The stem cells used in a transplant are collected from the blood or sometimes the bone marrow. The first step in preparation for collection is to move the stem cells into the blood from the bone marrow using a process called mobilization.

Where are stem cells taken from?

Stem cells originate from two main sources: adult body tissues and embryos. Scientists are also working on ways to develop stem cells from other cells, using genetic “reprogramming” techniques.

Where do doctors harvest stem cells from?

The collection of stem cells from bone marrow has been safely performed for over 30 years. A bone marrow harvest is relatively simple and typically occurs in the operating room. During a bone marrow harvest, patients receive general anesthesia.
