Integrative Zoology, EarlyView.The increase in salinity leads to changes in the gut microbiota and metabolites of Trachemys scripta elegans, affecting the synthesis and secretion of neurotransmitters or precursors, which can inhibit the secretion of reproductive hormones and affect the self‐renewal and differentiation process of spermatogonial stem cells.

Enrichment of Spermatogonial Stem Cells using Side Population in Teleost [PDF]
, 2014 Spermatogenesis originates from a small population of spermatogonial stem cells; this population can maintain continuous sperm production throughout the life of fish via self-renewal and differentiation.

The use of deidentified organ donor testes for research
Andrology, EarlyView.Abstract Our knowledge of testis development and function mainly comes from research using mammalian model organisms, primarily the mouse. However, there are integral differences between men and other mammalian species regarding cellular composition and expression profiles during fetal and post‐natal testis development and in the mature testis ...

Sperm Telomere Interactions Are Impaired in Testicular Cancer Before and After Adjuvant Therapy
Andrology, EarlyView.ABSTRACT Background No study has yet explored telomere length or interaction in sperm nuclei of testicular cancer (TC) patients exposed to chemotherapy or radiotherapy. However, sperm telomere dynamics have emerged as a potential marker in male infertility.

Melatonin improves spermatogonial stem cells transplantation efficiency in azoospermic mice [PDF]
Iranian Journal of Basic Medical Sciences, 2014 Objective(s):Transplantation quality improvement and reduction of cellular damage are important goals that are now considered by researchers. Melatonin is secreted from the pineal gland and some organs such as testes.

Andrology, EarlyView.ABSTRACT Testicular germ cell tumors (TGCT) are the leading malignancy in adolescent and young adult males, yet the immunological and cellular mechanisms governing their tumor microenvironment (TME) remain poorly understood. Here, we present a comprehensive review of TGCT pathobiology with a focus on the immune landscape, particularly the role of tumor‐

Deriving bovine embryonic stem-like cells in defined conditions [PDF]
, 2011 The first embryonic stem ES cell line was isolated from mouse in 1981 (Evans and Kaufman 1981; Martin1981). However, ESCs are only available in rodent species.
