Five-year program will refine use of adult stem cells and novel biological sutures developed at WPI to heal damaged hearts. Worcester, MA (PRWEB) August 28, 2013 The National Institutes of Health (NIH) has awarded a five-year, $1.94 million grant to a biomedical research team at Worcester Polytechnic Institute (WPI) working at the forefront of cell therapies for healing cardiac muscle damaged by heart attack or chronic disease. Funded through the NIH's premiere Research Project Grant...

Work has important treatment implications In a scientific first, Harvard Stem Cell Institute scientists have successfully grown the cells that line the blood vessels—called vascular endothelial cells—from human induced pluripotent stem cells (iPSCs), revealing new details about how these cells function. Using a unique approach, the researchers induced the differentiation of specific cell types by generating mechanical forces on the surface of the iPSC-derived endothelium mimicking the...

A study investigating the function of the recently discovered enhancer RNA molecules may open new avenues for gene therapy. According to the study researchers, altering the production and function of these molecules could affect the expression of genes and, in consequence, possibly also the progression of various diseases. Published in the prestigious Molecular Cell on 8 August, the study was carried out in collaboration between the University of California, San Diego and the University of...

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

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...


Word of the Day
penuche
  • A fudgelike confection of brown sugar, cream or milk, and chopped nuts.
'Penuche' is a variant of 'panocha,' a coarse grade of sugar made in Mexico. 'Panocha' probably comes from the Spanish 'panoja, panocha,' ear of grain.
