Immunohistochemical staining of infused human cells. Sections of human mitochondria were analyzed in bone marrow, lung, liver, kidney and spleen at day 1 (negative control group), day 2 and day 30 after human PDB-MSCs infused. No human cells were found in negative control group (a-e). At day 2 after 14C-TdR labeled PDB-MSCs infusion, PDB-MSCs were found in bone marrow, lung, liver, kidney and spleen (f-j). After 30 days,PDB-MSCs were found in bone marrow, lung, liver but not kidney and spleen (k-o). Human skin sections were stained as positive control (p). Scale bar = 100μm
