Insights

Fibroblast growth factors (FGFs) and their receptors (FGFRs) are crucial for stem cell self-renewal and tissue repair. This review explores their role in combating aging and promoting regeneration.

Area of Science:

  • Biogerontology
  • Stem Cell Biology
  • Molecular Medicine

Background:

  • Aging diminishes tissue function and regenerative capacity, linked to cellular senescence and reduced somatic stem cell activity.
  • Stem cell therapies offer promising avenues for mitigating aging effects and enhancing tissue repair.
  • Understanding stem cell self-renewal mechanisms is key to unlocking these therapeutic potentials.

Purpose of the Study:

  • To review the established roles of fibroblast growth factors (FGFs) and their receptors (FGFRs) in stem cell biology.
  • To elucidate the involvement of FGF/FGFR signaling in cellular senescence and the aging process.
  • To highlight the therapeutic potential of FGFs and FGFRs in regenerative medicine and anti-aging strategies.

Main Methods:

  • Literature review of studies on FGFs, FGFRs, stem cell self-renewal, and aging.
  • Analysis of molecular mechanisms underlying FGF signaling in somatic stem cells.
  • Synthesis of evidence linking FGF/FGFR pathways to cellular senescence and age-related tissue decline.

Main Results:

  • FGFs and FGFRs are identified as critical regulators of stem cell self-renewal across various tissues.
  • FGF signaling actively promotes self-renewing proliferation and inhibits cellular senescence.
  • Evidence suggests FGFs play a significant role in maintaining tissue homeostasis and repair throughout the aging process.

Conclusions:

  • FGFs and FGFRs are pivotal in maintaining stem cell function and combating age-related decline.
  • Targeting FGF signaling pathways presents a promising therapeutic strategy for regenerative medicine.
  • Further research into FGFs and FGFRs could lead to novel interventions for aging and tissue regeneration.

Role Of Notch Signalling In Intestinal Stem Cell Renewal01:12

Role Of Notch Signalling In Intestinal Stem Cell Renewal

Notch signaling was first discovered in Drosophila melanogaster, where it is involved in cell lineage differentiation. Notch signaling regulates the maintenance and differentiation of intestinal stem cells or ISCs by controlling the expression of atonal homolog 1 or Atoh1. Atoh1 directs cells to differentiate into secretory cells.
Direct cell-to-cell contact is needed for the activation of Notch signaling. The signal is initiated when a notch ligand binds to a receptor on an adjacent cell, also...
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...
Multipotency of Hematopoietic Stem Cells01:19

Multipotency of Hematopoietic Stem Cells

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...
Replicative Cell Senescence02:15

Replicative Cell Senescence

Replicative cell senescence is a property of cells that allows them to divide a finite number of times throughout the organism's lifespan while preventing excessive proliferation. Replicative senescence is associated with the gradual loss of the telomere — short, repetitive DNA sequences found at the end of the chromosomes. Telomeres are bound by a group of proteins to form a protective cap on the ends of chromosomes. Embryonic stem cells express telomerase — an enzyme that adds the telomeric...

Renewal of Skin Epidermal Stem Cells01:12

Renewal of Skin Epidermal Stem Cells

The skin is divided into epidermis, dermis, and hypodermis, the skin's outermost, middle, and inner layers. The human epidermal layer regularly undergoes renewal, where old, dead cells are replaced by new cells. Epidermal stem cells or EpiSCs divide and differentiate to restore the lost cells. For the renewal process, some EpiSCs continuously self-renew. In contrast, few others differentiate into transit-amplifying cells, which later form prickle or spinous cells, followed by granular cells,...
