Summary
Sonic hedgehog (Shh) signaling is crucial for wound repair. Disrupting Shh pathways significantly impairs healing, suggesting its role in postnatal tissue regeneration and recovery.
Area of Science:
- Developmental Biology
- Regenerative Medicine
- Wound Healing Research
Background:
- Hedgehog morphogens, including sonic hedgehog (Shh), are key regulators of embryonic development and tissue patterning.
- While Shh is implicated in postnatal tissue repair, conclusive evidence remains limited.
Purpose of the Study:
- To investigate the role of Shh signaling in postnatal wound repair.
- To determine the effects of Shh pathway inhibition on the wound healing process.
Main Methods:
- Utilized a murine-splinted excisional wound model in rodents.
- Administered cyclopamine, a specific inhibitor of the Shh signaling cascade.
- Assessed wound healing parameters including closure, epithelialization, granulation, vascularity, and proliferation.
Main Results:
- Disruption of Shh signaling profoundly impaired wound healing across all measured parameters.
- Key aspects of repair such as wound closure, epithelialization, granulation formation, vascularity, and cell proliferation were significantly reduced.
- Inhibition of Shh signaling led to a marked delay in the overall wound healing process.
Conclusions:
- Sonic hedgehog (Shh) signaling is essential for effective postnatal wound repair.
- These findings highlight the potential therapeutic role of modulating Shh signaling in conditions with impaired wound healing.
- Further research into Shh signaling in disregulated wound healing is warranted.

02:33Hedgehog Signaling Pathway
The Hedgehog gene (Hh) was first discovered due to its control of the growth of disorganized, hair-like bristles phenotype in Drosophila, much like hedgehog spines. Hh plays a crucial role in the development of organs and the maintenance of homeostasis in both invertebrates and vertebrates. However, while Drosophila has only one Hh protein, mammals have multiple functional Hedgehog proteins - Sonic (Shh), Desert (Dhh), and Indian Hedgehog (Ihh). All of these homologous proteins have adapted to...

01:12Role 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...

03:14Notch Signaling Pathway
The Notch signaling pathway is a major intracellular signaling pathway that is highly conserved over a broad spectrum of metazoan species. It stands unique from other intracellular signaling mechanisms in animals because notch protein itself acts as the receptor as well as the primary signaling molecule.
The Notch gene came into the limelight in 1914 after the discovery that its mutation in Drosophila melanogaster leads to a serrated (or "notched") wing margin phenotype. It was not until 1985...

01:28Phases of Wound Repair
Following injury, the integrity of the injured tissues must be reestablished. For example, in skin tissue, wound repair involves coordination among resident skin cells, blood mononuclear cells, extracellular matrix, growth factors, and cytokines to complete the healing cascade.
