Clinical Applications of Epidermal Stem Cells01:19

Clinical Applications of Epidermal Stem Cells

3.1K
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...

Area of Science:

  • Plastic Surgery
  • Reconstructive Surgery

Background:

  • Scalp reconstruction presents unique challenges due to inelasticity, stiffness, and hair follicles.
  • Tissue expansion is a preferred method for aesthetic scalp reconstruction with low donor-site morbidity.

Observation:

  • Scarred scalp reconstruction is limited by reduced tissue availability for expander insertion.
  • Two cases of scarred scalp reconstruction using rectangular tissue expanders are presented.

Findings:

  • Rectangular expanders, inflated to 195 mL and 400 mL over 2-3 months, facilitated subgaleal elevation of fasciocutaneous flaps.
  • Successful reconstruction of chronic defects (4x3 cm) and large scar tissue areas (11x7.5 cm) was achieved.
  • Expanded tissue provided good color, texture, and hair-bearing coverage without complications.

Implications:

  • Rectangular expanders offer superior tissue yield compared to round or crescent shapes.
  • Their defined base allows easy insertion in confined spaces, ideal for scarred scalp reconstruction.
  • Rectangular expanders are recommended for challenging scarred scalp reconstructions.
