Figure 2. Decreasing the dose of radiation ameliorates radiation-induced pathology, but doesn't support xenoGVHD.
To determine the effect of radiation dose on xeno-GVHD, NSG mice were treated with either 50 or 200 cGray and administered PBS only or 30×106 PBMNC. Disease severity was measured by weight loss (A), clinical score (B) and survival (C). * denotes days when average weight or clinical score for 200rad + 30×106 PBMNC had p<0.05 compared to 200rad only. # denotes days when average weight or clinical score for 50rad only had p<0.05 compared to 200rad only. n= 5 mice per group.
