Novel stem cell-containing bio-ink allows 3D printing of complex tissues for surgical implants

Scientists at the University of Bristol have developed a new kind of bio-ink, which could eventually allow the production of complex tissues for surgical implants.

Metal ions released by implant wear can damage progenitors of bone-forming cells

In metal-on-metal pairings, both the shell and head of an implant consist of a cobalt-chromium-molybdenum alloy. The release of metal ions into the body has been reported as a result of implant wear. Bone loss (osteolysis) was observed in many cases.

Sostdc1 gene may play vital role in fracture healing process

New identification of a gene involved in the fracture healing process could lead to the development of new therapeutic treatments for difficult-to-heal injuries.

New mice study unveils mystery of why chronic stress, depression can lead to bone loss

A new study has helped to unveil the mystery of why chronic stress and depression can lead to bone loss and increase the risk of fractures.

Development of atherosclerosis can increase osteoporosis risk

Patients with atherosclerosis—the buildup of cholesterol and fat in arteries—are at a higher risk of osteoporosis. A new study published in the American Journal of Physiology—Endocrinology and Metabolism shows how the development of atherosclerosis encourages the loss of bone density.

Psoriasis patients experience widespread bone loss

Researchers from the Genes, Development and Disease Group, headed by Erwin Wagner at the Spanish National Cancer Research Centre have discovered that psoriasis patients experience a widespread bone loss as a result of the disease.

Study provides insights into cellular mechanisms that may contribute to new osteoarthritis treatments

Researchers show that the protein CCN4 positively regulates the generation of cartilage matrix, which are depleted in osteoarthritis.

Low-sodium intake has little impact on bone health in postmenopausal women

A low-salt diet does not necessarily translate to stronger bones in postmenopausal women, physician-scientists report.

Scientific breakthrough could contribute to early diagnosis of osteoporosis, Alzheimer's

Scientists from the University of Granada have developed a new fluorescent dye capable of detecting, in a single test lasting 20 minutes, the presence of phosphate and biothiol inside living cells. This scientific breakthrough could contribute significantly to the early diagnosis of diseases such as osteoporosis, Alzheimer's, type 2 diabetes, and prostate cancer, since abnormal levels of both substances are associated with these diseases.

Research points to potential use of radiotherapy in treating systemic cancer

An international team of researchers lead by the University of Granada has proven that mesenchymal stem cells (MSC) may be used as enhancer agents of local and systemic effects of radiotherapy, that is to say, those which affect the irradiated tumour and tumour cells located at a certain distance of the irradiated ones.

Research shows how scientists altered stem cells, triggered bone growth

Imagine you have a bone fracture or a hip replacement, and you need bone to form, but you heal slowly - a common fact of life for older people. Instead of forming bone, you could form fat. Researchers at the University of North Carolina School of Medicine may have found a way to tip the scale in favor of bone formation. They used cytochalasin D, a naturally occurring substance found in mold, as a proxy to alter gene expression in the nuclei of mesenchymal stem cells to force them to become osteoblasts (bone cells).

Study demonstrates potential of FCPCs as new source for cartilage regeneration

The self-repair of injured cartilage is difficult for several reasons, foremost of which is the lack of blood supply to the tissue. Therapeutic efforts aimed at cartilage repair are often not optimal. Surgical repair techniques often lead to the formation of fibrocartilage, which is weaker and less durable. Although cell transplantation aimed at cartilage repair has been carried out using mesenchymal stem cells (MSCs), varying outcomes have resulted, despite the propensity of MSCs to proliferate and differentiate.

$Common Alzheimer's disease drug increases bone density, reduces fracture risks$

Common Alzheimer's disease drug increases bone density, reduces fracture risks

The most common drug used to treat Alzheimer's disease increases bone mass in mice, according to one of the first research articles published in the new open access journal Heliyon. The authors of the study, from Saitama Medical University in Japan, say this means the drug could also be used to treat bone loss diseases like osteoporosis and periodontitis, following further clinical research.

Transplanting mesenchymal stromal cells derived from amniotic membranes can benefit eye diseases

A team of researchers in South Korea has successfully transplanted mesenchymal stromal cells (MSCs) derived from human amniotic membranes of the placenta (AMSCs) into laboratory mice modeled with oxygen-induced retinopathy (a murine model used to mimic eye disease).

Cell transplantation researchers successfully treat laboratory rats modeled with severe burns

Cell transplantation researchers have successfully used bone marrow-derived mesenchymal stromal cells (MSCs) to treat a variety of diseases and conditions. Now, using injections of MSCs, a research team in Brazil has successfully treated laboratory rats modeled with severe burns.

New article shows taxonomic classification of rare genetic bone disorders based on metabolic phenotypes

An International Osteoporosis Foundation Working Group on Skeletal Rare Diseases has published a new classification of rare genetic metabolic bone disorders (RGMBDs) according to their metabolic pathogenesis.

Scientists report that mouse with weak bones appears to have strong metabolism

One mouse with weak bones appears to have a strong metabolism, even on a high-fat diet, scientists report. While weaker bones are clearly not a good thing, scientists suspect that, somewhere in the conversation between the genetically engineered mouse's skeleton and the rest of its body, there may be an answer that helps obese individuals avoid some of the worst ravages of this health epidemic.

New therapy for osteoporosis may be in the pipeline

Researchers from The Scripps Research Institute (TSRI), Florida, have reported a novel therapeutic approach that could promote the formation of new bone cells in people suffering from bone loss.

Gold nanoparticles with functional surfaces regulate osteogenic differentiation of stem cells

Tissue Regeneration Materials Unit (Guoping Chen, Unit Director) at the International Center for Materials Nanoarchitectonics (MANA) (Masakazu Aono, Director General, MANA), NIMS (Sukekatsu Ushioda, President) successfully developed gold nanoparticles that have functional surfaces and act on osteogenic differentiation of stem cells.

$Bone-marrow-derived MSCs can promote fracture healing$

Bone-marrow-derived MSCs can promote fracture healing

Mesenchymal stem cells (MSCs) have been transplanted to successfully treat a variety of diseases and conditions. The benefit of using MSCs is their ability to self-renew and differentiate into a variety of specialized cell types, such as osteoblasts (cells contributing to bone formation), chondrocytes (cartilage cells), adipocytes (fat cells), myocardiocytes (the muscle cells that make up the cardiac muscle), and neurons (nervous system cells).
