Regulation of Angiogenesis and Blood Supply

2.9K
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...

Meristems and Plant Growth

Plants grow throughout their lives; this is called indeterminate growth, and it distinguishes plants from most animals. Although certain parts of plants stop growing (e.g., leaves and flowers), others grow continuously—like roots and stems.

Overview of the Vascular System01:20

Overview of the Vascular System

2.7K
The vascular system comprises an extensive network of arteries, capillaries, and veins. The vascular system can be broadly divided into the blood and lymphatic systems. Typically, blood vessels can be categorized into three histological regions: tunica intima, tunica media, and tunica adventitia. The tunica intima consists of a single layer of endothelial cells attached to the basal lamina. Underlying the basal lamina is a connective tissue layer and an elastic lamina that gives stability and...

Mechanism of Angiogenesis01:10

Mechanism of Angiogenesis

6.3K
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...

Development of Blood Vessels

2.0K
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...

Area of Science:

  • Physiology
  • Biophysics
  • Medical Imaging

Background:

  • Blood flow distribution in organs is complex and appears random.
  • Understanding this heterogeneity is crucial for diagnosing and treating various conditions.

Purpose of the Study:

  • To investigate the underlying principles governing flow distribution in the heart and lung.
  • To determine if fractal geometry can characterize this distribution.

Main Methods:

  • Analysis of flow heterogeneity across different scales.
  • Statistical analysis to identify patterns in flow distribution.
  • Application of fractal analysis to quantify system properties.

Main Results:

  • Flow distribution is heterogeneous but nonrandom, exhibiting statistically fractal properties.
  • A logarithmic relationship exists between flow dispersion and element size.
  • Near-neighbor correlation and spatial persistence were observed.

Conclusions:

  • The vascular system's branching structure contributes to fractal flow patterns.
  • Fractal analysis provides a framework for understanding organ growth and development.
  • This approach may minimize genetic material requirements for tissue engineering.
