FIG. 5.

TDIs in testes of mice irradiated with 10.5 Gy (A) from Exp. 3 or 13.5 Gy (B, endogenous and C, transplanted) from Exp. 4, with and without hormonal suppression. Furthermore, in the transplanted testes, the TDI of the endogenous cells and donor cells were scored separately. N = 10 for 46-week time point group and 5 for all other time point groups for both irradiation doses. The statistical analysis of 46-week TDI data in panel (B) was conducted by a nonparametric method because the data are not normally distributed. “a” and “c”, p < 0.05 versus values in the sham group and transplant-only group, respectively.
