Expression profile of human CDY mRNA in the testis. Reverse transcription–PCR detection of CDY mRNA in testis samples from a normal male, three males with germ cell maturation arrest, and one male with Sertoli cell only syndrome. The widely expressed CDYL (11) is used as a positive control for the reverse transcription–PCR assay. DAZL is used as a marker for spermatogonia and spermatocytes (25). PRM1 is used as a marker for late-phase round spermatids and elongating spermatids (26).
