Stem cells play a crucial part in repairing the human body by repairing damaged organs. These stemcells cannot repair tissue or organs when they cannot reach them in sufficient quantity.

  1. Free amount of stemcells in the blood.
  2. The flow rate of the blood
  3. How hard is it to reach the target location (eg; the organ we want to repair).
