Generating new cardiac muscle from human embryonic stem cells (hESCs) and/or induced pluripotent stem cells (iPSC) could fulfill the demand for therapeutic applications and drug testing. The production of a similar population of these cells remains a major limitation, but in a study just published in STEM CELLS Translational Medicine, researchers now believe they have found a way to do this. Durham, NC (PRWEB) December 09, 2013 Generating new cardiac muscle from human embryonic stem cells...

Researchers Discover How To Change Cell Types By Flipping A Single Switch
2013-12-04 13:05:09

University of California - Santa Barbara With few exceptions, cells don't change type once they have become specialized — a heart cell, for example, won't suddenly become a brain cell. However, new findings by researchers at UC Santa Barbara have identified a method for changing one cell type into another in a process called forced transdifferentiation. Their work appears today in the journal Development. With C. elegans as the animal model, lead author Misty Riddle, a Ph.D. student...

The electrophysiological properties of potassium ion channels are regarded as a basic index for determining the functional differentiation of neural stem cells. A recent study published in the Neural Regeneration Research (Vol. 8, No. 28, 2013) showed that the proliferating neural stem cells selected were capable of differentiating into neural cells, and the differentiation process was accompanied by the expression of potassium currents. After 2 weeks of differentiation and development, the...

The blood stem cells that live in bone marrow are at the top of a complex family tree. Such stem cells split and divide down various pathways that ultimately produce red cells, white cells and platelets. These “daughter” cells must be produced at a rate of about one million per second to constantly replenish the body’s blood supply. Researchers have long wondered what allows these stem cells to persist for decades, when their progeny last for days, weeks or months before they need to...

Scientists at Karolinska Institutet in Sweden have discovered that two separate species of salamander differ in the way their muscles grow back in lost body parts. Their findings on the species-specific solutions, published in the scientific periodical Cell Stem Cell, demonstrate there is more than one mechanism of tissue regeneration. To carry out their study, the scientists labelled different cell types in two species of salamander in order to ascertain what kinds of cell give rise to...

Salk Institute Findings may lead to much-needed therapies for kidney disease Diseases affecting the kidneys represent a major and unsolved health issue worldwide. The kidneys rarely recover function once they are damaged by disease, highlighting the urgent need for better knowledge of kidney development and physiology. Now, a team of researchers led by scientists at the Salk Institute for Biological Studies has developed a novel platform to study kidney diseases, opening new avenues...

Kidney repair may not require stem cells Harvard Stem Cell Institute (HSCI) researchers have a new model for how the kidney repairs itself, a model that adds to a growing body of evidence that mature cells are far more plastic than had previously been imagined. After injury, mature kidney cells dedifferentiate into more primordial versions of themselves, and then differentiate into the cell types needing replacement in the damaged tissue. This finding conflicts with a previously held...

redOrbit Staff & Wire Reports - Your Universe Online For the first time, scientists from the Salk Institute for Biological Studies have taken stem cells from chimpanzees and bonobos and turned them into induced pluripotent stem cells (iPSCs), and their work has helped to highlight some of the differences between humans and non-human primates. This type of cell, which has the ability to form any other type of cell or tissue in the body, can be used to model diseases that would...

Technique has potential use in regenerative medicine and drug development University of Toronto researchers have developed a method that can rapidly screen human stem cells and better control what they will turn into. The technology could have potential use in regenerative medicine and drug development. Findings are published in this week's issue of the journal Nature Methods. "The work allows for a better understanding of how to turn stem cells into clinically useful cell types more...

In a feat of modern-day alchemy with huge potential for regenerative medicine, Stanford University School of Medicine scientists have developed a fast, efficient way to turn cells extracted from routine liposuction into liver cells. The advance is described in a study to be published Oct. 21 in Cell Transplantation. The scientists performed their experiments in mice, but the adipose stem cells they used came from human liposuction aspirates and became human, liver-like cells that...
