Mechanism of Angiogenesis

Mechanism 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...

Regulation of Angiogenesis and Blood Supply

Regulation 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...

Background:

Tissue engineering aims to create complex, multi-tissue organs.
Optimizing cell differentiation and phenotype maintenance is crucial for engineered tissues.
The angiogenic process is key for vascularizing engineered constructs.

Purpose of the Study:

To develop prototype tissue engineered matrices supporting simultaneous growth of diverse cell types.
To investigate matrix compositions promoting vascular and tube formation.
To create an in vitro cornea-sclera model with innervation and vascular structures.

Main Methods:

Examined fibrin-based and collagen-based matrix compositions.
Incorporated growth factors to promote vascularization.
Developed a co-culture system using fibrin and collagen hydrogels.
Evaluated in vivo delivery of endothelial progenitor cells using collagen matrices.

Main Results:

Fibrin matrices with growth factors supported vascular growth and inflammatory cell invasion.
A fibrin-collagen matrix model successfully replicated cornea-sclera structures with innervation and vasculature.
Collagen matrices effectively delivered endothelial progenitor cells to ischemic tissue in vivo, promoting vascular integration.

Conclusions:

Developed functional tissue engineered matrices for supporting multiple cell types and vascularization.
Demonstrated potential for in vitro models of complex tissues like the cornea-sclera.
Highlighted the utility of these matrices for cell transplantation and in vitro studies.
