It is well-known that the risks of breast cancer increase dramatically for women over the age of 50, but what takes place at the cellular level to cause this increase has been a mystery. Some answers and the possibility of preventative measures in the future are provided in a new study by researchers at the U.S. Department of Energy (DOE)´s Lawrence Berkeley National Laboratory (Berkeley Lab). Mark LaBarge, a cell and molecular biologist in Berkeley Lab´s Life Sciences Division,...

Brown researchers have discovered mechanical properties of stem cells can foretell what they will become To become better healers, tissue engineering need a timely and reliable way to obtain enough raw materials: cells that either already are or can become the tissue they need to build. In a new study, Brown University biomedical engineers show that the stiffness, viscosity, and other mechanical properties of adult stem cells derived from fat, such as liposuction waste, can predict whether...

Cell surface protein blows potent cells' cover; targeted drug works in preclinical tests Breast cancer stem cells wear a cell surface protein that is part nametag and part bull's eye, identifying them as potent tumor-generating cells and flagging their vulnerability to a drug, researchers at The University of Texas MD Anderson Cancer Center report online in Journal of Clinical Investigation. "We've discovered a single marker for breast cancer stem cells and also found that it's...

Some cell types control continued tumor growth, others prepare the way for metastasis A study from Massachusetts General Hospital (MGH) researchers suggests that specific populations of tumor cells have different roles in the process by which tumors make new copies of themselves and grow. In their report in the May 15 issue of Cancer Cell, researchers identify a tumor-propagating cell required for the growth of a pediatric muscle tumor in a zebrafish model and also show that another,...

New research findings show that embryonic stem cells unable to fully compact the DNA inside them cannot complete their primary task: differentiation into specific cell types that give rise to the various types of tissues and structures in the body. Researchers from the Georgia Institute of Technology and Emory University found that chromatin compaction is required for proper embryonic stem cell differentiation to occur. Chromatin, which is composed of histone proteins and DNA, packages DNA...

Connie K. Ho for RedOrbit.com A new study by researchers at the University of California, Los Angeles (UCLA) has discovered two adult stem cell-like subpopulations in adult human skin. The findings allow for further research to be done in the area of personalized medicine and patient-specific cellular therapies. The study, using technology from Fibrocell Science, allowed the researchers to identify and confirm two types of cells in human skin cell cultures; the possible source of...

Results suggest researchers implement careful quality control A team led by scientists at The Scripps Research Institute and the University of California (UC) San Diego has discovered a new type of dynamic change in human stem cells. Last year, this team reported recurrent changes in the genomes of human pluripotent stem cells as they are expanded in culture. The current report, which appears in the May 4, 2012 issue of the journal Cell Stem Cell, shows that these cells can also change...

Berkeley Lab scientists demonstrate the promise of synchrotron infrared spectroscopy of living cells for medical applications Knowing how a living cell works means knowing how the chemistry inside the cell changes as the functions of the cell change. Protein phosphorylation, for example, controls everything from cell proliferation to differentiation to metabolism to signaling, and even programmed cell death (apoptosis), in cells from bacteria to humans. It´s a chemical process that...

Findings offer new insights into neurologic development and regenerative therapies for neurologic disease Researchers at Columbia University Medical Center (CUMC) have identified a molecular pathway that controls the retention and release of the brain's stem cells. The discovery offers new insights into normal and abnormal neurologic development and could eventually lead to regenerative therapies for neurologic disease and injury. The findings, from a collaborative effort of the...

In spite of considerable research efforts around the world, we still do not know the determining factors that confer stem cells their main particular features: capacity to self-renew and to divide and proliferate. The scientist Jordi Casanova, head of the “Morphogenesis in Drosophila” lab at IRB Barcelona and CSIC research professor, proposes in an article in the journal Embo Reports that we may be working from an incorrect angle. Casanova´s notion is that stem cells emerge...


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.
