Summary
The brain's neurovasculature guides neural stem cell (NSC) behavior. Targeting this crosstalk offers therapeutic potential for aging-related cognitive decline and NSC dysfunction.
Area of Science:
- Neuroscience
- Developmental Biology
- Cell Biology
Background:
- Neural stem cells (NSCs) are crucial for brain repair and function.
- Quiescent NSCs in the adult brain can be activated by environmental cues.
- The neurovasculature forms a critical niche influencing NSC behavior.
Purpose of the Study:
- To explore the intricate crosstalk between the brain's neurovasculature and neural stem cells.
- To understand how this interaction influences NSC fate and function.
- To discuss therapeutic strategies targeting neurovasculature-NSC signaling for cognitive health.
Main Methods:
- Review of existing literature on neurovasculature-NSC interactions.
- Analysis of signaling pathways involved in niche regulation.
- Consideration of model organism studies, including Drosophila melanogaster.
Main Results:
- The neurovasculature actively instructs NSC quiescence, proliferation, self-renewal, and differentiation.
- Age-related neurovascular decline impairs the NSC niche, leading to dysfunction.
- Targeting neurovascular components holds promise for enhancing NSC activity.
Conclusions:
- Neurovasculature-NSC crosstalk is fundamental to maintaining brain plasticity and function.
- Therapeutic strategies focused on the neurovascular niche could reverse age-associated NSC decline.
- Understanding this interaction is key for developing novel regenerative therapies.

6.5K
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...

4.0K
The hematopoietic stem cells or HSCs are multipotent, meaning they can differentiate and give rise to all blood and immune cells. HSCs are maintained in the quiescent stage until an external stimulus initiates their differentiation. The multipotent HSCs exist as two heterogeneous populations, long-term repopulating cells (LTRC) and short-term repopulating cells (STRC). The two HSC populations have different surface markers or receptors and are classified based on quiescence and long-term...

4.3K
A hair follicle or HF is a small part of the skin that produces the hair shaft. Paul Gerson Unna was the first to observe a bulge in the human hair follicle's outer root sheath (ORS). The bulge is present between the sebaceous gland and the arrector pili muscle and is the niche for hair follicle stem cells (HFSCs). The bulge is also a niche for melanocyte stem cells, and their loss results in graying of hair. The HFSCs express Sox9 and Lhx2, which help them maintain stemness and prevent...

01:24Regulation of Angiogenesis and Blood Supply
3.8K
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...

01:15Neurogenesis and Regeneration of Nervous Tissue
1.9K
In the CNS, neurogenesis, the birth of new neurons from stem cells, is limited to the hippocampus in adults. In other regions of the brain and spinal cord, neurogenesis is almost non-existent due to inhibitory influences from neuroglia, especially oligodendrocytes, and the absence of growth-stimulating cues. The myelin produced by oligodendrocytes in the CNS inhibits neuronal regeneration. Furthermore, astrocytes proliferate rapidly after neuronal damage, forming scar tissue that physically...

01:10Mechanism of Angiogenesis
7.3K
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...
