Thyroid Hormone Regulates Postnatal Development of the Rete Testis in Mice.

Thyroid hormone regulates the rate of testis maturation in mammals. Manipulations of thyroid hormone levels in neonatal animals affect various aspects of testis biology. However, there have been no studies examining the effects of thyroid hormone on the rete testis (RT).

A comparative analysis of genes differentially expressed between rete testis cells and Sertoli cells of the mouse testis.

The rete testis (RT) is a region of the mammalian testis that plays an important role in testicular physiology. The RT epithelium consists of cells sharing some well-known gene markers with supporting Sertoli cells (SCs). However, little is known about the differences in gene expression between these two cell populations.

spermatogenesis: In search of fully defined conditions.

A complete reconstruction of spermatogenesis under fully defined conditions still has not been achieved. However, many techniques have been proposed to get closer to that aim. Here we review the current progress in the field.

A mechanism of self-lipid endocytosis mediated by the receptor Mincle.

Cellular lipid uptake (through endocytosis) is a basic physiological process. Dysregulation of this process underlies the pathogenesis of diseases such as atherosclerosis, obesity, diabetes, and cancer. However, to date, only some mechanisms of lipid endocytosis have been discovered.

Establishment of a pure culture of immature Sertoli cells by PDGFRA staining and cell sorting.

Sertoli cells are key somatic cells in the testis that form seminiferous tubules and support spermatogenesis. The isolation of pure Sertoli cells is important for their study. However, it is a difficult effort because of the close association of Sertoli cells with peritubular myoid cells surrounding seminiferous tubules.
