Area of Science:

  • Transplantation immunology
  • Organ preservation science
  • Regenerative medicine

Background:

  • Organ transplantation is a successful but supply-limited medical procedure.
  • Ischemia/reperfusion (I/R) injury is a complex challenge in transplantation.
  • Traditional static cold storage has limitations in preventing I/R injury and assessing organ viability.

Purpose of the Study:

  • To review current and emerging strategies for enhanced organ preservation.
  • To evaluate the potential of novel techniques in mitigating ischemia/reperfusion injury.
  • To explore the future role of normothermic preservation in organ transplantation.

Main Methods:

  • Review of existing literature on organ preservation techniques.
  • Analysis of donor preconditioning strategies targeting HO-1 and apoptosis.
  • Evaluation of viability assessment methods like microdialysis and bioimpedence.
  • Assessment of hypothermic and normothermic machine perfusion systems.

Main Results:

  • Donor preconditioning shows convergence on key pathways like HO-1 and apoptosis.
  • Microdialysis and bioimpedence offer potential for viability assessment during cold storage.
  • Hypothermic machine perfusion is being investigated for non-heart-beating donor kidneys.
  • Normothermic preservation demonstrates experimental benefits over cold storage, including reduced I/R injury and organ resuscitation.

Conclusions:

  • Enhanced organ preservation is crucial due to increasing use of marginal organs and I/R injury.
  • Normothermic preservation presents significant advantages over cold storage and is likely to gain importance.
  • Further clinical trials are needed to validate the efficacy of advanced preservation techniques, particularly normothermic preservation.
