However, for most of the germ tubes (or germ tube-like structures) and short filaments formed by age3Δ blastospores, actin patches were scattered along the cell bodies and a polarization pattern was rarely observed.
We hypothesized that the regions excluding Pol II might be the X chromosomes, because the X chromosome is specifically silenced during larval and adult germ cell development, carries strikingly few germline-specific genes, and is thus a largely inert chromosome in most stages of germ cell development [ 20, 21].
However, in the CCl4-treated group, differences were observed in the histology of testes, where complete swallowing of seminiferous tubules was exhibited while in other areas of the section the tubular basement membranes of seminiferous tubules were identified, but most of the germ cells were degenerated, especially the ones involving highly differentiated germ cells along with deformed sperm.
In our patient, histology shows severe hypospermatogenesis with most of the germ cells arrested at the spermatocyte stage.
Since most of male germ cells develop after the immune system is fully functional, they are autoimmunogenic [ 26].
Irradiation of KO mice, however, lead to strong depletion in most of the germ cell subpopulations of the adult testis eventhough mice are still fertile.
Germ cells in the XY gonad have been reported to enter G1/G0 arrest from 12.5 dpc onwards, and this arrest is complete for most of the germ cells by 14.5 dpc (Western et al., 2008).
In contrast, refined grains lack most of the germ and bran, which are removed during milling, resulting in the loss of numerous health-conferring constituents such as fiber, vitamins, minerals, lignans, resistant starch, phenolic compounds and phytochemicals [ 61].
In P2 control testis, most of round germ cells (gonocytes) labeled with MVH were shown to localize within the center of testicular cord, whereas Sertoli cells were positioned close to the basement membrane.
