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.
On August 23, the Jinan Private Economic Development Bureau and China Economic Weekly jointly launched the theme publicity activity of "Central Media Look at Jinan - Entering Jinan's Private Economy" in Yinfeng Biotechnology Park.
Led by Anhui Medical University and participated by Yinfeng Cryogenic Medical Technology Co., Ltd., the "Engineering Research Center for Life Resources Conservation and Artificial Organs of the Ministry of Education" was officially accepted and awarded by the Ministry of Education. As one of the four major platforms for the transformation of the center's project, Yinfeng Cryogenic Co., Ltd. is responsible for the "development, promotion and application of cryogenic preservation technology of biological matrix materials".
On March 28, 2023, the kick-off meeting of the International Alliance for Life Extension Research was held in Jinan, Shandong. The "International Alliance for Life Extension Research" was initiated by Shandong Yinfeng Life Science Research Institute, and jointly established by 13 international scientific research institutions engaged in the field of cryogenic biomedicine from North America, Europe, Oceania, etc., and appeared at the conference through online and offline forms.
