This report demonstrated that CD34+ hematopoietic stem cell (HSC)-derived allogeneic DCs engineered by an optimized lentiviral vector (LVV) expressing CD93, CD40-ligand (CD40L), and Chemokine (C-X-C motif) ligand-13 (CXCL13) significantly enhanced the host immune system, activated tumor-specific cytotoxic T cells, and led to complete regression of both primary and metastatic pancreatic tumors in humanized mouse models. This evidence concerns the gene CD93 and neoplasm.
