Area of Science:

  • Regenerative Medicine
  • Biomaterials Science
  • Transplantation Surgery

Background:

  • Free tissue transfers, including whole organs and tissues, have advanced significantly with microvascular anastomosis.
  • Limited organ availability for transplantation causes patient suffering and psychological distress due to long waiting periods.
  • Tissue engineering emerges as a transformative field addressing organ scarcity in transplantation.

Purpose of the Study:

  • To explore the application of tissue engineering in enhancing free tissue transfers.
  • To investigate the use of biodegradable polymers as scaffolds for cell delivery and tissue regeneration.
  • To demonstrate the potential of tissue-engineered constructs for reconstructing various tissues and organs.

Main Methods:

  • Culturing small biopsy specimens into large cell populations.
