A Genomic Study of DNA Alteration Events Caused by Ionizing Radiation in Human Embryonic Stem Cells via Next-Generation Sequencing

Figure 2

H14 human embryonic stem cell growth after exposure to ionizing radiation. (a) Microscopic images of representative colonies at 0, 24, and 96 hours after exposure to 0, 0.2, or 1 Gy of ionizing radiation. (b) Cell growth curves of H14 human embryonic stem cells irradiated with 0, 0.2, or 1.0 Gy. The area of all colonies was normalized to 1 at the 0-hour time point. Averages of the measurement of 20 colonies are presented; error bars represent standard deviation.
