| The seminiferous tubules were gently pelleted and subjected to proteinase digestion and DNA extraction. |
|
| It takes three months for the seminiferous tubules of the testes to produce sperm which is then stored in the epididymis. |
|
| The seminiferous tubules in the testes, which are the origin of the sperm cells, however, will be reduced in diameter and size. |
|
| The passage of sperm from the seminiferous tubules of the testis to the vas deferens takes about 12 days. |
|
| Three trained observers reviewed each stallion's histology slides by quantifying the number of spermatids within 25 cross-sectioned round seminiferous tubules. |
|
| The seminiferous epithelium in most tubules comprised only a layer of spermatogonia and Sertoli cells. |
|
| Leading from the seminiferous tubules are the tubuli recti or straight tubules lined only with columnar cells apparently derived from Sertoli cells. |
|
| Following the postmeiotic phase, spermatozoa are released into the lumen of the seminiferous tubule of the testis and transported to the epididymis for storage. |
|
| At 109 and 110 day-old sturgeon, developing testicular tissue was observed and included the presence of seminiferous tubules and vas deferens. |
|
| Study on male cattle's sterility by investigating the historical characteristics of anterior pituitaries and convoluted seminiferous tubulus. |
|
| The evaluation of cell population was based on the calculation made for each cell type per cross section of the seminiferous tubule. |
|
| Seasonality was determined by changes in relative and total testis weight, and in seminiferous tubule diameters. |
|
| Factors such as viruses, anticancer drugs, hormones, radiation and toxic materials, including cadmium, induce cell death in seminiferous tubules. |
|
| The blood-testis barrier is a physical barrier between the blood vessels and the seminiferous tubules of the testes. |
|
| The seminiferous tubules may be preserved, atrophic, or completely obliterated. |
|
| The seminiferous tubules, sperm counts, and testosterone levels of BPA-exposed mice were also not significantly different. |
|
| This process promotes the maturation of the seminiferous tubules and spermatogenesis. |
|
| In addition, the expression of miR-34c was upregulated rapidly indicating that mi-34c was important for the growth of seminiferous tubules. |
|
| The spermatogonia mature into spermatocytes, which mature into spermatids that mature into spermatozoa as they move into the central lumen of the seminiferous tubule. |
|
| The stroma which joins all the seminiferous tubules contains LEYDIG cells which produce the androgens essential for spermatogenesis amongst other things. |
|
|
|
| Also, there was disorganization of plasmalemma in the basal portion of few seminiferous tubules. |
|
| The SERTOLI cells which line the basal membrane of the seminiferous tubules and surround the germinal cells throughout their maturation to spermatazoids. |
|
| Their seminiferous tubules are not normal. |
|
| Testicular dysgenesis affecting the seminiferous tubules principally, with chromatin-positive nuclei. |
|
| Lumina of the seminiferous tubules were lined by spermatozoa and rows of metamorphosing spermatids. |
|
| Spermatozoa move to the epididymis by the flow of fluid into the lumen of the seminiferous tubules from the adluminal spaces. |
|
| The process of spermatogenesis takes place within the coiled seminiferous tubules, and continues from puberty to old age. |
|
| The splenic tissue was separated from the seminiferous tubules by a splenic capsule and vascular fibrous connective tissue. |
|
| Among males, presence of convoluted epididymides and spermatozoa in seminiferous tubules and epididymides were used to define minimum size at sexual maturity. |
|
| Two of the affected seminiferous tubules contain numerous macrophages phagocytosing sperm, whereas only a few remaining spermatogonia can be identified. |
|
| The structural basis for the SSC niche in the mammalian testis is the basal compartment of the seminiferous tubules and omposed of sertoli cells and peritubular myoid cells. |
|
| The tubular structure of both testes was completely replaced by the neoplastic growth, except for a few seminiferous tubules randomly scattered throughout the mass. |
|
| Seminiferous tubule diameter measurement was carried out using a linear scale-ocular micrometer inserted into the eyepiece. |
