Androgen receptor signalling in peritubular myoid cells is essential for normal differentiation and function of adult Leydig cells

Autor: Kirstine Belling, Philippa T. K. Saunders, L. R. de Franca, T. M. Segatelli, Lee B. Smith, Lindsey Moffat, Michelle Welsh, Richard M. Sharpe

Publikováno v: International Journal of Andrology. 35:25-40

Testosterone synthesis depends on normal Leydig cell (LC) development, but the mechanisms controlling this development remain unclear. We recently demonstrated that androgen receptor (AR) ablation from a proportion of testicular peritubular myoid cel

Sertoli cells in testes containing or lacking germ cells: A comparative study of paracrine effects using the W (c-kit) gene mutant mouse model

Autor: Andrzej Bartke, Ahmed Yagi, Lonnie D. Russell, Kurt E. Borg, L R De Franca, Clare Fadden, Marcelo Cecim

Publikováno v: The Anatomical Record. 240:225-232

Background: Paracrine effects of germ cells on Sertoli cell structure were examined in a mouse model with the W locus (dominant white spotting) mutation in which animals with the W/Wv genotype (referred to as mutants) lack virtually all germ cells. R

Surface and Surface-to-Volume Relationships of the Sertoli Cell during the Cycle of the Seminiferous Epithelium in the Rat1

Autor: L R De Franca, Lonnie D. Russell, Sushmita Ghosh, Shi-Jun Ye

Publikováno v: Biology of Reproduction. 49:1215-1228

The surface relationships of the Sertoli cell and the surface relationships of the Sertoli cell in comparison to the changing volumes of developing germ cells were studied using morphometric techniques at periods representing nine groupings of the fo

Spermatogonial morphology, kinetics and niches in hamsters exposed to short- and long-photoperiod

Autor: L. R. de Franca, Hélio Chiarini-Garcia, A. L. Drumond, H. F. Do Nascimento

Publikováno v: International journal of andrology. 32(5)

Previous studies have shown that under short photoperiod exposure spermatogenesis in golden hamster regresses leading to sexual inactivity. It is known that this regression is related to changes in somatic and germ cells (spermatocytes and spermatids

Recombinant human follicle-stimulating hormone is capable of exerting a biological effect in the adult hypophysectomized rat by reducing the numbers of degenerating germ cells

Autor: Andrzej Bartke, K E Borg, T J Corbin, L R De Franca, P Grasso, Lonnie D. Russell

Publikováno v: Endocrinology. 133(5)

There is considerable controversy as to whether FSH can, under normal circumstances, exert an effect to promote spermatogenesis in the adult rat. Recombinant human FSH (rhFSH) was used to answer a more limited question relating to whether FSH is capa
