[Current status of tissue engineering for therapeutic use]

Area of Science:

• Biomedical Engineering
• Regenerative Medicine
• Transplantation Science

Context:

• Organ transplantation faces significant clinical hurdles including donor organ shortages, high costs, infection risks, and the need for lifelong immunosuppression, especially impacting pediatric recipients.
• These limitations hinder the widespread application and long-term success of current transplantation strategies.

Purpose:

• To review recent progress in tissue engineering as a potential alternative to organ transplantation.
• To discuss the remaining challenges in developing viable tissue-engineered solutions.
• To present a practical methodology for tissue engineering applications in cardiovascular surgery.

Summary:

• Tissue engineering research has advanced significantly, showing potential to overcome major limitations of organ transplantation.
• Key challenges remain in scaling up tissue engineering solutions and ensuring their long-term efficacy and safety.
• A specific practical method for cardiovascular tissue engineering is detailed, offering a tangible approach.

Impact:

• Tissue engineering could revolutionize treatment for organ failure, reducing reliance on donor organs and mitigating immunosuppression complications.
• Successful implementation of tissue engineering, particularly in cardiovascular surgery, may improve patient outcomes and reduce healthcare burdens.
• This work provides a roadmap for future research and clinical translation in regenerative medicine for organ replacement.
