On the origin of the human germline.
In mice, primordial germ cells (PGCs), the precursors of eggs and sperm, originate from pregastrulation postimplantation embryos. By contrast, the origin of human PGCs (hPGCs) has been less clear and has been difficult to study...

The unfolding body plan of primate embryos in culture.
Improved culture of non-human primate embryos reveals the establishment of the crucial framework for subsequent development of bodily tissues and the germline in fetuses, bringing us closer to comprehending the elusive...

Pluripotent cells have the potential to differentiate into any cell type in the body. Their isolation and propagation from mouse embryos was pivotal for advances in understanding human development and disease.
Developmental Competence for Primordial Germ Cell Fate.
During mammalian embryonic development, the trophectoderm and primitive endoderm give rise to extraembryonic tissues, while the epiblast differentiates into all somatic lineages and the germline. Remarkably, only a few classes...
The fragilis interferon-inducible gene family of transmembrane proteins is associated with germ cell specification in mice.
BACKGROUND: Specification of primordial germ cells in mice depends on instructive signalling events, which act first to confer germ cell competence on epiblast cells, and second, to impose a germ cell fate upon competent...
Conserved features of non-primate bilaminar disc embryos and the germline.
Post-implantation embryo development commences with a bilaminar disc in most mammals, including humans. Whereas access to early human embryos is limited and subject to greater ethical scrutiny, studies on non-primate embryos...

Specification and epigenetic programming of the human germ line.
Primordial germ cells (PGCs), the precursors of sperm and eggs, are established in perigastrulation-stage embryos in mammals. Signals from extra-embryonic tissues induce a unique gene regulatory network in germline-competent...
Germ cell specification and pluripotency in mammals
Germ cells are unique cell types that generate a totipotent zygote upon fertilization, giving rise to the next generation in mammals and many other multicellular organisms. How germ cells acquire this ability has been of...
Testing the role of SOX15 in human primordial germ cell fate.
Background: Potentially novel regulators of early human germline development have been identified recently, including SOX15 and SOX17, both of which show specific expression in human primordial germ cells. SOX17 is now known to...

PRDM14 is a crucial regulator of mouse primordial germ cells (mPGCs), epigenetic reprogramming and pluripotency, but its role in the evolutionarily divergent regulatory network of human PGCs (hPGCs) remains unclear. Besides, a...
