Radiosensitivity of head and neck cancer cells in vitro. A 96-well plate clonogenic cell assay for squamous cell carcinoma.

Radiation sensitivity was determined for nine University of Michigan squamous cell carcinoma (UM-SCC) cell lines, MCF-7 and HeLa, using a 96-well plate clonogenic assay. Plating efficiencies (PE) of the UM-SCC cell lines were between 0.16 and 0.
