Expression data from testes fragment of 7-week-old W/Wv mouse testes

In the terminal end of the seminiferous tubules adjacent to rete testis (RT), there are valve-like structures called Sertoli valve (SV) epithelia. SV epithelia are constitutively missing most spermatogenesis activity partially through high GDNF expression, leading to the SV-specific enrichment of undifferentiated spermatogonia. We used microarrays to elucidate the molecular characterization in the SV epithelia. RT, SV and convoluted seminiferous epithelia (ST) samples were obtained from 7-week-old W/Wv mouse testes. 20 testes were used for 1 analysis and 3 biological replicates of each region were analyzed.
