They stated that Fig 2D presents the fold change in tumor growth for hMSC-GFP treated mice relative to the untreated mice control, and that Fig 2E presents fold change in tumor growth for (UW426 +) hMSC-S-TRAIL treated mice relative to the (UW426 +) hMSC-GFP treated group. The gene discussed is TNFSF10; the disease is neoplasm.
