Fig. 1. Flow cytometric analysis of Hoechst 33342 fluorescence. (A) C57BL/6 adult
murine testicular cells. (B) Definition of the five main subpopulations and
respective percentages of total testicular viable cells: 1 (1%), 2 (2.4%), 3
(8%), 4 (7%), 5 (70%). (C,D) Comparison with two infertile murine models:
W/Wv mutant (C) and cryptorchid C57BL/6 male (D). (E,F)
Identification of somatic interstitial cells: interstitial cell-enriched
fraction (E) compared with the fraction enriched in seminiferous tubules (F).
Vertical axis shows blue (Ho) fluorescence, horizontal axis red (Ho/PI)
fluorescence.
