tumors of the testis after orchiopexy.
Nuclei Measurements of Germinal Cells
. The diameters of germinal cell
nuclei were calculated by measuring 20 nuclei of each cell type at cross sections of seminiferous tubule stages, with the exception of elongated spermatids, in which the lengths of nuclei in the cells were measured.
The mean thickness of the germinal cell
layer and the mean diameter of the seminiferous tubules in the androgen-deprived 400 mg/kg group were significantly increased in comparison with those in the androgen-deprived control group (Table 1).
Another important finding was the increase in TUNEL-positive cells in the germinal epithelium which was consistent with germinal cell
Key words: seminoma, metastasis, germinal cell
, electron microscopy, avian, cockatiel, Nymphicus hollandicus
The HCG hormone test is an accepted tumor marker for germinal cell
Eight primary germinal cell
tumors of the ovary were studied.
It was calculated as the diameter of germinal cell
layer divided by the width of the seminiferous tubule .
The Sertoli cell, considered as a nurse cell for the germinal cells
, elaborates a protein binder of androgens (ABP) that would be a facilitator to transfer testosterone to a receiving germinal cell
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.
Meiotic arrest of germinal cells
is characterized by being able to enter the stages of meiosis but failing to continue the division process.
The germinal cells
will undergo a series of divisions and ultimately develop into spermatozoa.
