Histology of kidney from conditioning start until day +21 post HSCT. No apparent abnormity in renal structure was observed after conditioning regimen (D 0) compared to untreated animals (D -7). Neither allogeneic, nor syngeneic transplanted mice developed any apparent changes detectable with histological examination at day +5, +7 and +21 (allogenenic group: A +5, A +7, A +21; syngeneic group: S +5, S +7, S +21). Day of stem cell injection is assigned as day 0 (D 0), days before and after stem cell injection are numbered with “-” and “+” sign, respectively. Hematoxylin and eosin staining, magnification ×20.
