Megakaryocytes promote osteoclastogenesis in aging
Figure 7. Model showing OC stimulation by TPO and MKs in aging. The schema illustrates that aging increases MK number and alters MK-secreted factors, including RANKL, which together promote osteoclastogenesis. In addition, elevated TPO in the bone marrow cavity promotes direct and MK-mediated effects on OC formation in aged mice.
