'''21st Century Medicine''' ('''21CM''') is an American for-profit [[Cryobiology|cryobiological]] research company. It has as its primary focus the development of [[Perfusion|perfusates]] and protocols for viable long-term [[cryopreservation]] of mammalian and human organs, tissues, and cells through the use of [[vitrification]]. With its offices and laboratories in Fontana, California, 21CM was founded in 1993.<ref>[https://www.21cm.com/our_company.html Our Company]. 21cm.com</ref><ref>[https://www.crunchbase.com/organization/21st-century-medicine 21st Century Medicine]. crunchbase.com</ref>

21CM developed [[cryoprotectant]]s [[B1C]], [[B2C]], and [[M22]] that the [[Alcor Life Extension Foundation]] has used in vitrification of [[cryonics]] patients.<ref name="Human p. 554">[https://www.alcor.org/docs/cryopreservation-procedures-book.pdf Human Cryopreservation Procedures] (page 554)</ref> People employed at 21CM include or included [[Greg Fahy]], [[Aurelia Song]], and [[Brian Wowk]].

== History ==
In 2004, 21CM received a $900,000 grant from the U.S. National Institutes of Health (NIH) to study a preservation solution developed by the University of Rochester in New York for extending simple cold storage time of human hearts removed for [[Organ transplantation|transplant]].<ref>[https://web.archive.org/web/20160305034109/https://www.thefreelibrary.com/21st+Century+Medicine+Receives+NIH+Grant+to+Pursue+Heart+Preservation.-a0122727566 21st Century Medicine Receives NIH Grant to Pursue Heart Preservation.].

At the July 2005 annual conference of the [[Society for Cryobiology]], 21CM announced the [[Cryopreservation of rabbit kidneys|vitrification of a rabbit kidney]] to −135&nbsp;°C with their vitrification mixture. The kidney was successfully transplanted upon rewarming to a rabbit, the rabbit being euthanized on the 48th day for histological follow-up.<ref>[https://web.archive.org/web/20060830143259/http://www.me.umn.edu/events/cryo2005/program.html Plenary Session: Fundamentals of Biopreservation].
