Insights

Reactive oxygen species (ROS) play a dual role in wound healing. While low levels aid healing, excessive ROS prolong inflammation, hindering recovery. Antioxidant therapies targeting ROS show promise for chronic wound treatment.

Area of Science:

  • Biomedical Science
  • Wound Healing Research
  • Oxidative Stress Biology

Background:

  • Reactive oxygen species (ROS) are crucial mediators in biological processes, exhibiting a dual role in wound healing.
  • Slightly elevated ROS levels can inhibit microbial infection, promoting early wound healing stages.
  • Conversely, excessive ROS accumulation at wound sites exacerbates inflammation, impeding the healing cascade and leading to chronic wounds.

Purpose of the Study:

  • To comprehensively review the intricate relationship between ROS and the critical phases of wound healing.
  • To elucidate the molecular and biomolecular mechanisms underlying ROS-mediated effects on cellular homeostasis and inflammation during wound repair.
  • To explore the potential of exogenous antioxidant therapeutics in manipulating ROS levels for enhanced chronic wound healing.

Main Methods:

  • Literature review synthesizing current research on ROS in wound healing.
  • Analysis of molecular pathways affected by ROS during different healing phases.
  • Evaluation of antioxidant therapeutic strategies targeting ROS scavenging for wound management.

Main Results:

  • ROS exhibit a biphasic effect on wound healing, beneficial at low concentrations and detrimental at high concentrations.
  • Excessive ROS disrupt cellular homeostasis and prolong the inflammatory phase, delaying wound closure.
  • Understanding ROS modulation is key to developing effective antioxidant therapies for chronic wounds.

Conclusions:

  • Targeting ROS represents a promising therapeutic strategy for improving chronic wound healing outcomes.
  • Antioxidant therapies that scavenge excess ROS can restore cellular balance and promote timely wound resolution.
  • Further research into ROS-mediated mechanisms will refine the application of antioxidant therapeutics in regenerative medicine.

Phases 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.
Formation of Blood Clot
In case of deep injuries, trauma to blood vessels results in blood loss. In the meantime, phospholipids released from the ruptured endothelial cellular membrane are converted into arachidonic...

Clinical Applications of Epidermal Stem Cells

Epidermal stem cells (EpiSCs) are mainly located at the basal layer of the epidermis. These cells repair minor injuries of the skin and replace dead skin cells. However, EpiSCs’ cannot heal severe wounds such as major burns or those from diabetes or hereditary disorders. In such cases, culturing the epidermal stem cells from the patient is possible and has yielded successful treatment options, such as laboratory-grown skin grafts. These grafts are synthesized using a patient’s own...

Overview of Regeneration and Repair01:19

Overview of Regeneration and Repair

Regeneration and repair processes are critical in healing damages caused by injury, disease, and aging. In regeneration, the damaged tissue is entirely replaced with new growth that restores the original architecture and function. In contrast, tissue repair usually results in a fixed tissue architecture involving scar formation. Scars generally do not reestablish tissue function and may also exhibit structural abnormalities at the injury site.
