Organ transplantation has revolutionized modern medicine, saving countless lives and improving the quality of life for many individuals suffering from organ failure. However, the success of organ transplantation largely depends on the availability of viable and functional organs. Organ preservation techniques play an important role in ensuring the organs remain viable during the transplantation process. Over the years, advances in medical research have led to the development of various preservation methods, each aimed at enhancing organ viability, function and the overall success of transplantation procedures. It is the process of maintaining the vitality and function of organs that have been removed from the donor's body until they are transplanted into the recipient. This crucial step is necessary to minimize ischemic injury, which occurs when organs suffer from reduced blood flow during the transplantation process. The longer the organ remains without a steady supply of oxygen and nutrients, the higher the risk of irreversible damage [1-3].
Hypothermic preservation, commonly known as cold storage is one of the oldest and most widely used methods of preserving organs. This technique involves cooling the organ to temperatures near 0°C, reducing its metabolic rate and slowing down cellular degradation. Cold storage is relatively simple, cost-effective, and suitable for organs like kidneys, liver, and pancreas. However, it is not ideal for all organs, as prolonged cold ischemia can still lead to tissue damage and decreased organ quality. Hypothermic machine perfusion is an advanced preservation technique that involves circulating a cold, oxygenated solution through the blood vessels of the donor organ while maintaining a low temperature.
This method allows for continuous oxygenation and nutrient delivery to the organ, reducing the risk of ischemic injury and improving organ quality. Hypothermic machine perfusion is particularly beneficial for marginal organs, such as those from older donors or those with preexisting medical conditions. Normothermic machine perfusion is an emerging preservation technique that keeps the organ at body temperature and provides a continuous supply of oxygen and nutrients. Unlike cold storage which merely slows down cellular processes, normothermic machine perfusion keeps the organ functioning at near-physiological conditions, allowing assessment and even treatment of potential issues before transplantation. This method has shown promising results for preserving organs like the liver, improving their overall quality and reducing post-transplant complications.
Cryopreservation involves freezing organs at very low temperatures, typically below -130°C, to preserve them for an extended period. The organs are stored in specialized cryoprotectant solutions to prevent ice crystal formation and cellular damage during freezing and thawing. While cryopreservation has great potential for preserving complex tissues and organs like the heart, lungs, and even whole limbs, current methods face challenges due to ice-induced cellular damage and cryoprotectant toxicity. Research in this area is ongoing, aiming to overcome these obstacles and improve the viability of cryopreserved organs [4-6].
Even with improved preservation methods, some level of ischemic injury is inevitable. Reducing this injury remains a primary focus of research. Organ shortage remains a important issue in transplantation. Maximizing the preservation period is crucial to ensure that organs reach their intended recipients without compromising viability [7,8]. Continued research and development of innovative preservation technologies, such as nanotechnology and tissue engineering, hold the promise of further improving organ preservation and increasing transplant success rates. By advancing organ preservation methods, we can improve the chances of successful transplantation and ultimately save more lives, cementing the incredible impact of organ transplantation on modern medicine [9,10].
