The aim of the study was to compare the terminal parts of testicular artery topography in human and bovine gonads. The study was made on two extremely different types of location of the mediastinum testis. The investigation was carried out on 80 (40 human and 40 bovine) corrosive casts of the testicular arteries. The differences between the species, including the different course of the testicu...

The posttranscriptional gene regulation mediated by microRNA plays an important role in the development and function of male and female reproductive organs and germ cells in mammals, including cattle. In the present study, we identified novel and differentially expressed miRNAs in the testis and ovary in Holstein cattle by combining the Solexa sequencing with bioinformatics. In total 100 and 10...

BACKGROUND Proper blood supply is necessary for the physiological function of every internal organ. The article offers the first classification of the bovine intra-testicular arteries. A corrosive study focused on the intra-testicular arterial vasculature was performed on 40 bovine testes. The vessels were analyzed accurately using MultiScanBase v.18.02 software. METHODS A corrosive study foc...

Background: More than a decade work in preservation of male fertility by spermatogonial stem cell (SSC) transplantation in animal models as well as new discoveries about the nature of human SSCs has prompted an investigation into the possibility of an effective clinicalgrade procedure for isolation and cryopreservation of human testicular cells. Materials and Methods: Clinical-grade reagents, v...

In this syudy a continuous bovine kidney cell line derived from a primary bovine kidney cells was established for the first time in Iran. The cells were originating from two-day-old normal male calf of Holstein breed. The cell cultures were continuously passaged following complete proliferation of primary cells. The specific properties or characteristics of the cell were defined using cytogenet...

objective: spermatogonial stem cells (sscs) are the only cell type that can restore fertility to an infertile recipient following transplantation. much effort has been made to develop a protocol for differentiating isolated sscs in vitro. recently, three-dimensional (3d) culture system has been introduced as an appropriate microenvironment for clonal expansion and differentiation of sscs. this ...

conclusions in this study, the l-lps immune response of bovine cells was significant, indicating that tlr2 is the predominant receptor for l-lps. due to l-lps endotoxin-like activity, we found a strategy through using bmap-28 to prevent l-lps-induced tlr2-dependent immune activation in bovine cells. materials and methods in this study, l-lps-induced proinflammatory cytokine production in bovine...

A simple method for preparing plasma membranes from bovine testes is described. Bovine testicular receptor has a high affinity and specificity for 125I-labelled human FSH (follicle-stimulating hormone). The specific binding of 125I-labelled human FSH to the plasma membranes is a saturable process with respect to the amounts of receptor protein and FSH added. The association and dissociation of ...
