TS23: seminiferous cord		Strong	Regionally restricted	5A	Strong hybridization signal was detected in gonocytes.
TS23: Sertoli cell	Sertoli cell	Weak		5A	Weaker signal was observed in Sertoli cell cytoplasm.
TS23: interstitium of the testis		Present		5A

TS28: germ cell of testis	Present		6A	Hybridization signal was detected on most types of germ cell. Signal was detectable in meiotic and post-meiotic cells within the adluminal compartment. However, the intensity of signal was considerable lower than in the basally-located cells.
TS28: primary spermatocyte	Present		6A	Most abundant expression was detected in spermatogonia or early primary spermatocytes.
TS28: spermatogonium	Present		6A	Most abundant expression was detected in spermatogonia or early primary spermatocytes.
