Moreover, it is widely believed that the existence of ESE itself is doubtful. However, assuming that ESE has a positive therapeutic effect, we designed simple experimental systems that may be able to detect the putative ESE by a colony-formation assay using cultured human cells exposed to chemical compounds or ionizing radiations that have a lethal effect on cell growth. We report here the results of two pilot experiments using G418 as a lethal compound and X ray as ionizing radiation. Although an enhancement of colony formation by ESE was not detected in the G418 experiment, a slight increase in the number of colonies formed was observed in the X ray irradiation experiment, possibly caused by the putative ESE.
