Spheroids Cultured Under Hypoxia
|Spheroids Cultured Under Hypoxia
This image shows a cultured tumor spheroid in a state of hypoxia under 1 percent oxygen. Hypoxic areas of the spheroid are marked in green, with nuclear DIPA co-staining (blue). As tumors grow, they outpace the surrounding blood vessels' ability to provide enough oxygen, a state known as hypoxia. Rather than killing the tumor, however, hypoxia somehow triggers changes in cancer cell metabolism that allow for the tumor's continuous growth and spread into nearby tissues. Understanding more about hypoxia in cancer cells may help researchers find better ways of managing the disease.
