Timeline of survival experiment. Mice were preconditioned for 1 wk to 1 of 3 conditions [chronic intermittent hypoxia (CIH), static hypoxia, and normoxia]. After preconditioning, mice were injected with either 5TGM1 cells or saline, followed by 4 wk more of exposure. Mice were then returned to normal housing, where they were observed daily for signs of paralysis. Paralyzed mice were euthanized, and tissues were collected for examination.
