Dec 14 2018 Exercise has been touted to build bone mass, but exactly how it actually accomplishes this is a matter of debate. Now, researchers show that an exercise-induced hormone activates cells that are critical for bone remodeling in mice. A study appearing in the journal Cell on December 13 identifies a receptor for irisin, […]Continue Reading ...
Cancer-associated fibroblasts are derived from bone marrow cells called mesenchymal stromal cells, Tel Aviv University researchers say Tel Aviv University researchers have discovered that breast cancer tumors boost their growth by recruiting stromal cells that originate in bone marrow. While the recruitment of bone marrow-derived fibroblasts lowers the odds of surviving breast cancer, the study […]Continue Reading ...
For a child, recovering from a broken bone is typically a short-lived, albeit painful, convalescence. But for older adults, it can be a protracted and potentially life-threatening process. Finding ways to speed bone repair is a public health priority that could save both lives and health care expense. The Centers for Disease Control and Prevention […]Continue Reading ...
Credit: CC0 Public Domain A material based on a natural product of bones and citrus fruit, called citrate, provides the extra energy that stem cells need to form new bone tissue, according to a team of Penn State bioengineers. Their new understanding of the mechanism that allows citrate to aid in bone regeneration will help […]Continue Reading ...
Not all broken bones heal. But one scientist at the University of Arizona hopes to remedy that problem using a combination of 3D printing and adult stem cells. “Imagine an impact that causes half of a long bone to shatter so that it can’t be put back together – no current surgical treatment can ensure […]Continue Reading ...
Researchers from Chalmers University of Technology, Sweden, have discovered how our bones grow at an atomic level, showing how an unstructured mass orders itself into a perfectly arranged bone structure. The discovery offers new insights, which could yield improved new implants, as well as increasing our knowledge of bone diseases such as osteoporosis. The bones […]Continue Reading ...
WEDNESDAY, Nov. 7, 2018 — Among women who are under/normal weight, gestational weight gain (GWG) is associated with slightly increased bone measures in offspring at age 7 years, but there is no effect for overweight/obese mothers, according to a study published online Nov. 7 in the Journal of Bone and Mineral Research. Teresa Monjardino, M.P.H., […]Continue Reading ...
Peter Yang was napping on a tour bus in Alaska, when his wife gave him a nudge. “Hey, you oughta hear this,” she told him. They were on an eight-hour ride to Denali National Park and their guide was mid-spiel, describing the remarkable growth rate of deer antlers, a type of regenerative bone. Yang, PhD, […]Continue Reading ...
Women 55 and older have an increased risk of bone and muscle loss but therapy with the hormone Dehydroepiandrosterone (DHEA) may help prevent bone loss and increase muscle mass in older women, according to a new study led by Catherine M. Jankowski, PhD, FACSM, an exercise physiologist and associate professor at the University of Colorado […]Continue Reading ...
Credit: CC0 Public Domain Researchers from the Faculty of Chemical Technology, Kaunas University of Technology (KTU), Lithuania are developing an artificial bone that can be used to treat osteoarthritis. The bi-functional composite imitates the complex osteochondral structure of a joint, i.e. both cartilage and bone tissues. According to the World Health Organisation, around 10 percent […]Continue Reading ...
A material based on a natural product of bones and citrus fruit, called citrate, provides the extra energy that stem cells need to form new bone tissue, according to a team of Penn State bioengineers. Their new understanding of the mechanism that allows citrate to aid in bone regeneration will help the researchers develop slow-release, […]Continue Reading ...
The bones in our body grow through several stages, with atoms and molecules joining together, and those bigger groupings joining together in turn. One early stage in the growth process is when calcium phosphate molecules crystallise, which means that they transform from an amorphous mass into an ordered structure. Many stages of this transformation were […]Continue Reading ...
Uncovering a novel mechanism that promotes growth of breast cancer bone metastasis has revealed a potential Achilles’ heel for these cancer cells. Reported in the journal Cancer Cell, the study shows that interfering with this mechanism can reduce the risk of relapses in animal models. “Metastasis is the dissemination of cancer cells from the original […]Continue Reading ...
Researchers at the University of Michigan have made an important discovery about skeletal stem cells that could help scientists understand bone abnormalities and diseases that arise in some people. Image Credit: lmstockwork / Shutterstock Skeletal stem cells are of interest to researchers because they are thought to be able to heal bone injuries. However, they […]Continue Reading ...
A study has found that treatment-resistant hypertension may be associated with low-level accumulation of lead in the shin bone of men. Image Credit: Jiri Vaclavek / Shutterstock As reported in the Journal of the American Heart Association, Park and team tested lead levels in the blood, kneecaps and tibia of 475 men with hypertension, 97 […]Continue Reading ...
