Summary
Vascular progenitor cells can repair damaged arteries. These stem cells home to injury sites, engraft, and differentiate into mature endothelial cells, aiding vascular repair.
Area of Science:
- Cardiovascular Research
- Regenerative Medicine
- Cell Biology
Background:
- Vascular diseases share common features like endothelial dysfunction and inflammation.
- Mature endothelial cells can proliferate, but stem and progenitor cells also play a role in vascular repair.
Purpose of the Study:
- To review recent findings on stem/progenitor cells in vascular disease.
- To focus on the role of these cells in vascular repair processes.
Main Methods:
- Review of current literature on stem/progenitor cell research in vascular diseases.
- Analysis of studies demonstrating the reparative capabilities of endothelial progenitor cells.
Main Results:
- Endothelial progenitor cells from blood can repair damaged arterial endothelium.
- These cells originate from bone marrow, spleen, liver, fat, and arterial adventitia.
- Circulating progenitor cells are recruited to damaged areas by cytokines and platelets, then engraft and differentiate.
Conclusions:
- Vascular progenitor cells from various sources can repair damaged vessels.
- The local microenvironment is critical for progenitor cell homing and differentiation in vascular repair.

01:10Mechanism 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...
01:19Overview of Regeneration and Repair
Regeneration and repair processes are critical in healing damages caused by injury, disease, and aging. In regeneration, the damaged tissue is entirely replaced with new growth that restores the original architecture and function. In contrast, tissue repair usually results in a fixed tissue architecture involving scar formation. Scars generally do not reestablish tissue function and may also exhibit structural abnormalities at the injury site.

01:07Development 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...

01:24Regulation of Angiogenesis and Blood Supply
Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits. Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl hydroxylase and factor...
01:19Multipotency 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...
01:21Hematopoiesis
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...
