the spermatogonial stem cells (sscs) are founder of spermatogenesis and they are the only stem cells that can transmit genetic materials to offspring’s. this research was conducted to achieving a reliable origin of sscs from the goat testicular tissues according to a four steps procedure; a) collection and preparing testicular tissues, b) two enzymatic digestions, c) using mesh and cell suspens...

background: zinc (zn) as an important trace element is essential for testicular development and spermatogenesis. molecular mechanism of zn action in the reproductive system may be related to metal binding low-molecular weight proteins, metallothioneins (mt). our objective was to determine the effect of zn on two important isoforms of mt, mt1m and mt1g genes expression on testicular sertoli cell...

Nicotinamide phosphoribosyltransferase (NAMPT) is a cytokine hormone and rate-limiting enzyme involved in production of NAD and therefore affects a variety of cellular functions requiring NAD. Spermatogenesis and testicular steroidogenesis are likely to depend on NAD-dependent reactions and may therefore be affected by changes in testicular NAMPT expression. The objectives of the present study ...

This study was designed to determine the testicular abnormalities in rams slaughtered Sokoto, Nigeria. The testicles of presented for slaughter were examined, and age, breed, position, sites noted. Out 638 3 had abnormalities, representing a prevalence 0.47%, comprising 2 (0.31%) unilateral cryptorchidism 1 (0.16%) hypoplasia. (0.58% (2/342) 0.34% (1/296) obtained at Sokoto metropolitan abattoi...

Background: Bovine follicle stimulating hormone (bFSH) belongs to the family of glycoprotein hormones that are released from the pituitary gland or the placenta. This hormone is a heterodimer consisting of common α- and specific β-subunit. Bovine FSH is used for reproductive technology such as superovulation in farm animals and polycystic ovary syndrome treatment. Also this hormone is produced ...

So far, successful de novo formation of testicular tissue followed by complete spermatogenesis in vitro has been achieved only in rodents. Our findings reveal that primary human testicular cells are able to self-organize into human testicular organoids (TOs), i.e., multi-cellular tissue surrogates, either with or without support of a biological scaffold. Despite lacking testis-specific topograp...

Aim: The use of self-adhesive composites in dental treatment relatively a new concept. aim this study was to in-vitro evaluation cytotoxicity Vertise Flow and Nova Compo SF flowable on bovine pulp-derived cells. 
 Material method: Experimental test samples (2×5mm) were prepared. Bovine cells incubated MEM-Alpha (Gibco-Invitrogen). material be tested stored the culture medium for 24 hours t...

Background: The buffalo (Bubalus bubalis) is the animal with special production characteristics in producing milk and meat has a critical role in rural industry in Iran. The most problem of this specie is its low reproductive output. The aim of the present study was to evaluate the effect of bovine cumulus co-culture on maturation rate of Buffalo oocyte.Materials and Methods: Ovaries were colle...

In this study, primary and immortalized bovine intestinal epithelial cells (BIECs) were characterized for the expression of surface carbohydrate moieties. Primary BIEC-c4 showed staining greater than 90 % 16 lectins but less 50 four lectins. Immortalized BIECs significantly different lectin binding profile few compared to cells. studied infectivity E. coli, Salmonella enterica, rotavirus, coron...
