Insights

Endothelial progenitor cells (EPCs) are crucial for cardiovascular health, but their unclear definition hinders clinical use. This review clarifies EPC characterization and mobilization for better cardiovascular disease management.

Area of Science:

  • Cardiovascular Research
  • Cell Biology
  • Regenerative Medicine

Background:

  • Endothelial progenitor cells (EPCs) play a role in vascular repair and are linked to cardiovascular risk.
  • Mobilization of EPCs can be influenced by various physiological and pathological factors.
  • Circulating EPC levels serve as predictors for cardiovascular events and cardiac remodeling post-myocardial infarction.

Purpose of the Study:

  • To review current knowledge on endothelial progenitor cell (EPC) characterization and mobilization.
  • To address the uncertainties and lack of a definitive EPC definition.
  • To explore the potential role of EPCs in managing cardiovascular diseases.

Main Methods:

  • Literature review of current research on EPCs.
  • Analysis of studies on EPC mobilization and characterization.
  • Synthesis of information regarding EPCs in cardiovascular pathophysiology.

Main Results:

  • The definition and identification of EPCs remain inconsistent, complicating research and clinical application.
  • Factors influencing EPC mobilization are diverse, including drugs and disease states.
  • Despite definition challenges, EPCs show prognostic value in cardiovascular conditions.

Conclusions:

  • Clarifying EPC definition and standardization is essential for clinical translation.
  • Understanding EPC mobilization mechanisms is key to harnessing their therapeutic potential.
  • Further research is needed to establish EPCs as reliable biomarkers and therapeutic targets in cardiovascular medicine.

Mechanism of Angiogenesis01:10

Mechanism of Angiogenesis

Blood vessel formation starts early during embryonic development, around day 7. In the extraembryonic yolk sac, mesodermal precursor cells called hemangioblast proliferate and differentiate into angioblast. Angioblasts express vascular endothelial growth factor receptor 2 or VEGFR2, which binds VEGF-A, a proangiogenic factor, guiding blood vessel formation. VEGF signaling promotes angioblasts to form a blood island in the developing embryo. Angioblasts further differentiate, giving rise to...
Hematopoiesis01:21

Hematopoiesis

The process of blood cell formation is called hematopoiesis. Hematopoiesis starts early during development, on the seventh day of embryogenesis. This phase of hematopoiesis is called the primitive wave, wherein the extraembryonic yolk sac allows the production of erythroid cells and endothelial cells from a common precursor called hemangioblast. The erythroid cells provide oxygen to support the growth of the rapidly dividing embryo. Hemangioblasts later develop into hematopoietic stem cells or...
Multipotency of Hematopoietic Stem Cells01:19

Multipotency of Hematopoietic Stem Cells

The hematopoietic stem cells or HSCs are multipotent, meaning they can differentiate and give rise to all blood and immune cells. HSCs are maintained in the quiescent stage until an external stimulus initiates their differentiation. The multipotent HSCs exist as two heterogeneous populations, long-term repopulating cells (LTRC) and short-term repopulating cells (STRC). The two HSC populations have different surface markers or receptors and are classified based on quiescence and long-term...

Production of Formed Elements01:34

Production of Formed Elements

Hemangioblasts are multipotent stem cells originating from the mesoderm. They give rise to hematopoietic stem cells (HSCs), which undergo hematopoiesis to produce all the formed elements of blood. This process is regulated by a complex network of hematopoietic growth factors, including transcription factors, growth factors, and cytokines. These factors stimulate the HSCs to divide and differentiate, though some HSCs remain undifferentiated to maintain a self-renewing pool.
Most HSCs commit to...
Development of Blood Vessels01:07

Development of Blood Vessels

The development of the vascular system in a fetus is a complex and intricate process that begins as early as 15 to 16 days post-conception. This process starts outside the embryo, specifically in the mesoderm of the yolk sac, chorion, and connecting stalk. Approximately two days later, the formation of blood vessels occurs within the embryo itself.
The initial formation of this system is facilitated by the small amount of yolk present in the ovum and yolk sac. Blood vessels originate from...
