In a world first, scientists from Cincinnati Children’s Hospital Medical Center have created functioning fetal intestinal tissue from pluripotent stem cells. It is now hoped that such lab-grown tissue could be used to research treatments for gastro-intestinal diseases, or for transplantation.  Read More

In what could be the first step towards same-sex couples having their own genetic children, reproductive scientists have produced male and female mice from two fathers using stem cell technology. The achievement of two-father offspring in a species of mammal could also be a step toward preserving endangered species, improving livestock breeds, and advancing human assisted reproductive technology (ART).  Read More

Stem cells, which have the ability to become various other types of cells, are at the heart of the burgeoning field of regenerative medicine – if a patient’s stem cells could be raised outside of their body, and their growth dictated, they could ultimately be used to grow replacement body parts that wouldn’t be rejected. It’s challenging, however, to create sufficient growing conditions in a petri dish. In order for stem cells to grow and differentiate within the body, they rely on chemical, mechanical and electrical cues. Although chemical cues have been combined with mechanical or electrical cues in lab settings, no one has so far been able to combine all three... at least, not until now.  Read More

Blood transfusions may one day come from blood produced from a patient's skin

A new technique that allows blood to be made directly from skin cells has been discovered. The pioneering approach by Canadian researchers uses human skin stem cells to create blood stem cells without an intermediate step that previously was thought necessary. It could be used for creating blood for surgery, or treating conditions like anemia using a patch of the patient's skin.  Read More

Stem cells harvested from mice have been used to reattach molars in rats

Researchers from the University of Illinois at Chicago have successfully used stem cells to reattach molars to tooth sockets within lab rats’ mouths. The stem cells were obtained from the periodontal ligament of molars extracted from mice, expanded in an incubator, and then seeded onto barren rat molars. This could have great implications for humans who lose teeth due to gum disease in the future... and for all those toothless old rats out there.  Read More

Researching liver disorders is extremely difficult because liver cells (hepatocytes) cannot be grown in the laboratory. However, researchers at the University of Cambridge have now managed to create diseased liver cells from a small sample of human skin. The research shows that stem cells can be used to model a diverse range of inherited disorders and paves the way for new liver disease research and possible cell-based therapy.  Read More

Rows of human embryonic stem cells, grown on the new surface

Stem cells have been touted as the potential key to treating ailments ranging from Parkinson’s disease and multiple sclerosis to spinal cord injuries, to name just a few. That’s because they can be made into any type of cell that’s needed - they’re essentially the plasticine of the cell world. The problem that scientists have encountered is the difficulty in growing them. For one thing, it’s hard to grow enough of them to perform large-scale experiments. For another, most of the materials upon which the stem cells are grown contain cells or proteins from mouse embryos, which stimulate cell growth but would probably also cause an immune reaction if injected into a human recipient. Researchers from the Massachusetts Institute of Technology (MIT), however, have just announced the creation of a new growing surface that does away with both of these limitations.  Read More

A new breakthrough in cell regeneration could lead to the repair of damaged hearts (Image ...

Heart disease remains one the biggest killers in the Western world. When a heart attack or heart failure occurs, permanent damage often results, destroying live cells and leaving the patient with irreversible scarring. Now scientists at the Gladstone Institute of Cardiovascular Disease (GICD) have discovered a new technique to create healthy beating heart cells from structural cells, opening up the possibility of regenerating damaged hearts.  Read More

Although medical advances over recent years have seen the majority of people surviving heart attacks, the damage done to the heart muscle is irreversible. As a result, most patients eventually succumb to congestive heart failure, the most common cause of death in developed countries. Stem cells offer hope for achieving what the human body can’t do: mending broken hearts. Now researchers have built a scaffold that supports the growth and integration of stem cell-derived cardiac muscles cells. The scaffold supports the growth of cardiac cells in the lab and encourages blood vessel growth in living animals.  Read More

A combination of nanotechnology and adult stem cells has been shown to destroy arterial plaque (atherosclerosis) in the heart of pigs. Pigs that received stem cells also showed signs of new blood vessel growth and restoration of artery function according to the study reported at the American Heart Association's Basic Cardiovascular Sciences 2010 Scientific Sessions – Technological and Conceptual Advances in Cardiovascular Disease.  Read More
