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 ...
Immune cells regulate blood stem cells
Researchers in Bern, Germany, have discovered that, during a viral infection, immune cells control the blood stem cells in the bone marrow and therefore also the body's own defences. The findings could allow ...
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 ...
3D cell culture set for space: New technology to grow bone cells on International Space Station
Many people dream of blasting off into space and scientists are no different. But until space tourism becomes an affordable reality, surely the next best thing is to see your work go into orbit.
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 ...
Improving the performance of titanium implants by bioactive composite coatings
Researchers in Japan and China tested a novel urease fabrication process for coating titanium implants with bioactive CaP/gelatin composites. Published in Science and Technology of Advanced Materials, the re ...
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.
Evidence that disproves a long-standing assumption about fish development gives insight into evolution of skeletons
A Singapore-based research team has used fluorescent labeling of embryonic cell populations to pinpoint the origin of scales and fins in modern-day fish. These tissues are evolutionary relics of the first ...
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.
New scaffold reference material for tissue engineering research
The National Institute of Standards and Technology (NIST) has issued a new reference material—a sort of standardized sample—of cellular scaffolds for use in tissue engineering research.
