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...

Phases of Wound Repair01:28

Phases of Wound Repair

9.6K
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 Repair

5.8K
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.
Regeneration
All animals have varying degrees of...

Purpose of the Study:

  • To synthesize literature on laser scar management.
  • To provide guidelines for cutaneous scar treatment using laser technology.

Main Methods:

  • Extensive medical literature review on scar treatment.
  • Assessment of treatments based on scar features, location, and skin phototype.
  • Development of recommendations and algorithms.

Main Results:

  • Combination therapy (laser and non-laser) is safe and effective for scar revision.
  • Various laser modalities can be employed for scar treatment.

Conclusions:

  • Understanding available therapies allows for improved scar cosmesis.
  • This review covers current and emerging laser therapies for scar revision.
