摘要

A hypoxic/anoxic microenvironment has been proposed to exist within a vascular lesion due to intimal or medial cell proliferation in vascular diseases. Here, we examined whether hypoxia alters macrophage function by exposing murine macrophage-like RAW 264.7 (RAW) cells to hypoxia (2/100 O_2). When cells were exposed to hypoxia, a significant number of RAW cells underwent apoptosis. Addi- tionally, small subpopulations of RAW cells were resistant to hypoxia-induced apoptosis. Through repeated cycles of hyp- oxia exposure, hypoxia-induced apoptosis-resistant macro- phages (HARMs) were selected; HARM cells demonstrate >70/100 resistance to hypoxia-induced apoptosis, as compared with the parental RAW cells.
