1
The primordial germ is not poetical, but dissertational.
2
Is not every stage, from the primordial germ onward, and the whole sequence of stages, rigidly orthogenetic?
3
The theory that all plants and animals have descended from one primordial germ, is staggering to the mind.
4
Thus, we predicted that there is a mechanism that represses primordial germ cell-related gene expression in embryonic stem cells.
5
Instead, Nanog is transiently required for the specification of the naive pluripotent epiblast and development of primordial germ cells.
6
With the first primordial germ?
7
Early specification events do not seem to be affected, but the primordial germ cells fail to migrate dorsally and eventually disappear.
8
Inhibition of XDead end translation in Xenopus embryos results in a loss of primordial germ cells at tadpole stages of development.
9
They tell us that 3,000,000 species of plants and animals developed from one primordial germ, in 60,000,000 years.
10
Background: POU5F1 expression is required to maintain stem cell pluripotency and for primordial germ cells to retain proliferative capability in embryonic development.
11
Embryonic stem cells and primordial germ cells (PGCs) express many pluripotency-associated genes, but embryonic stem cells do not normally undergo conversion into primordial germ cells.
12
He assumes, also, the existence of life in the form of one or more primordial germs.
13
Primordial germ cells eventually migrate and differentiate into germ cells in the gonads, where they settle and rapidly proliferate.
14
Primordial germ cells (PGC) from early embryos are applicable to various kinds of research, including the production of transgenic animals.
15
"And the cell by nutrition evolved primordial germ, and germ devolved protogene, and protogene begat eozoon and eozoon begat monad and monad begot animalcule..."
