In mammals, the apoptosis of germ cells is an integral part of spermatogenesis, occurring normally in several phases of development (BLANCO-RODRIGUEZ; MARTINEZ-GARCIA, 1996).
Very high CSF concentrations (>1000IU/L) suggest the presence of nongerminomatous germ cell tumors, which are usually refractory to treatment.
The most common presenting symptoms for patients with suprasellar germ cell tumors are diabetes insipidus, visual field defects, and hypothalamic-pituitary abnormalities such as hypopituitarism, delayed sexual development, growth failure, and precocious puberty.
Second, the investigators identified germ cells in juvenile and adult mouse ovaries expressing marker proteins required for the initiation of meiosis in mammals.
The scientists hope studying cultured germ cells might provide clues to how various processes work.
Remember, ourimmortal germ cells activate the gene that produces the enzyme telomerase, which restores the ends of their telomeres whenever they divide.
Because all germ cells in the perinatal rat testis immunostain intensely for VASA in the cytoplasm, we were able to use VASA immunohistochemistry to develop an objective method for measuring germ cell aggregation, based on average germ cell cluster size, in testes from control and DBP-exposed rats at E17.
flox/flox] mice: To specifically investigate the role of each Fgfr1 and Fgfr2 in germ cells, a transgenic Cre mouse line expressing an improved Cre (iCre) recombinase driven by the mouse Tex101 promoter (Tex101-iCre) was used.
The research at the Stanford University School of Medicine and Montana State University suggests that the men with azoospermia may have had germ cells at some point in their early lives, but lost them as they matured to adulthood.
But live mouse offspring can be generated with assisted reproduction using germ cells from males with the Y chromosome contribution limited to only two genes.
In mice, germ cells, which give rise to sperm and eggs, undergo a thorough cleaning: Most chemical tags get erased.
In cases where undifferentiated germ cells are present in the testis, strategies based on sperm development from spermatogonial stem cells (SSCs) in vitro or in vivo need to be established.
