Organ preservation has always been a challenge in the field of medical advancements, with cryogenic damage posing a significant barrier to effective organ transplantations and treatments. The formation of ice crystals during freezing can lead to irreversible damage to cellular structures, ultimately resulting in organ failure. This issue affects thousands of individuals worldwide who are in need of organ transplants, creating a shortage of viable organs and long waiting lists for patients in need.
A study conducted by Prof. Ido Braslavsky, Dr. Vera Sirotinskaya, and Dr. Liat Bahari from the Hebrew University, in collaboration with Dr. Victor Yashunsky from Ben Gurion University of the Negev and Dr. Maya Bar Dolev from Technion, has brought to light a promising solution to cryogenic damage. Published in the journal Langmuir, the study focused on the use of antifreeze proteins (AFPs) to mitigate the effects of cryogenic damage. By utilizing advanced technology and different types of AFPs, such as AFPIII from fish and TmAFP from larvae of flour beetles, the research team successfully delayed crystallization and influenced devitrification even at temperatures below -80 degrees Celsius.
Dr. Bar Dolev emphasized the importance of the research findings, stating that the inhibition of crystallization and crystal growth through antifreeze proteins holds immense promise for extending the viability of frozen organs and enabling previously impossible transplants. Prof. Braslavsky further highlighted the potential impact of this breakthrough, envisioning longer preservation periods, enhanced quality during transport, and innovative transplant procedures, including complex organ combinations like heart-lung transplants and uterine tissue transplants.
The implications of this research are profound, offering hope for improved organ availability, extended preservation windows, and ultimately, saving countless lives. As the field of tissue preservation embraces the potential of antifreeze proteins, the future of organ transplantation shines brighter than ever before. The advancement in organ preservation technology through the strategic use of AFPs has opened doors to a new era in tissue preservation and transplant procedures, marking a significant step forward in the field of medical advancements.
