Regulation of Angiogenesis and Blood Supply01:24

Regulation of Angiogenesis and Blood Supply

2.5K
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

5.3K
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...

    Summary

    Ketamine does not impact angiogenesis, including cell proliferation, migration, or capillary tube formation. This suggests ketamine may be a safe anesthetic option without affecting wound healing or angiogenic processes.

    Area of Science:

    • Cell Biology
    • Physiology
    • Anesthesiology

    Background:

    • Angiogenesis is crucial for wound healing and angiogenic therapies.
    • Understanding anesthetic effects on angiogenesis is vital for perioperative care.
    • Ketamine is a commonly used anesthetic agent.

    Purpose of the Study:

    • To investigate the effects of ketamine on in vitro angiogenesis.
    • To assess ketamine's impact on human umbilical vein endothelial cell (HUVEC) and normal human diploid fibroblast (NHDF) proliferation.
    • To evaluate ketamine's influence on HUVEC migration and capillary tube formation.

    Main Methods:

    • Assessed proliferation using a water-soluble tetrazolium salt reagent.
    • Quantified HUVEC migration via fluorescence measurement.
    • Examined capillary tube formation in cocultured HUVEC and NHDF with and without vascular endothelial growth factor (VEGF).

    Main Results:

    • Ketamine did not affect HUVEC or NHDF proliferation at tested concentrations (1, 10, 50 µM).
    • Ketamine showed no suppressive or enhancing effects on HUVEC migration.
    • No influence of ketamine on capillary tube formation was observed, even in the presence of VEGF.

    Conclusions:

    • Ketamine demonstrated no impact on in vitro angiogenesis models.
    • These findings suggest ketamine can be safely used as an anesthetic agent without compromising angiogenic processes.
