Insights

Pericytes (PCs), crucial for blood vessel health, are also stem cells in fat tissue. Understanding PC markers aids in targeting metabolic and bone diseases.

Area of Science:

  • Cell Biology
  • Vascular Biology
  • Adipose Tissue Biology

Background:

  • Pericytes (PCs) are perivascular cells integral to microvessel stability and function.
  • PCs possess multi-potent stem/progenitor cell properties within various adipose tissues.
  • The heterogeneity and precise identification of PCs present significant research challenges.

Purpose of the Study:

  • To review common pericyte markers used in lineage-tracing studies.
  • To highlight the role of pericytes in adipogenesis across different adipose depots.
  • To discuss pericyte functions under various metabolic conditions.

Main Methods:

  • Literature review of pericyte markers.
  • Analysis of lineage-tracing studies involving pericytes.
  • Synthesis of data on pericyte contribution to adipogenesis and function.

Main Results:

  • Multiple markers are utilized for pericyte identification and lineage tracing.
  • Pericytes contribute to the development and function of white, brown, and beige adipose tissues.
  • Pericyte behavior and function are modulated by metabolic state.

Conclusions:

  • A deeper understanding of pericyte heterogeneity is essential for therapeutic applications.
  • Targeting pericytes may offer novel strategies for treating metabolic and bone-related disorders.
  • Further research into pericyte markers and functions can unlock their therapeutic potential.

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...

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...

Phosphoinositides and PIPs01:42

Phosphoinositides and PIPs

Phosphoinositides are a group of phospholipids containing a glycerol backbone with two fatty acid chains and a phosphate attached to a myoinositol sugar ring. The inositol head group extends into the cytoplasm, where it is modified by adding phosphate groups to form phosphatidylinositol phosphates or PIPs.
Different phosphoinositides are synthesized and recruited on the cytosolic face of the plasma membrane. The localization of specific phosphoinositides concentrated in separate membrane...

Cholesterol: Significance and Regulation01:29

Cholesterol: Significance and Regulation

Although not a source of energy, cholesterol plays a significant role as a foundational structure for bile salts, steroid hormones, and vitamin D, as well as being a crucial component of plasma membranes. Approximately 15% of blood cholesterol is derived from our diet, with the remainder synthesized from acetyl CoA by the liver and intestines. Cholesterol is eliminated from the body through its conversion into bile salts, which are eventually discarded in the feces.
Considering cholesterol and...
