A microchip for metastasis
Nearly 70 percent of patients with advanced breast cancer experience skeletal metastasis, in which cancer cells migrate from a primary tumor into bone—a painful development that can cause fractures and ...
Researchers gain fuller picture of cell protein reactions
Over the past decade, advances in genetic mapping tools have provided great insight into how DNA influences cell behavior. But genetics is only half the equation; much of cells' behavior is the result of post-transcriptional ...
A bio patch that can regrow bone
Researchers at the University of Iowa have created a bio patch to regenerate missing or damaged bone by putting DNA into a nano-sized particle that delivers bone-producing instructions directly into cells.
Targeting cancer's 'queen bees' with better tissue modeling
In many types of cancer, standard chemotherapy cures only a fraction of patients. Treatments are often too toxic to normal cells and they fail to selectively kill cancer's stem cells, which can survive treatment ...
New nanotube surface promises dental implants that heal faster and fight infection
A brighter, better, longer-lasting dental implant may soon be on its way to your dentist's office.
Signal gradients in 3-D guide stem cell behavior
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.
New coating may help joint replacements bond better with bone
Broken bones and joint replacements may someday heal faster, thanks to an unusual coating for medical implants under development at The Ohio State University.
Scientists unable to find evidence of 'embryonic-like' cells in marrow of adult mice
Research on human embryonic stem cells has been a political and religious lightning rod for more than a decade.
Keeping stem cells strong: Biologists show that an RNA molecule protects stem cells during inflammation
When infections occur in the body, stem cells in the blood often jump into action by multiplying and differentiating into mature immune cells that can fight off illness. But repeated infections and inflammation ...
Researchers show stem cell fate depends on 'grip'
The field of regenerative medicine holds great promise, propelled by greater understanding of how stem cells differentiate themselves into many of the body's different cell types. But clinical applications ...
Research provides key insight into how cells fuse
Researchers at Johns Hopkins have established a high-efficiency cell-cell fusion system, providing a new model to study how fusion works. The scientists showed that fusion between two cells is not equal and ...
Stem cell breakthrough could lead to new bone repair therapies on nanoscale surfaces
Scientists at the University of Southampton have created a new method to generate bone cells which could lead to revolutionary bone repair therapies for people with bone fractures or those who need hip replacement surgery ...
Implants make light work of fixing broken bones
Artificial bone, created using stem cells and a new lightweight plastic, could soon be used to heal shattered limbs.
Whole-genome sequencing of the elephant shark offers insights into bone disease and immunity in humans
Sequencing the genomes of vertebrates can provide scientists with valuable clues about the evolution of the human genome. By analyzing and comparing different genomes, researchers can pinpoint variations ...
