Figure 4From: Administration of ON 01210.Na after exposure to ionizing radiation protects bone marrow cells by attenuating DNA damage responseTUNEL staining of bone marrow and spleen sections at 7 d post-radiation. A) Photomicrograph showing TUNEL staining of bone marrow sections at 20× magnification. B) Quantification of TUNEL positive cells in bone marrow sections. *p < 0.01 compared to radiation+vehicle (R+V). C) Photomicrograph showing TUNEL staining of spleen sections at 20× magnification. D) Quantification of TUNEL positive cells in spleen sections. *p < 0.05 compared to radiation+vehicle. Control: no radiation, ON 01210.Na or vehicle; R: 5 Gy radiation; R+V: 5 Gy radiation+vehicle; R+D: 5 Gy radiation+drug (ON 01210.Na).Back to article page
