Insights

Androgens, like testosterone, appear to inhibit wound healing and increase inflammation. Blocking the androgen receptor or castration accelerates healing and reduces inflammation in male mice.

Area of Science:

  • Dermatology
  • Endocrinology
  • Immunology

Background:

  • Androgen receptor expression is noted in cells crucial for wound healing, including inflammatory cells, keratinocytes, and fibroblasts.
  • The precise role of androgens in regulating inflammatory and repair processes during cutaneous wound healing remains incompletely understood.

Purpose of the Study:

  • To review and synthesize current scientific understanding of how androgens influence tissue repair processes.
  • To elucidate the regulatory mechanisms by which androgens impact wound healing and inflammation.

Main Methods:

  • Review of existing literature on androgens, androgen receptors, and their involvement in cutaneous wound healing.
  • Analysis of studies investigating the effects of castration and androgen receptor antagonists on wound repair and inflammation.

Main Results:

  • Endogenous testosterone appears to inhibit the cutaneous wound healing process.
  • Androgen activity is associated with an increased inflammatory response during wound healing.
  • Castration in male mice or administration of an androgen receptor antagonist (flutamide) accelerates wound healing and attenuates inflammation.

Conclusions:

  • Androgens, particularly testosterone, play an inhibitory role in cutaneous wound healing.
  • Modulation of androgen signaling pathways may represent a therapeutic target for enhancing wound repair and managing inflammation.

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,...

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 EpiSCs...
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.

Phases of Wound Repair01:28

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...
Inflammatory Response01:28

Inflammatory Response

An inflammatory response is a localized, nonspecific immune reaction that occurs when a tissue is injured. It is characterized by redness, swelling, heat, and pain, which are commonly called the cardinal signs and symptoms of inflammation. Inflammation can sometimes result in a loss of function.
Inflammation can be triggered by various stimuli, such as impact, abrasion, chemical irritation, infections, and extreme hot or cold temperatures. These can damage cells and connective tissue fibers,...

Healing I: Introduction

Healing is the physiological process by which the body restores the integrity and function of damaged tissues following injury. It involves a coordinated interplay of cellular proliferation, extracellular matrix remodeling, and growth factor signaling. The extent and nature of the tissue damage determine whether healing occurs by resolution, regeneration, or replacement.ResolutionResolution represents the most complete form of healing, occurring when the injury is minimal and tissue...
