Identification of androgen binding-protein(ABP)from testis and epididymis of the seasonal rodent, Octodon degus(Molina, 1872)
androgen binding-protein (ABP) testis seasonal rodent Octodon degus (Molina, 1872)
2009/2/23
ABP, a Sertoli cell secretory product, was identified in the seasonal rodent Octodon degus (Molina, 1872). It was shown to be present in cytosols from the testis and epididymis. It migrated with a...
Testicular and serum testosterone variations in squirrel monkeys during seasonal cyclicity
serum testosterone variations squirrel monkeys seasonal cyclicity
2009/2/23
The seasonal testicular maturation of squirrel monkeys (Saimiri sciureus) was used as a model of maturational hormonal regulation of the testis. Testicular testosterone and serum testosterone concen...
The distribution of connexin 43 is associated with the germ cell differentiation and with the modulation of the Sertoli cell junctional barrier in continual(guinea pig)and seasonal breeders'(mink)testes
Gap junction Cx43 Sertoli cell blood-testis barrier
2009/2/13
To test whether the gap junction protein connexin 43 (Cx43) is associated with germ cell differentiation and with the Sertoli cell junctional blood barrier, we recorded the temporal changes in its d...
