Sites of transcription of the Müllerian inhibiting substance gene in mouse testis.
We have examined the transcription of Müllerian inhibiting substance (MIS) in testis by the sensitive technique of reverse transcription polymerase chain reaction (RTPCR). A developmental study of testis by this nonquantitative technique showed expression at all postnatal stages, including adults while liver and kidney provided negative controls. Cell separation studies indicated that highly purified interstitial cells, as well as less homogeneous Sertoli cell-enriched and germ cell-enriched fractions, contained RNA for MIS. The transcription of MIS in an interstitial cell type was confirmed by finding MIS mRNA in purified Leydig cells. Inasmuch as the germ cell-enriched fraction contains some Sertoli cells, and XX,Sxra and XX,Sxrb which have germ cell-depleted testes, contain MIS mRNA, a Sertoli cell source remains likely for the seminiferous tubule compartment.
