In the number of lymphoid cells (hCD332) than in the number

In the KDM5A-IN-1 chemical information number of lymphoid cells (hCD332) than in the number of myeloid cells (hCD33+) in the bone marrow and peripheral blood (Fig. 4B). Initially, the spleen and thymus contained only a few myeloid cells (less than 4 of total leukocytes). The percentages of individual types of T cells in the thymus, as identified using differentiation markers, are shown in Figure 4C. The relative abundance of hCD4+hCD8+ cells was affected by benzene administration to a greater extent than the other 3 T cell populations (hCD4+hCD8+ cells constituted 70.1, 59.8, 52.1, 2.6, and 0.6 11967625 of T cells in the thymus of Hu-NOG mice after 0, 10, 30, 100, and 300 mg/kgb.w. benzene administration, respectively).Comparison of Benzene buy I-BRD9 Toxicity in Hu-NOG and Mo-NOG MiceIn this study, NOG mice (CD45.1) with different strain-derived mouse hematopoietic lineages were established by transplantingIn Vivo Tool for Assessing Hematotoxicity in HumanFigure 4.

In Mo-NOG mice, C56BL/6 mouse cells succeeded in reconstituting the hematopoietic cell population (Fig. 3B). After benzene administration under the same conditions as for Hu-NOG mice, the degree of benzene-induced hematotoxicity suffered by MoNOG mice was compared with that of Hu-NOG mice. Humans are known to be more susceptible to the toxic effects of benzene than mice [20,21]. The cell number ratio of donor cell-derived human or mouse leukocytes in Hu-NOG and Mo-NOG mice after benzene administration, based on the number of leukocytes in untreated mice, is shown in Figure 5A. This comparison indicated that fewer human leukocytes were present in all target tissues of Hu-NOG mice in comparison with the number of leukocytes present in Mo-NOG mice. The difference in leukocyte number ratios between these mouse groups was large, particularly in the spleen and thymus, where lymphoid cells represented most of the leukocytes. In the bone marrow, the differences tended to vary depending on the amount of benzene administered. In contrast, differences in the peripheral blood followed the reverse tendency. Thus, the difference in cell number ratios was larger in.In the number of lymphoid cells (hCD332) than in the number of myeloid cells (hCD33+) in the bone marrow and peripheral blood (Fig. 4B).
