(10,12,20) An additional feature of pre-GCNIS is the expression of stem cell factor (also known as KIT ligand) in the seminiferous tubules
having pre-GCNIS; this is also a feature of GCNIS but is absent in maturation delay.
Ameliorative effects of curcumin on the structural parameters of seminiferous tubules
and Leydig cells in metronidazole-treated mice: a stereological approach.
Alkaline phosphatase (ALP) is found in interstitial cells, seminiferous tubule
and basement membrane, playing a key role in transfer of materials from sertoli cells to germinal cells and growth of the germinal epithelium20.
Testis of rat from group 1 showing the normal histological structure of seminiferous tubules
, normal spermatogenesis (stage VIII tubule).
(A) Seminiferous tubules
of control group with normal conjoined germinative epithelial cells and spermatozoa in the lumen.
The data indicated the significantly higher percentage of seminiferous tubules
containing MNGCs in the AA-treated group than in the AA+L-cys-treated group (p<0.001), as shown in Table 3.
This finding could have resulted in slight suppression of scrotal circumference growth, testicular weight, length, breadth and spermatogenesis in seminiferous tubules
at week 30 after the primary immunization.
The low expression rate of CDC25A in infertile men is the result of the reduction of spermatogenic cycles in the seminiferous tubules
and shows that the CDC25 phosphatase contributes to the hyperphosphorylation of M-phase promoting factor (MPF) and CDC25 that are important to complete the meiosis (24).
The positive cells in the tubular compartments were distributed in the spermatogenic cells and Sertoli cells of the seminiferous tubules
Type A spermatogonia at the basal lamina of seminiferous tubules
, as well as primary spermatocytes in the leptotene and pachytene stages of prophase I, were also observed in the seminiferous epithelium.
Irregular seminiferous tubules
and relatively decreased diameter of seminiferous tubules
could be observed.
4A) and are histologically constituted of seminiferous tubules
which contain spermatogenic cells (Fig.
Objective: To demonstrate the morphological changes in number of seminiferous tubules
that are produced by anthracycline doxorubicin on the testes of mice.
Sections were examined for Johnson scoring, diameter of seminiferous tubules
, thickness of germinal epithelium.
Thus, diabetic patients have an increase in apoptosis levels within the seminiferous tubules
which may be linked to the reduction of steroidogenesis and increase in ROS production.
