• Genetic Background: involves: 129P2/OlaHsd * C57BL/6

• ♀: phenotype observed in females
• ♂: phenotype observed in males
• N: normal phenotype

neoplasm

increased leukemia incidence ( J:150315 )

• the expansion of a monoclonal B cell population in a small percentage of mice is indicative of leukemia

increased chronic lymphocytic leukemia incidence ( J:150315 )

immune system

enlarged spleen ( J:150315 )

• spleen size is increased with age in a small percentage of mice

abnormal B cell morphology ( J:150315 )

• a small percentage of mice have a large population of monoclonal B cells that emerges with age

• these monoclonal B cells are larger in size and number, and have clumped chromatin with little cytoplasm

increased B cell number ( J:150315 )

• a small percentage of mice have increased B cells in the blood due to the emergence of a monoclonal population

lymph node hyperplasia ( J:150315 )

• about 60% of mice with a monoclonal B cell population display lymph node hyperplasia with numbers being up to 15 fold higher than controls

hematopoietic system

enlarged spleen ( J:150315 )

• spleen size is increased with age in a small percentage of mice

abnormal B cell morphology ( J:150315 )

• a small percentage of mice have a large population of monoclonal B cells that emerges with age

• these monoclonal B cells are larger in size and number, and have clumped chromatin with little cytoplasm

increased B cell number ( J:150315 )

• a small percentage of mice have increased B cells in the blood due to the emergence of a monoclonal population

growth/size/body

enlarged spleen ( J:150315 )

• spleen size is increased with age in a small percentage of mice
