Sentence examples for germ cells such from inspiring English sources

During spermatogenesis, the movement of developing germ cells across the seminiferous epithelium involves the restructuring of adherens junctions that form between Sertoli cells and between Sertoli and germ cells such as the ectoplasmic specialization (ES).

At present it is illegal to alter the genes of reproductive "germ cells" such as eggs, sperm and embryos, but the clinical benefits of modifying the human germ-line could one day outweigh the ethical objections, says a statement by two government research councils and a coalition of medical research charities.

We have previously characterized in vitro-generated OLCs, demonstrating that they morphologically resemble oocytes and express markers associated with mature germ cells such as Oct4, Vasa, and Gdf9b [21].

Spermatogonia are highly tolerant to reactive oxygen species (ROS) attack while advanced-stage germ cells such as spermatozoa are much more susceptible, but the precise reason for this variation in ROS tolerance remains unknown.

Strong expression of Cu/Zn SOD was observed in type A and B spermatogonia, but expression was weak in more advanced germ cells such as spermatocytes, spermatids, and spermatozoa (Figure 2C).

In the male, the Dazl−/− mutant germ cells had decreased expression of early markers of pluripotent germ cells such as Nanos2, Nanos3, Pum2, Stella, and Oct-4, and even larger decreases in the expression of meiotic markers such as Sycp3 and Sycp1, relative to the wildtype cells at E13.5, 14.5 and 15.5 (Figure 2A, 2C, and 2E).

The remaining 15% of all ovarian cancers are germ cell tumors (such as teratomas, dysgerminomas and yolk sac tumors), sex cord stromal tumors (such as fibromas and thecomas) and least commonly, metastatic ovarian cancer from other primary tumors, particularly those of gastric, colonic and pancreatic origin (Table 2).

In addition, the expression of other germ cell markers, such as NANOS and PIWIL1 genes, was also up-regulated as the EB differentiation progressed.

Thus, multiple systems may exist to regulate post-transcriptional germ cell functions such as mRNA transport through intercellular bridges (if it is regulated) and translation.

By using germ cell markers such as SSEA1, OCT-4, and VASA, the identification and characterization of germ cell differentiation from ES cells is possible in vitro as well as in vivo.

The genes that are regulated by Nanos2 during germ cell development, such as Stra8, Dnmt3L and Tdrd, are unchanged in hypothalamus after neonatal starvation in our microarray data set.
