VEGFA and plasma cell myeloma: In contrast, treatment with pomalidomide + dexamethasone led to the production of the lowest level of VEGF compared to DCs alone or the PBS control groups (Figure 5D), suggesting that the combination therapy with DC vaccination + pomalidomide + dexamethasone suppressed angiogenesis by inhibiting VEGF production in the tumor microenvironment of myeloma-bearing mice.
