GVHD scores of lung, colon, spleen, and skin. Recipients of 0.5 × 106 (high) or 0.1 × 106 (low) MSC and control recipients were killed for histological examination. Sections taken from lung, colon, and spleen were scored on a scale of 1–4 with 4 being the most severe changes consisting of tissue destruction observed in GVHD. Skin was scored on a scale of 1–3, with 3 being the most severe. This experiment was repeated three times (n=3 per group).
