New research has shown that the stomach naturally produces more stem cells than previously realized, likely for repair of injuries from infections, digestive fluids and the foods we eat. Stem cells can make multiple kinds of specialized cells, and scientists have been working for years to use that ability to repair injuries throughout the body. But causing specialized adult cells to revert to stem cells and work on repairs has been challenging. Scientists from Washington University...

Stem Cell Breakthrough Could Aid In Future Transplant Therapies

University of Cambridge A new method for creating stem cells for the human liver and pancreas, which could enable both cell types to be grown in sufficient quantities for clinical use, has been developed by scientists. Using the technique, researchers have for the first time been able to grow a pure, self-renewing population of stem cells specific to the human foregut, the upper section of the human digestive system. These so-called "Foregut stem cells" could then be developed...

This press release is in support of a presentation by Dr. Daniel van den Hove on Sunday Oct. 6 at the 26th ECNP Congress in Barcelona, Spain Increasing evidence suggests that epigenetic regulation is associated with the pathogenesis of Alzheimer's disease (AD) and targeting it may one day lead to novel diagnostic and therapeutic strategies, research suggests. Scientists at The School for Mental Health and Neuroscience at Maastricht University, the Netherlands, have been performing...

The ability to make induced pluripotent stem cells (iPSCs) from mature cells in the body holds great potential for improved drug screening, disease modeling, and medical treatments for numerous conditions. Establishing well-characterized panels of iPSC lines that reflect the diversity of the human population and include samples from patients with a wide range of diseases will be key to tapping into the potential of iPSCs. In the October 3 issue of the Cell Press journal Cell Stem Cell,...

A team at IRB Barcelona identifies an essential protein for embryonic viability during the first cell divisions in the fly Drosophila. This protein, called dBigH1, which is a variant of histone 1, could also be associated with fertility issues. A zygote is the first cell of a new individual that comes about as the result of the fusion of an ovule with a spermatozoid. The DNA of the zygote holds all the information required to generate an adult organism. However, in the first stages of...

Induced pluripotent stem cells (iPSCs) taken from a patient hold great therapeutic potential for many diseases. However, studies in rodents have suggested that the body may mount an immune response and destroy cells derived from iPSCs. New research in monkeys refutes these findings, suggesting that in primates like us, such cells will not be rejected by the immune system. In the paper, publishing September 26 in the ISSCR's journal Stem Cell Reports, published by Cell Press, iPSCs from...

Comparing species, researchers at Harvard SEAS and Harvard Medical School investigate a process they dub “villification” “You are not just a ball of cells,” says Clifford Tabin, George Jacob and Jacqueline Hazel Leder Professor of Genetics at Harvard Medical School (HMS). The way cells organize within the human body allows us all to function the way we do, but a couple of Harvard professors are concerned as much with that developmental process as with the end result. Tabin...

A new method for analyzing gene expression in single cells opens a window into tumors and other tissues A team of researchers affiliated with Ludwig Cancer Research and the Karolinska Institutet in Sweden report in the current issue of Nature Methods a dramatically improved technique for analyzing the genes expressed within a single cell -- a capability of relevance to everything from basic research to future cancer diagnostics. "There are cells in tumors and in healthy tissues that are...

System can help discern recipes for tissue and organ repair and replacements Scientists know that physical and biochemical signals can guide cells to make, for example, muscle, blood vessels or bone. But the exact recipes to produce the desired tissues have proved elusive. Now, researchers at Case Western Reserve University have taken a step toward identifying that mix by developing an easy and versatile way of forming physical and biochemical gradients in three dimensions....


Word of the Day
cenobite
  • One of a religious order living in a convent or in community; a monk: opposed to anchoret or hermit (one who lives in solitude).
  • A social bee.
This word comes from the Latin 'coenobium,' convent, which comes from the Greek 'koinobios,' living in community.
