More than 1,125,000 men around the world have the inherited bleeding disorder of hemophilia, and 418,000 of those have a severe version of the mostly undiagnosed disease, says a new study led by McMaster University researchers. This is three times what was previously known. Only 400,000 people globally were estimated to have the disorder which […]
The expression of many genes that have previously been associated with autism is abnormal also in violent psychopathy, a new study shows. The researchers used stem cell technology to analyse the expression of genes and proteins in the brain cells of psychopathic violent offenders. Published in Molecular Psychiatry, the findings may open up new avenues […]
Pluripotent cells can give rise to all cells of the body, a power that researchers are eager to control because it opens the door to regenerative medicine and organ culture for transplants. But pluripotency is still a black box for science, controlled by unknown genetic (expression of genes) and epigenetic signals (biochemical marks that control […]
Semiconducting polymers, very large chain-like molecules made from repeating sub-units, are increasingly drawing the attention of researchers because of their potential applications in organic electronic devices. Like most semiconducting materials, semiconducting polymers can be classified as p-type or n-type according to their conducting properties. Although p-type semiconducting polymers have seen dramatic improvements thanks to recent […]
One of the most exciting advancements in stem cell research has been the development of organoid systems, which are organ-like three-dimensional structures that mimic their corresponding organ in vivo. In this important review in Digestive and Liver Disease, published by Elsevier, scientists highlight some of the established and exciting novel uses for organoids or “organs […]
A new study conducted at the University of Copenhagen challenges traditional knowledge of stem cell development. The study reveals that the destiny of intestinal cells is not predetermined, but instead determined by the cells’ surroundings. The findings may make it easier to manipulate stem cells for stem cell therapy. Results have just been published in […]
Induced pluripotent stem (iPS) cells are among the most important tools in modern biomedical research, leading to new and promising possibilities in precision medicine. To create them requires transforming a cell of one type, such as skin, into something of a blank slate, so it has the potential to become virtually any other kind of […]
How do bones heal, and how could they heal better? The answer to these questions may lie in a newly discovered population of “messenger” cells, according to a recent USC Stem Cell study published in the journal eLife. “With nearly half a million patients in the U.S experiencing failed bone repair every year, stimulating these […]
Here’s something to chew on: One in four people are impacted by defects of the temporomandibular — or jaw — joint. Despite the pervasiveness of this affliction, treatments are lacking, and many sufferers resort to palliative measures to cope with the pain and debilitation it causes. “The TMJ is central to chewing, talking and so […]
CRISPR/Cas enables the targeted deactivation of genes by cutting DNA at pre-determined sites. This is accomplished by providing the Cas enzyme with a genetic zip code. Using an entire library of zip codes, it is then possible to simultaneously probe multiple sites within the genome, for example to determine which genes are essential for cancer […]
