Regulation of boundary cap neural crest stem cell differentiation after transplantation [PDF]

, 2009
Success of cell replacement therapies for neurological disorders will depend largely on the optimization of strategies to enhance viability and control the developmental fate of stem cells after transplantation.

The Impact of Common Medications on Male Fertility: An Updated Systematic Review

Andrology, EarlyView.
ABSTRACT Background Compared with those of cytotoxic treatments, the potential effects of common medications on the fertility of men trying to conceive currently or planning to conceive in the future are less well described. The use of common medications may modify the gonadotropic axis, spermatogenesis, and epididymal maturation or alter male ...

Dielectrophoresis: A Review of Applications for Stem Cell Research [PDF]

, 2010
Dielectrophoresis can discriminate distinct cellular identities in heterogeneous populations, and monitor cell state changes associated with activation and clonal expansion, apoptosis, and necrosis, without the need for biochemical labels.

Pubertal Dynamics of Sertoli and Leydig Cell Dysfunction in Klinefelter Syndrome

Clinical Endocrinology, EarlyView.
ABSTRACT Context Klinefelter syndrome (KS), defined by a 47, XXY karyotype, is commonly associated with progressive testicular failure. The precise timing of Sertoli and Leydig cell dysfunction during puberty remains unclear. Objective To determine the onset and progression of testicular insufficiency during puberty in KS, and to assess whether ...

Human stem Leydig cells

, 2021
Hypogonadism, a clinical condition due to low testosterone levels is associated with increased visceral fat, decreased muscle mass, erectile dysfunction, reduced libido, depression and changes in mood. Hypogonadism might occur after testicular sperm extraction, although its exact effect on testosterone levels and consequently the risk on hypogonadism ...

Differentiation of human induced pluripotent stem cells into Leydig-like cells with molecular compounds [PDF]

Cell Death & Disease, 2019
AbstractLeydig cells (LCs) play crucial roles in producing testosterone, which is critical in the regulation of male reproduction and development. Low levels of testosterone will lead to male hypogonadism. LC transplantation is a promising alternative therapy for male hypogonadism.

Distribution of interstitial stem cells in Hydra [PDF]

, 1980
The distribution of interstitial stem cells along the Hydra body column was determined using a simplified cloning assay. The assay measures stem cells as clone-forming units (CFU) in aggregates of nitrogen mustard inactivated Hydra tissue.

A Noncanonical Protein Degradation Pathway That Regulates Germ Cell Maintenance

Cell Proliferation, EarlyView.
SENP8 regulates a non‐canonical NEDD8‐dependent pathway to stabilize STAT1, promote CCL2/CCL5 transcription, and maintain germ cell proliferation and migration.

Effect of FSH on testicular morphology and spermatogenesis in gonadotrophin-deficient hypogonadal mice lacking androgen receptors [PDF]

, 2010
Follicle stimulating hormone (FSH) and androgen act to stimulate and maintain spermatogenesis. FSH acts directly on the Sertoli cells to stimulate germ cell number and acts indirectly to increase androgen production by the Leydig cells.

GSK3α‐mediated regulation of the RNA demethylase fat mass and obesity‐associated protein (FTO) during murine spermatogenesis

The FEBS Journal, EarlyView.
FTO regulates mRNA stability and translational efficiency through its m6A‐demethylation activity. GSK3 functions as an upstream regulator of FTO, leading to its inhibition via phosphorylation. In male germ cells, FTO activity is kept in check by GSK3α.
