Relationship between radiobiological hypoxia and direct estimates of tumour oxygenation in a mouse tumour model

Radiother Oncol. 1993 Jul;28(1):69-71. doi: 10.1016/0167-8140(93)90188-e.


CDF1 mice were allowed to breathe either oxygen, carbogen or different concentrations of carbon monoxide gas. These treatments significantly altered the percentage of clonogenic hypoxic cells in a C3H mouse mammary carcinoma and these changes were found to correlate with direct measurements of tumour oxygenation obtained using an Eppendorf pO2 electrode.
