TNFSF10 and neoplasm: This effect persisted up to 48 h, suggesting that the pIL6-TRAIL+-GFP+-UC-MSCs exhibit a higher survival rate in bone tissue compared to other organs in which these cells are cleared faster [20], while the reduction of the bioluminescent signal of the tumor burden at different time points and even 30 days after injection supported their MM cytotoxic activity.
