Bryden University was a private university in Washington, D.C..
Bryden funded experimental research on treatments for prion diseases that involved the use of stem cells. After Jack Bauer got infected with Starkwood's chemical weapon, Dr. Sunny Macer mentioned Bryden's experimental work. She told Jack that the treatment involved the use of stem cells from the blood of a close relative to cure the infection. When she mentioned Jack's daughter, Kim Bauer, as a possible donor, he quickly rejected it, not wanting to get her involved. ("Day 7: 12:00am-1:00am")
