Ethical aspects of tissue engineering: a review

Area of Science:

• Biomedical Engineering
• Medical Ethics

Background:

• Tissue engineering (TE) is an emerging medical technology with significant potential.
• Like all novel technologies, TE presents unique ethical challenges.
• Proactive identification of ethical issues is crucial for responsible scientific advancement and societal trust.

Purpose of the Study:

• To systematically review and categorize documented ethical issues in tissue engineering.
• To identify the most debated ethical topics within the existing scientific literature.
• To explore and discuss ethical considerations that are currently underrepresented or unaddressed.

Main Methods:

• Comprehensive literature search of scientific databases.
• Systematic review and thematic analysis of relevant publications.
• Identification and categorization of ethical issues discussed in relation to tissue engineering.

Main Results:

• The use of human embryonic stem cells and therapeutic cloning are the most frequently discussed ethical concerns.
• Ethical issues span various stages of tissue engineering development.
• Several ethical aspects are identified that have not yet been extensively addressed in the literature.

Conclusions:

• A significant body of literature addresses key ethical challenges in tissue engineering.
• Further research and discussion are needed to explore emerging and underexplored ethical considerations.
• Addressing these ethical dimensions proactively will guide responsible innovation in tissue engineering.
