Insights

Pigment epithelium-derived factor (PEDF) is a potent endogenous inhibitor of stem cell neovascularization. This review highlights PEDF

Area of Science:

  • Biochemistry
  • Molecular Biology
  • Ophthalmology

Background:

  • Pigment epithelium-derived factor (PEDF) is an endogenous protein with diverse biological activities.
  • PEDF is widely expressed in various human tissues, including the eyes, liver, heart, and adipose tissue.
  • It possesses antiangiogenic, antitumorigenic, antioxidant, anti-inflammatory, antithrombotic, neurotrophic, and neuroprotective properties.

Purpose of the Study:

  • To review the significance of PEDF as an endogenous antiangiogenic molecule.
  • To focus on PEDF's recently identified role in inhibiting stem/progenitor cell-associated neovascularization.
  • To explore PEDF as a potential therapeutic target for diseases involving neovascularization.

Main Methods:

  • Literature review of studies on Pigment epithelium-derived factor (PEDF).
  • Analysis of PEDF's biological activities and expression patterns.
  • Examination of PEDF's role in neovascularization and related diseases.

Main Results:

  • PEDF is identified as the most potent inhibitor of stem/progenitor cell-associated neovascularization.
  • PEDF plays a role in the pathogenesis of angiogenic eye disease, tumor growth, and cardiovascular disease.
  • Novel antiangiogenic agents are needed for treating various diseases.

Conclusions:

  • PEDF is a crucial endogenous antiangiogenic factor.
  • PEDF's inhibition of stem/progenitor cell neovascularization presents a promising therapeutic target.
  • Further research into PEDF could lead to novel treatments for angiogenic diseases.

Regulation of Angiogenesis and Blood Supply01:24

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...
Role of Hematopoietic Growth Factors01:28

Role of Hematopoietic Growth Factors

Hematopoietic growth factors are molecules that regulate the differentiation rate of hematopoietic stem cells (HSCs). Erythropoietin (EPO), primarily produced by the kidneys, plays a crucial role in erythrocyte production. When oxygen levels in the blood are low, EPO is released into the bloodstream, reaching the bone marrow, where it stimulates HSCs to differentiate and mature into erythrocytes, which are vital for oxygen transport.
Thrombopoietin (TPO), mainly released by the liver,...
Mechanism of Angiogenesis01:10

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 Hematopoietic Stem Cells

All blood and immune cells are produced from the multipotent hematopoietic stem cells (HSCs) by the process of hematopoiesis. However, they all have a limited life span. In addition, many are depleted in immune surveillance or combatting an injury or infection. This makes blood one of the most regenerative tissues. Hematopoiesis helps replenish these blood and immune cells, restoring the body's normal functioning. However, overproduction of blood and immune cells can make them cancerous or...

Role of Ephrin-Eph Signalling in Intestinal Stem Cell Renewal

Erythropoietin-producing hepatocellular carcinoma receptor (Eph) and its ligand, Eph receptor-interacting protein (Ephrin) were first discovered in the human carcinoma cell line, hence the name. Ephrin-Eph interaction guides cells to reach their appropriate location in adult tissues. They also play an essential role in the immune system by helping in immune cell migration, adhesion, and activation. Based on their structure and function, Eph is divided into two classes — EphA and EphB.
Stem Cell Niche01:26

Stem Cell Niche

The stem cell niche is the dynamic microenvironment where stem cells reside. Inside these niches, the cells may remain undifferentiated, undergo high self-renewal, or become lineage-specific progenitors. Stem cells coexist with other niche cells, such as stromal cells. They also interact closely with the ECM. Cell-cell and cell-matrix communication occur via adhesion molecules or soluble factors that signal the stem cells and determine their fate. Stromal cells also provide survival signals to...
