Figure 9. Depiction of rabbit BM before and after the arrest of B lymphopoiesis.

Figure 9

BM from <2-month-old rabbits is characterized by the presence of osteoblasts (support B lymphopoiesis) and B lineage progenitors. By 2–4 months-of-age the BM microenvironment transforms, and no longer supports B lineage development. The BM of >2-month-old rabbits fills with adipocytes and myeloid cells, which produce inflammatory mediators that specialize the BM for myelopoiesis.
