Sentences with phrase «germ line stem»

Using this method, they tracked the tendency of the X and the Y chromosome copies to move to the daughter germ line stem cell or to the gonialblast.

Not exact matches

During the last decade, some researchers have claimed that primordial follicles in adult mouse ovaries turn over and that females use adult germ - line stem cells to constantly resupply the follicle pool and sustain ovulation.

Their research showed that primordial follicles are highly stable, and that germ - line stem cell activity can not be detected, even in response to the death of half the existing follicles.

This makes a certain kind of sense, since the stem cells in the paternal germ line undergo continuous cell division throughout a man's life, whereas a woman is born with all of the eggs she'll ever have.

Establishment of a human embryonic germ cell line and comparison with mouse and human embryonic stem cells.

Arantes - Oliveira N, Apfeld J, Dillin A, Kenyon C. Regulation of Lifespan by germ - line stem - cells in Caenorhabditis elegans.

Sophia Millonigg (Eckmann, MPG)-- «The translational activator complex GLD - 4 / GLS - 1 regulates germline stem cell self - renewal and differentiation in the adult C. elegans germ line» (2013)

My post-doctoral work on the identification of genes required for normal germ line development and fertility led to the discovery that the germ line is exquisitely sensitive to mutations in components of the mitotic spindle that have the potential to lead to aneuploidy — this sensitivity may also extend to embryonic and adult stem cells.

Embryonic stems cells often contribute to the germ line, resulting in the production of some sperm carrying the extra DNA.

Human Haploid Cells Differentiated from Meiotic Competent Clonal Germ Cell Lines That Originated from Embryonic Stem Cells.

The majority of gene - targeting experiments in mice are performed in 129Sv - derived embryonic stem (ES) cell lines, which are generally considered to be more reliable at colonizing the germ line than ES cells derived from other strains.

Advanced reproductive techniques such as artificial insemination, culturing of primordial germ cells for germ - line transmission, stem cell embryogenesis, and cloning offer an array of new ways to expand and even infuse lost and new genetic variability into at - risk wildlife populations.

His pioneering mouse embryonic stem (ES) cell work in the 1980s, demonstrating germ - line transmission and the great potential of ES cells to generate mice carrying mutations in endogenous genes, established milestones in a field that saw the award of the 2007 Nobel Prize in Physiology or Medicine to Mario Capecchi, Martin Evans, and Oliver Smithies.

The Perfect Host: a mouse host embryo facilitating more efficient germ line transmission of genetically modified embryonic stem cells.
