Transduction Kinetics Analyzed by Microinjection of AAV9-Cre into R26R-Eyfp Mice
(A) Macroscopic appearance of R26R-Eyfp mouse testes at indicated time points after AAV9-Cre microinjection.
(B) Immunostaining of R26R-Eyfp mouse testes for undifferentiated spermatogonia (GFRA1) and Sertoli cell (WT1) markers.
(C) Real-time PCR analysis of Gdnf, Fgf2, and Kitl expression in wild-type untreated and busulfan-treated testes 2 days after microinjection. Three testes from three different animals were used (n = 3).
(D) Immunostaining of CLDN11 1 week after microinjection with AAV1- or AAV9-mCherry.
(E) Functional assessment of the BTB. Wild-type and Cldn11 KO mouse testes transduced with AAV8-, AAV1-, or AAV9-mCherry were injected interstitially with biotin (green). Samples were recovered 30 min after microinjection (n= 3).
