Bone Marrow and Stem Cell Transplant Program

Dr. Matthew Fero“Autologous bone marrow transplantation is the process of taking bone marrow stem cells out of a patient and then infusing them back in after the patient receives high dose therapy ... This allows us to use treatments that would otherwise harm the bone marrow.”

How it Works

“Because bone marrow is a liquid organ,” Fero says, “it can pass through an IV [intravenous] line.” Doctors rarely need to take stem cells directly out of the bone, Fero explains. They use drugs to coax bone marrow stem cells into the bloodstream. From there, the blood travels through an IV line into an apheresis machine that sorts the stem cells out and returns the rest of the blood. The experience is like donating blood at a blood bank.


Once stem cells are safely stored out of the bloodstream, doctors use high-dose chemotherapy to eradicate the remaining cancer. When chemotherapy is out of their system, the patients’ stem cells are reinfused. The process is similar to blood transfusion. Stem cells find their way back to bone marrow where they begin to grow and make new blood cells.

Bone marrow, the soft reddish material that fills the inside of our bones, produces millions of new blood cells each second. These millions of cells come from a tiny number of bone marrow stem cells. These stem cells are special because they can mature into all of the different types of cells in the blood. These are the cells doctors collect for a transplant.

Autologous bone marrow transplants are standard treatments for lymphoma and myeloma.

  • This treatment works very well against aggressive lymphomas. “In this case the goal is to cure the disease,” says Fero.
  • For multiple myeloma the goal of treatment is to extend people’s lives and give them a better quality of life.
