Autoradiographies. Autoradiographies of organs frozen sections were realized after animals sacrifice, by 96 h after radiolabeled mesenchymal stem cells infusion. Lung images showed a homogenous repartition and the absence of radioactivity into main arteries that appeared in negative (A, arrows). Lonely signals on bone marrow cytospins confirmed the mesenchymal stem cells homing and excluded free indium bone uptake (B). In all cases no differences in repartition between control and hypoxic groups were observed (see tab. 1).
