Effect of epicatechin on viability of the HaCaT cells after treatment with radiation.

<p>The HaCaT cells were exposed to a single dose of radiation (20 Gy), various concentrations of EC (0–200 µM) or radiation plus EC. At 5 days interval after irradiation, cell viability was measured by MTT assay. The data represent the mean ± SD of three independent experiments. * <i>p</i><0.05, ** <i>p</i><0.01, *** <i>p</i><0.001, compared to radiation alone.
