Fontana, California, February 10, United Press International reported - A scientific team called "21st Century Medicine" successfully froze a rabbit brain and restored it back at a research institution in California.
This feat recently earned the team the Small Mammal Brain Preservation Award from the Brain Preservation Foundation.
"This is a near-perfect achievement, which shows that it is feasible to preserve the complete structure of mammalian brain organs for a long time." Foundation officials wrote in a press release.
The research team took advantage of a newly invented technology called "aldehyde-stabilized freezing." The process went through: first injecting glutaraldehyde into the brain, then injecting 65% ethylene glycol to stabilize and protect the brain structure, and then freezing the rabbit brain to -211 degrees Fahrenheit.
The difficulty with cryopreservation is that it cannot fully protect and preserve the brain's synaptic circuits, those fragile and critical neural parts that enable memory and learning, and are also key to decoding a person's identity. But recent successes show that the freezing method can work.
"Every neuron and process appears to be intact in the brain," said Kenneth Hayworth, president of the Brain Preservation Foundation. "What's amazing is that when the brain was vitrified and became very strong, the brain I held in my hand was the same as the original body. This is different from previous cryonics."
The same research team used ASC (cryopreservation technology stabilized with acetaldehyde) on pig brains that are structurally larger and closer to the human brain, and are currently awaiting experimental results.
The team's success with rabbit brains is detailed in a new research paper published in Cryobiology.
Latest developments
Over the two days, the symposium was not only a collision of ideas but also seeds sown to advance social progress in life culture. The Shandong Yinfeng Life Science Public Welfare Foundation will continue to use technology as wings and culture as roots, collaborating with all sectors of society to enhance the quality of life for the Chinese people and build a human-centered life care system.
According to recent announcements by the Jinan Municipal Bureau of Science and Technology, 11 outstanding achievements from Jinan have been included in the 2025 "Shandong Outstanding Achievements Report" project. Among them is the globally first-of-its-kind ovarian tissue dual-activation technology developed by Shandong Silver Med Life Science Research Institute (Jinan).
Recently, Frigid Zone Medicine, an authoritative international journal in the field of cryomedicine, published an important review titled "Advances in the Detection Methods for Assessing the Viability of Cryopreserved Samples". Written by the team of Yinfeng Cryomedical Research Center, the article systematically reviews and analyzes various detection techniques currently used to evaluate the viability of cryopreserved cells, tissues, and organs. It also proposes key directions from the perspectives of methodological integration and future instrument development, offering crucial theoretical support and practical guidance for the long - term cryopreservation of complex tissues and organs.
Recently, the "Novel Technology for Ultra-Low Temperature Cryopreservation, Activation, and Transplantation of Human Ovarian Tissue," developed through a collaborative effort between Shandong Yinfeng Life Science Research Institute and Beijing University of Chinese Medicine Shenzhen Hospital, has been awarded the 2025 Shandong Refrigeration and Air Conditioning Science and Technology Award. This groundbreaking technology pioneers a new pathway for female fertility preservation, marking a significant leap in China’s interdisciplinary advancements in reproductive medicine and cryobiology.
On May 19, a delegation from the Chinese Training Workshop for Government Officials of Developing Countries visited the exhibition hall of Yinfeng Biological Group's Cryomedicine Research Center. Government officials from multiple countries gained in-depth insights into Yinfeng’s innovative achievements in cryobiomedicine, cell storage, genetic technology, and other fields. They engaged in discussions with the delegation on technology transfer and international cooperation, contributing to the building of a global community with a shared future for humanity.
