[Status and challenges of tissue-engineered skin]

Area of Science:

• Biomaterials Science
• Regenerative Medicine
• Tissue Engineering

Background:

• Autologous split-thickness skin grafting is a standard procedure for skin defect repair.
• Limitations include donor site morbidity and insufficient skin availability.
• Tissue-engineered skin aims to overcome these limitations for permanent defect replacement.

Purpose of the Study:

• To review the current status of various tissue-engineered skin products.
• To discuss the opportunities and challenges in developing advanced tissue-engineered skin.

Main Methods:

• Literature review of existing tissue-engineered skin technologies.
• Analysis of market-available products and their clinical applications.
• Discussion of future research directions and developmental hurdles.

Main Results:

• Several tissue-engineered skin products are available for clinical use.
• Despite progress, achieving fully regenerative skin repair is still an unmet goal.
• Significant challenges persist in the development of next-generation tissue-engineered skin.

Conclusions:

• Tissue-engineered skin represents a significant advancement over traditional grafting methods.
• Further research and development are crucial to overcome current limitations.
• The field holds promise for improved treatment of extensive skin defects.
