Regenerative medicine applied to solid organ transplantation: where do we stand?

Area of Science:

• Regenerative Medicine
• Tissue Engineering
• Biotechnology

Background:

• Regenerative Medicine (RM) and Tissue Engineering (TE) aim to restore tissue and organ function.
• RM/TE offers potential solutions for organ shortages and lifelong immunosuppression by using patient-derived cells.
• Significant advancements have been made, benefiting the transplant community.

Purpose of the Study:

• To highlight the objectives and promise of RM/TE in tissue and organ regeneration.
• To identify key challenges hindering the clinical application of RM/TE.
• To underscore areas requiring further scientific investigation for successful implementation.

Main Methods:

• Review of current RM/TE advancements and their implications.
• Analysis of biological and engineering challenges in tissue regeneration.
• Identification of critical research areas for future development.

Main Results:

• RM/TE shows promise in regenerating tissues and organs, potentially eliminating the need for transplants and immunosuppression.
• Striking results have been achieved in the past decade.
• Major obstacles include understanding cell-matrix interactions, safe and scalable cell expansion, vascularized scaffold production, and cost-effectiveness.

Conclusions:

• Deeper understanding of cell biology and extracellular matrix interactions is crucial.
• Developing methods for indefinite and safe cell expansion is necessary.
• Optimizing vascularized scaffolds, assessing cell viability, and reducing costs are key research priorities for advancing RM/TE.
