Discovered that glycerin could be used as a cryoprotectant to preserve sperm at low temperatures
Glycerin, as the main ingredient of the world’s first cryoprotectant, enabled humans to achieve efficient cryopreservation of semen for the first time, laying a solid technical foundation for human sperm banks built around the world after the 1960s. Currently, nearly 2 million in vitro fertilization and 1 million artificial insemination cases are performed globally each year, curing nearly 80% of infertile patients worldwide and bringing patients the opportunity to welcome new life.

In 1967, the world’s first cryopreserved human
Dr. James Bedford, was preserved at the American Human Cryonics Society (Alcor).

It kicked off the research on cryopreservation and resuscitation of human tissues and organs. At present, there are only 4 institutions in the world that can independently implement human cryopreservation. Shandong Yinfeng Life Science Research Institute in our country is the only institution in Asia that can independently implement human cryopreservation, and completed the first case of human cryopreservation in China in 2017. Currently, 16 volunteers from all over the country have been preserved in our institute. Human preservation and resuscitation research is a future-oriented and challenging frontier life science research project through the joint research of interdisciplinary subjects such as cryobiology, cryomedicine, molecular biology, and clinical medicine.

In 1989, Professor Belzer of the University of Wisconsin, USA
Invented the UW cryopreservation solution
In 1989, Professor Belzer of the University of Wisconsin, USA
Invented the UW cryopreservation solution
The invention of the UW preservation solution greatly improved the quality and preservation time of cell and in vitro tissue and organ preservation, and derived tens of thousands of various deep cryoprotectants on this basis, effectively reducing the formation of nearly 70% of ice crystals in cells, tissues, and organs, and prolonging and improving the life and postoperative quality of life of nearly 130,000 organ transplant patients worldwide each year.

Since then, the prelude to the treatment of major hematological diseases with umbilical cord blood stem cells has been opened. At present, 7 cord blood banks in the country have a total of 2.62 million cord blood stored, and a total of more than 30,000 patients have been cured by application, accounting for 35% of the total number of applications worldwide. The application of cord blood stem cells has saved tens of thousands of patients whose lives are threatened by hematological diseases.

In 2016, Shandong Yinfeng Life Science Research Institute
Developed the world’s first high-precision low-temperature programmed cooling equipment
In 2016, Shandong Yinfeng Life Science Research Institute
Developed the world’s first high-precision low-temperature programmed cooling equipment
At present, this programmed cooling equipment is the largest in the world, with the widest temperature control range and highest precision. It fills the global technical gap of programmed cooling instruments from room temperature to -196℃ in a continuous curve and solves the demand for large-size cooling instruments for various types of large-volume tissues, organs and human body preservation. It is exported and circulated worldwide, and was exported to Australia in 2021, demonstrating China’s scientific and technological strength in the cryobiological domain.

In 2017, Shandong Yinfeng Life Science Research Institute
First time applied the minimally invasive dual-channel extracorporeal circulation perfusion technology to human cryopreservation surgery
The application of human minimally invasive dual-channel extracorporeal circulation perfusion surgery technology, compared to the traditional need for thoracotomy to perfuse the human body with cryoprotectant, reduces the formation of wounds and ensures that the cryoprotectant can quickly and fully reach all tissues of the body, laying a good technical foundation for future human tissue and organ resuscitation experiments.

In 2023, the world’s first vitrified preservation
Nanoheated and rewarmed rat kidney successfully transplanted
In 2023, the world’s first vitrified preservation
Nanoheated and rewarmed rat kidney successfully transplanted
The team of Professor John Bischof of the University of Minnesota (UMN) in the United States successfully transplanted a rat kidney with vitrification preservation and nano-heating rewarming for the first time. This study demonstrates that long-term organ cryopreservation followed by transplantation can be made possible through vitrification and nano-rewarming technologies. This technological breakthrough may fundamentally change the current state of the field of organ transplantation, making the use of organ banks for transplantation a reality, thereby increasing the utilization rate of transplanted organs.

In 2024，The team of Dayong Gao, former president of the International Society for Cryobiology
Developed the Single-mode Electromagnetic Resonance (SMER) warming technology, which can rapidly and uniformly warm samples
The former president of the International Society for Cryobiology and the team of Dayong Gao from the Center for Cryo-biomedical Engineering and Artificial Organs at the University of Washington have introduced a breakthrough in warming technology. They have developed the Single-mode Electromagnetic Resonance (SMER) warming technology, which can rapidly and uniformly warm samples. This is a dielectric heating method based on Maxwell's theory, which raises the temperature of non-conductive samples by placing them in a high-frequency electromagnetic field. It can achieve very rapid and uniform heating in a short period of time, to some extent addressing the problem of ice recrystallization when biological materials are reheated.
