• bone marrow derived dendritic cells (BMDCs) cultured under hypoxic conditions (1% oxygen) show upregulation of maturation markers such as MHCII, CD86, with CD80 only slightly enhanced; control BMDCs grown in hypoxic conditions show similar enhanced maturation markers
• stimulation by LPS does not further enhance expression of maturation markers as it does in BMDCs grown under normoxic conditions
• production of Il12p70, Il10, Il6, and Il23 is decreased in mutant and control BMDCs under hypoxic conditions, with Il22 upregulated compared to normoxic cells; mutant and control BMDCs generated under hypoxic conditions produce less TNFalpha and Il-1beta than cells under normoxic conditions

• fewer mutant BMDCs generated under hypoxic conditions migrate toward CCL19 in a transwell chamber assay than control cells grown under hypoxic conditions; migration toward CXCL12 is not different from controls under hypoxic or normoxic conditions
• mutant BMDCs generated under hypoxic conditions injected into mouse footpads show reduced migration to popliteal lymph nodes compared to control BMDCs grown under hypoxic conditions; mutant and control BMDCs generated under normoxic conditions migrate equally well to draining lymph nodes while control cells generated under hypoxia display enhanced migration relative to control cells from normoxic cultures, indicating migration under under hypoxic conditons is dependent on Hif1a

|
• bone marrow dendritic cells (BMDCs) differentiated under hypoxic conditions display reduced growth (proliferation) compared to control cells grown in hypoxia or mutant and control cells grown under normoxic (21% oxygen) conditions

• reduced amounts of ATP are detected in lysates of mutant BMDCs cultured under hypoxic conditions compared to control cells under hypoxia suggesting an energy metabolism defect with Hif1a deletion

• fewer mutant BMDCs generated under hypoxic conditions migrate toward CCL19 in a transwell chamber assay than control cells grown under hypoxic conditions; migration toward CXCL12 is not different from controls under hypoxic or normoxic conditions
• mutant BMDCs generated under hypoxic conditions injected into mouse footpads show reduced migration to popliteal lymph nodes compared to control BMDCs grown under hypoxic conditions; mutant and control BMDCs generated under normoxic conditions migrate equally well to draining lymph nodes while control cells generated under hypoxia display enhanced migration relative to control cells from normoxic cultures, indicating migration under under hypoxic conditons is dependent on Hif1a
