From: Impact of aging on gene expression response to x-ray irradiation using mouse blood

Total white blood cell count (WBC) and percentages of different blood cell types in young and old mice after 1 day of radiation exposure (4 Gy). (a) total WBC counts, (b) lymphocytes (%), (c) neutrophils (%), (d) monocytes (%), (e) platelets counts. Data represent the mean ± S.E.M. (n = 3). P values were calculated using the unpaired Student’s t-test. YUI young unirradiated, YIR young irradiated, OUI old unirradiated, OIR old irradiated.
