Hematopoietic Stem Cells vs. Progenitor Cells: What's the Difference?
Edited by Aimie Carlson || By Harlon Moss || Published on February 18, 2024
Hematopoietic stem cells (HSCs) are multipotent cells forming all blood cells; progenitor cells are derived from HSCs, more differentiated but less versatile.
Key Differences
Hematopoietic stem cells are multipotent, capable of developing into various types of blood cells. Progenitor cells, derived from these stem cells, are more differentiated and have a narrower potential in terms of the cell types they can become.
Hematopoietic stem cells are the primary source of all blood cell types, maintaining blood cell production throughout life. Progenitor cells are an intermediate stage, where they have committed to developing into specific types of blood cells but have not yet fully differentiated.
Hematopoietic stem cells possess the unique ability to self-renew, creating identical copies of themselves. Progenitor cells have limited or no self-renewal capacity, moving closer to becoming mature blood cells.
Hematopoietic stem cells are used in transplants to treat various blood disorders, as they can regenerate the entire blood system. Progenitor cells, being more specialized, have more targeted applications in therapy, such as in regenerative medicine for specific cell types.
Hematopoietic stem cells are found in the bone marrow, umbilical cord blood, and peripheral blood. Progenitor cells are primarily located in the bone marrow, where they continue to differentiate into mature blood cells.
