pale, with less vascular definition
|
|
|
| ♀ | phenotype observed in females |
| ♂ | phenotype observed in males |
| N | normal phenotype |
|
• splenomegaly is due to extramedullary erythropoiesis, the accumulation of mature erythrocytes, and hemolytic anemia
|
|
• increase in spleen weight and size
|
|
• mice show differences in erythroid progenitors in the spleen and bone marrow, indicating upregulation of erythropoiesis
|
|
• spleen is a secondary site for erythropoiesis; intermediate progenitors (EryBs) differentiate into mature erythrocytes (EryCs), which are highly populated within the spleen, suggesting erythroid maturation from the intermediate progenitor within the spleen
|
|
• increase in the proportion of proerythroblasts in the spleen
|
|
• mice exhibit microcytic erythrocytosis, an increase in erythrocyte count accompanied by a reduction in size
|
|
• lower hemoglobin levels
|
|
• mice exhibit microcytic erythrocytosis, an increase in erythrocyte count accompanied by a reduction in size
• irregularly shaped smaller erythrocytes (poikilocytes and microcytes)
• however, no difference in leukocyte counts
|
|
• mice show a 15% increase in the proportion of CD41+ SYTO13+ cells, indicating an increase in the proportion of immature platelets
• however, mice exhibit normal platelet function in response to major agonists thrombin, collagen, and collagen-related peptide and normal platelet adhesion and spreading
|
|
• increase in platelet size
• however, no difference in platelet count is seen
|
|
• almost 3-fold increase in megakaryocyte-erythroid progenitors
• however, megakaryocyte counts in spleen are normal and the proportion of megakaryocytes is unchanged
|
|
• following laser injury, mice form thrombi at a similar rate as controls, although they are smaller, with fewer platelets recruited, and embolize more quickly than in controls
• FeCl3 injury to the carotid artery results in occlusive thrombus formation as in wild-type mice, however mutants form thrombi at a slightly slower rate and have a tendency for reduced stability but not significantly
• however, mice exhibit normal bleeding times with tail tip excision and normal clot retraction
|
|
• splenomegaly is due to extramedullary erythropoiesis, the accumulation of mature erythrocytes, and hemolytic anemia
|
|
• increase in spleen weight and size
|
|
• splenomegaly is due to extramedullary erythropoiesis, the accumulation of mature erythrocytes, and hemolytic anemia
|
|
• increase in spleen weight and size
