It has been shown that MSC secrete high amounts of cytokines, which induce inhibition of tumor growth in vivo in breast cancer cells, such as IFN-α, DKK-1/3, IL12, TRAIL, TNFSF14 (also known as LIGHT), FLT-3 ligand, CXCL10, and LAP [64,65,66,67]. This evidence concerns the gene TNFSF14 and breast carcinoma.
