A scientist conducting research on stem cells.
In the context of regenerative medicine, hematopoietic stem cells are essential precursors capable of generating all cell types found in the blood and the immune system. Through a process of continuous division and differentiation, these stem cells give rise to several specialized lineages:123
- Red blood cells (erythrocytes): Responsible for transporting oxygen throughout the body.2
- Platelets (thrombocytes): Critical for blood clotting and injury repair.2
- White blood cells (leukocytes): These include:
- Lymphocytes: Comprising T cells and B cells, which are central to the body's immune system and adaptive immunity.23
- Phagocytic cells: Including granulocytes and monocytes, which ingest and break down foreign particles and microorganisms.2
The differentiation of these cells is regulated by various colony-stimulating factors that respond to the body's physiological demands, such as infection or oxygen levels.2
