Summary
Intermittent hypoxia (IH) affects engineered tissue vascular network formation. Hypoxic oscillation frequency significantly influences endothelial cells and fibroblasts in vitro.
Area of Science:
- Biomedical Engineering
- Cell Biology
- Physiology
Background:
- Engineered tissues require vascularization for survival and function.
- Intermittent hypoxia (IH) is a condition with potential impacts on tissue development.
- Understanding cellular responses to IH is crucial for regenerative medicine.
Purpose of the Study:
- To investigate the impact of intermittent hypoxia (IH) on the development of in vitro vascular networks.
- To characterize the role of hypoxic oscillation frequency in vascularization processes.
Main Methods:
- Utilized a combined experimental and mathematical modeling approach.
- Studied engineered tissues subjected to controlled intermittent hypoxia.
- Analyzed the vascular response of endothelial cells and fibroblasts.
Main Results:
- The frequency of hypoxic oscillations significantly influences vascular network formation.
- Endothelial cells and fibroblasts exhibit distinct responses to varying IH frequencies.
- Mathematical modeling provided insights into the dynamics of vascularization under IH.
Conclusions:
- The frequency of intermittent hypoxia is a critical factor in engineered vascular network formation.
- Cellular responses, particularly of endothelial cells and fibroblasts, are modulated by IH frequency.
- This study provides a foundation for optimizing IH conditions in tissue engineering.

01:24Regulation of Angiogenesis and Blood Supply
4.0K
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...

01:10Mechanism of Angiogenesis
7.8K
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...

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...

01:23Hypoxia
2.7K
Hypoxia is a medical condition characterized by an inadequate oxygen supply to body tissues. It typically manifests as a bluish discoloration of the skin and mucosae, especially in fair-skinned individuals, when hemoglobin (Hb) saturation drops below 75%.
Types of Hypoxia
There are four primary types of hypoxia, each resulting from a different cause:
1. Anemic hypoxia: This type occurs due to insufficient oxygen delivery caused by a lack of red blood cells (RBCs) or RBCs with abnormal or...

01:17Autoregulation of Blood Flow
10.2K
Autoregulation mechanisms are characterized by their inherent capacity for self-regulation without necessitating specific nervous stimulation or endocrine control. These mechanisms facilitate the adjustment of blood flow and, therefore, perfusion specific to each tissue region. This self-regulation encompasses chemical signals and myogenic controls.
Chemical Signaling in Autoregulation
Chemical signaling operates at the precapillary sphincter level, inciting either contraction or relaxation....

01:15Structure of Blood Vessels
13.1K
Blood is circulated throughout the human body through a network of blood vessels called the circulatory system. This system includes arteries that transport blood from the heart to various body parts. These arterial pathways divide into smaller vessels until they reach the arterioles, which further split into capillaries. It is within these minuscule capillaries that the exchange of nutrients and waste products takes place. After this exchange, the blood is collected by venules, which fuse to...
