Interacciones epitelio-mesenquimáticas en el desarrollo testicular

Int. j. morphol; 35 (4), 2017
RESUMEN: La espermatogénesis es un proceso continuo que se inicia durante el desarrollo embriofetal. Las relaciones auto, para y yuxtacrinas indican la interdependencia de las células intersticiales (de Leydig) con las células peritubulares (lamina propia) y células sustentaculares (de Sertoli). Cier...

Inductive role of sustentacular cells (Sertoli cells) conditioned medium on bone marrow derived mesenchymal stem cells

Int. j. morphol; 35 (4), 2017
RESUMEN: Las células madre de la línea germinal masculina son factores clave para la espermatogénesis masculina y la fertilidad. Las células sustentaculares (células de Sertoli) como células somáticas juegan un papel fundamental en la creación de un microambiente esencial para la auto-renovación...

The quantification of testicular cells during the postnatal development in two Caviomorph rodents: the guinea pig (Cavia porcellus) and the cutia (Dasyprocta agouti)

An. acad. bras. ciênc; 89 (3), 2017
ABSTRACT The germinative, Sertoli and Leydig cells of two caviomorph rodents (Cavia porcellus and Dasyprocta agouti) were counted as well as the estimation of the total volume of the testis and the total volume of seminiferous tubules and interstitium in prepubertal, pubertal and adult animals. The numbe...

Differential expression and localization of ADAM10 and ADAM17 during rat spermatogenesis suggest a role in germ cell differentiation

Biol. Res; 47 (), 2014
BACKGROUND: Extracellular metolloproteases have been implied in different process such as cell death, differentiation and migration. Membrane-bound metalloproteases of the ADAM family shed the extracellular domain of many cytokines and receptor controlling auto and para/juxtacrine cell signaling in diffe...
