Ancient Immune Cells In Lampreys Similar To Ours, But More Complex
2013-08-13 08:06:38

April Flowers for redOrbit.com - Your Universe Online When biologists study lampreys, they are able to envision the evolutionary past because these jawless specimens represent an early offshoot to the evolutionary tree, before sharks and fish. They have an inconspicuous appearance, but a sophisticated immune system with three types of white blood cells that resemble our B and T cells. A new study from Emory University School of Medicine and the Max Planck Institute of Immunology and...

Stowers investigators show that rules governing expression of developmental genes in mouse embryonic stem cells are more nuanced than anticipated A decade ago, gene expression seemed so straightforward: genes were either switched on or off. Not both. Then in 2006, a blockbuster finding reported that developmentally regulated genes in mouse embryonic stem cells can have marks associated with both active and repressed genes, and that such genes, which were referred to as "bivalently marked...

Efficient Model For Generating Human iPSCs Developed By UC San Diego Researchers
2013-08-02 07:55:05

University of California - San Diego Approach has potential to simplify generation of iPSCs for use in human stem cell therapies Researchers at the University of California, San Diego School of Medicine report a simple, easily reproducible RNA-based method of generating human induced pluripotent stem cells (iPSCs) in the August 1 edition of Cell Stem Cell. Their approach has broad applicability for the successful production of iPSCs for use in human stem cell studies and eventual cell...

And extend survival in mice with hepatic failure Researchers have generated functional hepatocytes from human stem cells, transplanted them into mice with acute liver injury, and shown the ability of these stem-cell derived human liver cells to function normally and increase survival of the treated animals. This promising advance in the development of cell-based therapies to treat liver failure resulting from injury or disease relied on the development of scalable, reproducible methods to...

A recent study published in the Neural Regeneration Research (Vol. 8, No. 17, 2013) injected recombinant lentivirus carrying enhanced green fluorescent protein and the target gene Atoh1 into the cochlea of normal rats using a postauricular approach via the round window membrane. After 30 days, recombinant lentivirus was shown to have no impact on the hair cell numbers and auditory functions, infect hair and supporting cells, and promote supporting cells to transdifferentiate into hair cells....

Biologists at the California Institute of Technology (Caltech) have worked out the details of a mechanism that leads undifferentiated blood stem cells to become macrophages—immune cells that attack bacteria and other foreign pathogens. The process involves an unexpected cycle in which cell division slows, leading to an increased accumulation of a particular regulatory protein that in turn slows cell division further. The finding provides new insight into how stem cells are...

Nuanced Approach To Creating Stem Cells
2013-07-19 10:25:21

Brett Smith for redOrbit.com - Your Universe Online Stem cell studies are producing some of the most promising research results for replacing or regenerating damaged tissue, and a new study from a team of Spanish and American scientists has described a more flexible approach to creating the valuable cells. Nobel Prize laureate Shinya Yamanaka developed the initial formula for developing induced pluripotent stem cells (iPSCs), or stem cells created by reverse-engineering...

Adult Human Cells Used To Create Long-Lived Blood Vessels
2013-07-16 09:20:13

redOrbit Staff & Wire Reports - Your Universe Online Massachusetts General Hospital (MGH) researchers have managed to create long-lasting blood vessels from reprogrammed human induced pluripotent stem cells (iPSCs), This groundbreaking research is published in the latest issue of the Proceedings of the National Academy of Sciences (PNAS) Early Edition. Using vascular precursor cells derived from iPSCs, reprogrammed adult cells that have several of the same characteristics of...


Word of the Day
omadhaun
  • A fool; a simpleton: a term of abuse common in Ireland and to a less extent in the Gaelic-speaking parts of Scotland.
This word is partly Irish in origin.
