Myeloid Stem Cells: What You Need to Know

A myeloid stem cell can transform into one of three types of mature blood cells. Red blood cells, carry oxygen to all tissues of the body. Platelets, which form blood clots to stop bleeding; and white blood cells or granulocytes, which combat infections and diseases.

According to an article by the National Cancer Institute of Spain. The functions of the primary immune cells and their origin are as follows. Hematopoietic cells, originating from the bone marrow, differentiate into two major lineages. The myeloid line and the lymphoid line. Each resulting cell type has one or more specific functions in the immune response.

The Scientific Perspective

In hematopoiesis, the terms “myeloid” and “myelogenous” describe blood cells that originate from a progenitor cell that gives rise to granulocytes, monocytes, erythrocytes, or platelets. The term “myeloid” frequently refers specifically to cells of the myeloblast lineage.

Although all blood cells, including lymphocytes, are born in the bone marrow, myeloid cells can be distinguished from lymphoid cells, which derive from common lymphoid progenitor cells that give rise to B and T cells. The differentiation of lymphoid cells isn’t complete until they migrate to lymphoid organs such as the spleen and thymus, where they are programmed through exposure to antigens.

White blood cells include myeloid cells associated with the innate immune system and lymphoid cells linked to the adaptive immune system. “Myelogenous” typically refers to non-lymphocytic white blood cells.

Further Clarifications

The term “erythroid” distinguishes “related to erythrocytes” from myeloid and lymphoid meanings. The word “myelopoiesis” has meanings parallel to those of “myeloid”. And myelopoiesis in the strict sense is the regulated formation of myeloid leukocytes, distinguishing it from erythropoiesis and lymphopoiesis.

The term “myeloid” can also mean “related to the spinal cord,” but this usage is rare. Myeloid should not be confused with myelin, an insulating layer covering the axons of many neurons. Myeloid neoplasms always concern the bone marrow and relate to hematopoietic cells.


Myeloid stem cells play a pivotal role in the body’s hematopoietic system. Giving rise to various types of mature blood cells that are essential for our health. These cells differentiate into red blood cells, which deliver oxygen to tissues throughout the body. Platelets, which assist in blood clotting and prevent excessive bleeding; and white blood cells or granulocytes which fight off infections and diseases.

The importance of myeloid cells goes beyond their immediate functions. They represent one of the two main branches of hematopoietic cells. With the other being the lymphoid lineage, which gives rise to cells involved in the adaptive immune response. This distinction between myeloid and lymphoid cells highlights the diverse ways in which the body’s immune system protects against both immediate and long-term health threats.

Understanding the nuances between terms like “myeloid,” “myelogenous,” and “myelopoiesis” is crucial in the field of regenerative medicine. The former refers to cells that originate from the bone marrow and contribute to the innate immune system. The latter describes the regulated formation of myeloid leukocytes, distinguishing it from erythropoiesis and lymphopoiesis. Additionally, myeloid neoplasms are a medical concern that relates directly to the bone marrow and hematopoietic cells.

Given the complex interplay of these cells and their functions, the role of myeloid stem cells is integral to maintaining overall health.
