Do you have data on this?

No significant benefit was seen after the intravenous infusion of 2×106 human MSCs 24 hours post-induction, which is most likely due to poor engraftment, entrapment in the alveolar capillary bed and/or immune rejection of the cells

Did you try to find an explanation for this? Did you do some histology / IHC to see what happened to the human MSCs in the rat?
