Regulation of Angiogenesis and Blood Supply01:24

Regulation of Angiogenesis and Blood Supply

2.7K
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...

Mechanism of Angiogenesis01:10

Mechanism of Angiogenesis

5.8K
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...

Mesenchymal Stem Cells01:19

Mesenchymal Stem Cells

5.0K
Mesenchymal stem cells (MSCs) are adult stem cells that can differentiate into most connective tissue cell types, except for hematopoietic cells, depending upon the source of MSCs. For example, bone-marrow-derived MSCs (BM-MSCs) can differentiate into osteocytes, hepatocytes, and pancreatic and neuronal cells. MSCs can be isolated from various sources such as bone marrow, placenta, adipose tissue, teeth, and Wharton’s jelly, a gelatinous substance in the umbilical cord. The ease of their...

Area of Science:

  • Regenerative Medicine
  • Cardiovascular Research
  • Molecular Biology

Background:

  • Ischemic heart diseases, including myocardial infarction, are leading causes of death, often leading to chronic heart failure despite interventions.
  • Angiogenesis, the formation of new blood vessels, is crucial for restoring blood perfusion to ischemic tissues and preventing disease progression.
  • Stem cells offer therapeutic potential through differentiation or paracrine signaling, but their angiogenic regulation needs further understanding.

Purpose of the Study:

  • To evaluate the current data on how melatonin (mel) influences the angiogenic properties of stem cells.
  • To explore the potential of melatonin as an adjunct therapy in regenerative medicine for ischemic conditions.

Main Methods:

  • Systematic review and evaluation of existing scientific literature.
  • Analysis of studies investigating the effects of melatonin on stem cell-mediated angiogenesis.

Main Results:

  • Melatonin exhibits pleiotropic actions, including antioxidant, anti-inflammatory, and potentially pro-angiogenic effects.
  • Evidence suggests melatonin may modulate stem cell behavior to promote angiogenesis, although mechanisms are under investigation.
  • The review consolidates findings on melatonin's role in stem cell-based therapies for ischemia.

Conclusions:

  • Melatonin shows promise in enhancing stem cell-driven angiogenesis for treating ischemic diseases.
  • Further research into melatonin's mechanisms of action on stem cells could lead to novel therapeutic strategies for heart failure and other ischemic pathologies.
