From: Long-term exposure to hypoxia inhibits tumor progression of lung cancer in rats and mice
Experimental Protocols. (A) Animals in normoxia for 14 days after tumor cell injection. (B) Animals in hypoxia for 14 days after tumor cell injection. (C) Animals in normoxia for 4 days after tumor cell injection and then in hypoxia for 10 days. (D) Animals in normoxia for 7 days after tumor cell injection and then in hypoxia for 7 days. (E) Followed in normoxia for 4 days after tumor cell injection, animals were placed in hypoxia for 10 days and then returned to normixa for another 7 days.
