Super Fast Healing?

Recently a team of researchers from the Imperial College London discovered a way to release a lot of certain stem cells which could help heal injuries faster. They were trying to release endothelial progenitor cells into the body of a rat by injecting proteins but ended up also releasing mesenchymal stem cells, which help endothelial progenitor cells repair tissue. I think that this is a great step forward and could really help people recover faster from injuries. However, I also believe that they should test this very carefully before testing it on humans because so far it has only been tested on rats. All in all, I believe that this is a very important discovery.
