germ cells

There was a profound defect in interactions of parental chromosomes, a process known as synapsis , leading to death of germ cells.

As the embryo develops, the foreign gene may be present in many cells of the body, including the germ cells of the testis or the ovary.

Meiosis comprises a pair of specialized nuclear divisions that produce haploid germ cells.

Recently, it has been shown that germ-cells, too, are subject to epigenetic change, sometimes in response to environmental stimuli.

Mendel'swork found that alleles assort independently in the production ofgametes, or germ cells, ensuring variation in the next generation.

This is the microscopic appearance of normal testis. The seminiferous tubules have numerous germ cells. Sertoli cells are inconspicuous.

Methods: Using germ cells in meiosis as material to make sections, the changes of meiosis phases of spermatocyte were analyzed.

This article updates the researches on the culture of primordial germ cells and stem cells'differentiation into male gamete.

Note the difference in size and staining quality of the neoplastic nests of cells compared to normal germ cells.

CONCLUSION? Primordial germ cells and female and male germ cells in the in vivo normal development process or cultured in vitro would die.

Adults are infertile due to lack of mature germ cells, and 50% develop hydronephrosis due to ureteral hyperplasia.

Aggregation substance mediates conjugation of plasmids, aggregation and binding of eukaryocytes with other germ cells.

The haploid organism's germ cells then combine with another haploid organism's cells, creating the zygote.

He has begun studies of the role of germ cells (egg and sperm) in initiating the process by which an embryo becomes anatomically female.

Conclusion : It is suggested that SP can significantly inhibit the mutagenesis of germ cells and somatic cells induced by CP.

Hereditary diseases refer to the diseases caused by the change of germ cells or hereditary substance in fertilized ova .

The epigenetic profile of germ cells, which is defined by modifications of DNA and chromatin, changes dynamically during their development.

Many insects, and also nematodes, consist of post-mitotic cells, apart from germ cells.

In this sense, germ cells are mother cells of all stem cells, since they produce new organisms rather than organs.

Endodermal sinus tumor arises from the primitive germ cells or Polyderivative embryonic cells.

Objective: To isolate and clone bovine embryonic stem cells from bovine fetus Primordial germ cells(PGCs).

But as Baumann's group shows, A. tesselata germ cells start with four sets of chromosome copies, not two.

The germ cells are unmodified by these activities.

In this review, we will introduce the progress on derivation of male germ cells from ESCs and ASCs.

MeHg is a confirmed teratogen in human. It can impair the germ cells and influence the growth and development of the offspring.
