The term often also refers to the primordial germ cells.

It is also expressed in the primordial germ cells of females.

Another dramatic migration is that performed by the primordial germ cells (Chapter 9).

Also, Primordial germ cells are first found in the wall of the yolk sac.

This is where the primordial germ cells collect.

However, gametogonia are themselves successors of primordial germ cells.

Recent studies have demonstrated that it is possible to give rise to primordial germ cells from ES.

In the absence of the Sry gene, primordial germ cells differentiate into eggs.

Discussion Primordial germs cells originate from a small number of progenitor cells that arise in very early development.

These considerations led to his proposal that cancer cells, like trophoblasts, arise from primordial germ cells.

Microscopic examination typically reveals uniform cells that resemble primordial germ cells.

After migration primordial germ cells will become oogonia in the forming gonad (ovary).

Germinomas are thought to originate from an error of development, when certain primordial germ cells fail to migrate properly.

Oogonia are formed in large numbers by mitosis early in fetal development from primordial germ cells.

A second cause of differentiation is illustrated by the way in which 'primordial germ cells' are formed in the fruitfly Drosophila.

Firstly just after fertilisation and secondly, in the developing primordial germ cells, the precursors to future gametes.

During the 6th to 8th week of female (XX) embryonic development, the primordial germ cells grow and begin to differentiate into oogonia.

In the primordial germ cells (PGC) there is a more extensive erasure of epigenetic information.

This store develops from primordial germ cells, a small population of cells that differentiate from other cell lineages in very early embryonic life.

During this time he published research on vibration sense, patent ductus arteriosus, paroxysmal nodal tachycardia, and primordial germ cells.

The testes begin as an immigration of primordial germ cells into testicular cords along the genital ridge in the abdomen of the early embryo.

In mammals, a few cells of the early embryo are induced by signals of neighboring cells to become primordial germ cells.

Spermatogenesis is the process by which male primordial germ cells called spermatogonia undergo meiosis, and produce a number of cells termed spermatozoa.

Oct-3/4 is expressed in primordial germ cells, unfertilized oocytes and in the inner cell mass and may play a role in early developmental decisions (47).

In the blastocyst of the mammalian embryo, primordial germ cells arise from proximal epiblasts under the influence of extra-embryonic signals.
