Astaxanthin (ATX) attenuates total body irradiation (TBI)-induced multilineage differentiation disorders and maintains hematopoietic homeostasis. Mice were sham-irradiated as a control or irradiated with 4 Gy TBI after receiving DMSO or various concentrations of ATX in a manner similar to that illustrated in Fig. 1. a Bar graph showing the numbers of white blood cells (WBC). b Bar graph showing the percentage of neutrophilic granulocytes (NE%) and (c) lymphocytes (LY%). The percentage of T cells (d), B cells (e), and myeloid cells (f) in peripheral blood detected by flow cytometry. The data are presented as the mean ± SEM (N = 5). ^a P < 0.05 vs control; ^b P < 0.05 vs TBI
