BMAds are important contributors to systemic adipokine levels (12), as well as regulators of bone (13) via RANKL expression (14) and hematopoiesis via stem cell factor (SCF) production (15), and have recently been implicated in bone metastatic cancers such as acute myeloid leukemia (16) and breast cancer (17). Here, KITLG is linked to acute myeloid leukemia.
