Area of Science:

  • Regenerative Medicine
  • Gene Therapy
  • Tissue Engineering

Background:

  • Skin's accessibility makes it ideal for gene therapy and in vivo protein delivery.
  • Genetically modified epidermal cells can create skin substitutes acting as bioreactors.
  • Current methods often yield temporary transgene expression due to cell differentiation and loss.

Purpose of the Study:

  • To review advances in epidermal stem cell isolation and gene transfer.
  • To discuss the engineering of skin substitutes for therapeutic protein delivery.
  • To explore applications in treating genetic diseases, chronic wounds, and systemic disorders.

Main Methods:

  • Review of recent literature on epidermal stem cell research.
  • Analysis of gene transfer technologies for stable genetic modification.
