  Bone marrow is the soft tissue inside the bones.
  
  To replace the marrow, the bone marrow in your body is first destroyed say with radiation.
  
  Then using a tube (for example the one they insert in a patient to collect blood ) new cells are injected in your bloodstream.
  
  The cells will find their way to the bloodstream and grow to healthy bone marrow.
  
  It’s similar to being given medicine via a tube into your body.

  I agree with Peter, Bone marrow transplant is however an option if stem cell transplant is impossible; i.e collecting undifferentiated cells from the blood rather than marrow

  Yup- as others have said, first the sick marrow has to be killed/removed. This will be achieved via chemotherapy (chemo) with or without radiation. Then, healthy cells are given to the patient using an intravenous (IV) line, or tube. The cells find their way into your marrow, where they grow and start to make healthy red blood cells, white blood cells and platelets.
