Compared to hAT-MSC-CM, hUCT-MSC-CM contains high levels of factors which induce apoptosis of tumor cells (tumor necrosis factor superfamily member 14 (TNFSF14) and promote anti-tumor Th1 cell-mediated immune response (C-X-C motif chemokine ligand (CXCL)10 and Fms-related tyrosine kinase 3 ligand) [37]. This evidence concerns the gene FLT3LG and neoplasm.
