hematopoietic system
abnormal B cell differentiation ( J:120321 )
• after Poly(I) Poly(C) induction of cre expression in 6 week old mice, bone marrow shows 10 fold fewer pre-B cells, indicating a block in pre/pre-B differentiation
increased megakaryocyte cell number ( J:120321 )
• after Poly(I) Poly(C) induction of cre expression in 6 week old mice, 2 fold increase in megakaryocytes is observed
decreased B cell number ( J:120321 )
• after Poly(I) Poly(C) induction of cre expression in 6 week old mice, the total WBC count gradually decreases over a 6 week period resulting from a striking decline in peripheral B lymphocytes
decreased pre-B cell number ( J:120321 )
• after Poly(I) Poly(C) induction of cre expression in 6 week old mice, bone marrow shows 10 fold fewer pre-B cells
increased hematopoietic stem cell number ( J:120321 )
• after Poly(I) Poly(C) induction of cre expression in 6 week old mice, an increase in the hematopoietic stem cells and shift in progenitor fate toward granulocyte differentiation is observed
increased spleen red pulp amount ( J:120321 )
• after Poly(I) Poly(C) induction of cre expression in 6 week old mice, an expansion of the splenic red pulp is observed

immune system
