Hematopoiesis

The formation of the formed elements of blood, including red blood cells, white blood cells, and platelets.

2
New cards

What is a haematopoietic stem cell (HSC)?

A multipotent stem cell in the red bone marrow that can differentiate into all types of blood cells, forming either myeloid or lymphoid lineages.

3
New cards

What are the two main lineages of blood cells derived from HSCs?

  • Myeloid lineage → RBCs, platelets, granulocytes, monocytes

  • Lymphoid lineage → B cells, T cells, NK cells

4
New cards

What is erythropoiesis?

The production of red blood cells (RBCs) in the bone marrow, stimulated by erythropoietin (EPO) from the kidneys in response to low oxygen levels.

5
New cards

What is leukopoiesis?

The production of white blood cells (WBCs) in the bone marrow, regulated by cytokines and growth factors.

6
New cards

How does erythropoietin (EPO) regulate RBC production (especially if O2 is low)?

The kidneys detect low oxygen → release EPO → stimulates erythropoiesis in the red bone marrow → increases RBCs → improves oxygen transport.

New cards

Key difference between erythropoiesis and leukopoiesis?

  • Erythropoiesis → RBCs, controlled mainly by EPO

  • Leukopoiesis → WBCs, controlled by cytokines and growth factors.
