Popis: Stem cell therapy plays an important role in regenerative therapy; however, there is little information on the in vivo dynamics of transplanted stem cells and the influence of the inflammation of affected tissues or organs on these dynamics. In this study, we revealed real-time dynamics of transplanted adipose tissue–derived stem cells (ASCs) and the influence of the inflammatory states on these dynamics in acute liver failure mice. Quantum dots (QDs) labeling did not affect the cytokine profile of ASCs, and intravenously transplanted ASCs labeled with QDs could be detected in real time with high efficiency without laparotomy. Until 30 min after ASC transplantation, no marked differences in the behavior or accumulation of transplanted ASCs in the liver were observed among the three groups with different degrees of liver damage (normal, weak, and strong). However, significant differences in the engraftment rate of transplanted ASCs in the liver were observed among the three groups from 4 h after transplantation. The engraftment rate was inversely correlated with the extent of the liver damage. These data suggested that QDs are useful for in vivo real-time imaging of transplanted cells, and the inflammatory state of tissues or organs may affect the engraftment rate of transplanted cells.
