Why is a bone marrow transplant used to replace defective lymphocytes in a patient?

Bone marrow creates common myeloid progenitor cells which differentiate into lymphocytes.

Bone marrow creates monocytes which differentiate into lymphocytes.

Bone marrow creates hematopoietic stem cells which differentiate into all immune cells including lymphocytes.

Verified step by step guidance

Understand the role of bone marrow: Bone marrow is a vital tissue in the body responsible for producing blood cells, including immune cells.

Identify the types of stem cells in bone marrow: Bone marrow contains hematopoietic stem cells, which are multipotent stem cells capable of differentiating into various types of blood cells.

Differentiate between myeloid and lymphoid lineages: Hematopoietic stem cells can differentiate into two main lineages: myeloid and lymphoid. Lymphocytes, which are crucial for the immune response, are derived from the lymphoid lineage.

Recognize the purpose of a bone marrow transplant: A bone marrow transplant is used to replace defective or damaged hematopoietic stem cells with healthy ones, allowing the production of functional immune cells, including lymphocytes.

Conclude the process: By transplanting healthy bone marrow, the patient can regenerate a functional immune system, as the new hematopoietic stem cells will differentiate into all necessary immune cells, including lymphocytes.
