Rescue of Infertility in KitlSl/KitlSl-d Mice by AAV9-Kitl Infection

(A) Macroscopic, histological, and lectin-histochemical appearance of KitlSl/KitlSl-d mouse testes after microinjection with AAV9-Kitl.

(B) Immunostaining of KitlSl/KitlSl-d mouse testes by CD4 and CD8 antibodies 1 week after microinjection of Adex1CAmKL or AAV9-Kitl into the seminiferous tubules.

(C and D) Offspring born after microinsemination using sperm generated after tubular (C) or interstitial (D) injection of AAV9-Kitl.

(E and F) Southern blot analysis of DNA samples using a Kitl cDNA probe. DNA samples were collected from representative offspring born after microinsemination using sperm generated after tubular (E) or interstitial (F) injection of Kitl-expressing AAV9. DNA was digested with the indicated restriction enzymes. The wild-type locus produced hybridization bands at 4.3 and 13 kb, the KitlSl locus produced no bands, and the KitlSl-d locus produced bands at 4.3 and 7 kb.

Scale bars, 1 mm (A, upper panels) and 40 μm (A, middle and lower panels; B). Counterstain, H&E (A, middle) and Hoechst 33342 (A, bottom; B). See also Figure S7 and Table S1.
