Modifying Graft-versus-Host Disease in a Humanized Mouse Model by Targeting Macrophages or B-Cells

Table 3

Statistical analysis of histology and immunohistochemistry data in macrophage depletion. Mean survival with Standard Deviation (SD) values for histological and immunohistochemical scoring in macrophage-depletion experiments 1 and 2, each experiment comparing mice injected with huPBMCs with macrophage depletion by clodronate-containing liposome injection (liposomes+) and mice injected with huPBMCs without clodronate-containing liposome injection (liposomes-). The encountered effect related to liposomes injected is indicated with arrows indicating an associated increase or decrease of the mean histological infiltration scores.
