Phases of Wound Repair01:28

Phases of Wound Repair

9.3K
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...

Overview of Regeneration and Repair01:19

Overview of Regeneration and Repair

5.7K
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.

Inflammatory Response II: Inflammatory Exudate and Tissue Repair01:24

Inflammatory Response II: Inflammatory Exudate and Tissue Repair

8.8K
The immune system's inflammatory response destroys the invading pathogen, permitting the tissue to heal. The changes during the cellular and vascular stages allow exudate formation at the site of inflammation. The inflammatory exudate released from the wound has high protein content and a specific gravity above 1.020.
The typical wound exudate is odorless, transparent, straw-colored, thin, and watery. Exudate, however, can differ depending on the state of wound healing. Likewise, the...

Clinical Applications of Epidermal Stem Cells01:19

Clinical Applications of Epidermal Stem Cells

3.4K
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...

Renewal of Skin Epidermal Stem Cells01:12

Renewal of Skin Epidermal Stem Cells

3.2K
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...

Area of Science:

  • Regenerative Medicine
  • Tissue Engineering
  • Surgical Science

Background:

  • Wound healing is a complex biological process vital for tissue repair.
  • Understanding the nuances of healing across different tissues (skin, bone, cartilage, tendon) is crucial for effective treatment.
  • Factors influencing healing can significantly impact patient recovery and surgical success.

Purpose of the Study:

  • To elucidate the fundamental physiologic events in normal wound healing.
  • To differentiate the healing processes among various connective tissues.
  • To identify key factors that impede or delay wound healing and outline optimal wound closure strategies.

Main Methods:

  • Review of current scientific literature on wound healing physiology.
  • Comparative analysis of healing mechanisms in skin, bone, cartilage, and tendon.
  • Identification of clinical factors affecting wound healing outcomes.

Main Results:

  • Detailed description of the stages of normal wound healing.
  • Highlighting distinct healing capacities and timelines for different tissue types.
  • Enumeration of systemic and local factors that compromise wound repair.

Conclusions:

  • A thorough understanding of wound healing physiology and pathophysiology is essential for plastic surgeons to enhance postoperative results.
  • Knowledge of potential impediments allows for proactive management, potentially reducing the need for further surgical intervention.
  • This review serves as a foundational resource for evidence-based clinical recommendations in wound management, with a second part to follow.
