GC-1 mRHBDD1 knockdown spermatogonia cells lose their spermatogenic capacity in mouse seminiferous tubules [PDF]

open access: yesBMC Cell Biology, 2009
Background Apoptosis is important for regulating spermatogenesis. The protein mRHBDD1 (mouse homolog of human RHBDD1)/rRHBDD1 (rat homolog of human RHBDD1) is highly expressed in the testis and is involved in apoptosis of spermatogonia.

Sperm proteins and cancer-testis antigens are released by the seminiferous tubules in mice and men. [PDF]

open access: yesFASEB J, 2021
Sperm develop from puberty in the seminiferous tubules, inside the blood-testis barrier to prevent their recognition as “non-self” by the immune system, and it is widely assumed that human sperm-specific proteins cannot access the circulatory or immune ...

Effects of Crocin on Sperm Parameters and Seminiferous Tubules in Diabetic Rats. [PDF]

open access: yesAdv Biomed Res, 2019
Background: Diabetes can increase the generation of free radicals and can be harmfully effective in spermatogenesis. Crocin is a carotenoid and is accountable for the red color of saffron.

Three-dimensional morphological analysis of spermatogenesis in aged mouse testes

open access: yesScientific Reports, 2021
Spermatogenesis, which is a continuous process from undifferentiated spermatogonia to spermatozoa in the seminiferous tubules, declines with age. To investigate changes in spermatogenesis with aging, we reconstructed the seminiferous tubules of 12 mice ...
