SELL and neoplasm: Intratumoral injection of STING agonists into tumor‐bearing mice (cGAMP or ADU‐S100) upregulated type I/II IFN genes, vascular stabilizing genes (including Angpt1, Pdgfrb, and Col4a), and adhesion molecules (including Icam, Vcam, and Sell), promoted tumor vascular normalization, reduced tumor hypoxia, and increased tumor‐specific CTL infiltration.287
