Figure Lengend Snippet: Cyclophosphamide significantly decreased the testicular weight and seminiferous tubule normal histology, VASA cells GFR-α-1, α-6-Integrin, CD9, and C-KIT cells counts in the tubules of immature mice: cyclophosphamide (CP) was intraperitoneally injected (i.p; 100 mg/kg in 100 uL; see methodology section) (CP) or PBS (control, CT; 100 uL). One to 5 weeks after the last injection, mice were sacrificed, and testes were removed, weighed, and fixed in Bouin’s solution for histological evaluation. Changes in the testes weight following CP treatment (CP) compared to control (Control) is presented ( A ). The histology of the seminiferous tubules was examined by hematoxylin-eosin staining ( B ) and a summary of seminiferous tubule damage after 1–5 weeks post CP (CP) treatment compared to the CT is presented ( C ). Ten days post-treatment, the histology of the seminiferous tubules was evaluated by H&E staining ( D ), testes were weighed ( E ), and the total number of cells isolated from the seminiferous tubules were counted ( F ). The presence of VASA-, GFR-α-1-, α-6-Integrin-, CD9-, and C-KIT-positive stained cells in the seminiferous tubules of CT and CP-treated immature mice ( G – K ) was examined by immunofluorescence staining (IF) using specific primary antibodies and Cy3 or Alexa-flour 488 with the relevant secondary antibodies (VASA, α-6-Integrin, CD9, and C-KIT red staining and GFR-α-1 green staining). DAPI (blue color) stained the nucleus of the cells. Arrows show the location of stained cells in the testicular tissues. As a negative control (NC), we stained the tissues only with the secondary antibodies (NC for α-6-Integrin, CD9 and C-KIT were similar and therefore, we present only NC for α-6-Integrin).
