Understandably, lots of patients are worried about whether the body will reject foreign stem cells. However, mesenchymal stem cells are completely undifferentiated, meaning the body’s immune system doesn’t recognise them as ‘foreign’ when they are introduced.
Therefore, the risk of rejection is very low. Mesenchymal stem cells have been administered thousands of times by our doctors at Stemwell, with no instances of rejection. Lots of research has also documented that mesenchymal stem cells have a range of properties that help them to avoid rejection during cell therapy5.
We also screen and analyze stem cells rigorously before administration to ensure there is no chance of rejection and that they are safe for each patient.
