Figure 1From: Identification of a stem-like cell population by exposing metastatic breast cancer cell lines to repetitive cycles of hypoxia and reoxygenationAn illustration of the hypoxia and reoxygenation regimen. Conditions for hypoxia/reoxygenation cycles were optimized using two human metastatic breast cancer cell lines (MDA-MB 231 and BCM2). The viability of non-adherent cells is listed after each hypoxic cycle. FBS, fetal bovine serum.Back to article page
