Characterization of Gnrh1^hpg/Gnrh1^hpg mice

hematopoietic system

increased bone marrow cell number ( J:19436 )

• bone marrow has a modest increase in total nucleated cells, accounted for by increases in B lineage lymphocytes

increased B cell number ( J:19436 )

• bone marrow and spleen have significantly more B cells, both immature and mature, than normal, and increasing serum estrogen decreases the number of B cells

increased immature B cell number ( J:19436 )

• in bone marrow and spleen

increased mature B cell number ( J:19436 )

• in bone marrow and spleen

abnormal splenic cell ratio ( J:19436 )

• splenic B cell population is approximately 2 fold higher than normal although no change is found in the number of Mac1 positive splenocytes

immune system

increased B cell number ( J:19436 )

• bone marrow and spleen have significantly more B cells, both immature and mature, than normal, and increasing serum estrogen decreases the number of B cells

increased immature B cell number ( J:19436 )

• in bone marrow and spleen

increased mature B cell number ( J:19436 )

• in bone marrow and spleen

abnormal splenic cell ratio ( J:19436 )

• splenic B cell population is approximately 2 fold higher than normal although no change is found in the number of Mac1 positive splenocytes
