Dramatic advances in the fields of biochemistry, cell and molecular biology, genetics, biomedical engineering and materials science have given rise to the remarkable new cross-disciplinary field of tissue engineering. Tissue engineering uses synthetic or naturally derived, engineered biomaterials to replace damaged or defective tissues, such as bone, skin, and even organs.
Cancer that has spread, or metastasized, from its original site to other tissues and organs in the body is a leading cause of cancer death.
University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.
Group of researchers at Kaunas University of Technology, Lithuania are developing new generation sponge-like wound dressings with hyaluronic acid. Antimicrobial, antioxidant, anti-inflammatory wound dressings stimulate tissue regeneration and can be especially efficient in treating deep wounds that are difficult to heal.
Kyle Quinn, assistant professor of biomedical engineering at the University of Arkansas, has published a review highlighting recent advances in autofluorescence imaging and discussing its role in evaluating cell metabolism.
A new study of the effects of spaceflight on the development of heart cells identified changes in calcium signaling that could be used to develop stem cell-based therapies for cardiac repair.
A penetrating injury from shrapnel is a serious obstacle in overcoming battlefield wounds that can ultimately lead to death.Given the high mortality rates due to hemorrhaging, there is an unmet need to quickly self-administer materials that prevent fatality due to excessive blood loss.
Lower temperatures can activate the body's 'good' fat formation at a cellular level, a new study led by academics at The University of Nottingham has found.
The heart is the first organ to develop in the womb and the first cause of concern for many parents.
The first direct comparison of in vitro and in vivo screening techniques for identifying nanoparticles that may be used to transport therapeutic molecules into cells shows that testing in lab dishes isn't much help in predicting which nanoparticles will successfully enter the cells of living animals.
Biophysicists from MIPT have studied the structure of a nanofibrous scaffold, as well as its interaction with rat cardiac cells.
Michael Nelson, assistant professor of kinesiology at The University of Texas at Arlington, has received a new five-year, $3.3 million grant from the National Institutes of Health to study the link between fat storage in the heart and cardiovascular disease, as well as the influence of gender on the development of cardiac dysfunction.
The burst of cells forming cartilage is associated with mineralization during the early stages of bone formation, and nanofragments of the cell membranes can act as nucleation sites for amorphous calcium phosphate, as reported in two studies just published in Integrative Biology and ASC Biomaterials Science and Engineering.
Using a new technique they call 'in-air microfluidics', University of Twente scientists succeed in printing 3D structures with living cells.
In breakthrough colon cancer research, scientists at Christiana Care Health System's Center for Translational Cancer Research of the Helen F. Graham Cancer Center & Research Institute have discovered that over-expression of HOXA4 and HOXA9 genes in colon cancer stem cells promotes cell replication and contributes to the overpopulation of stem cells that drives colon cancer development.
Researchers at the Institute of Industrial Science, the University of Tokyo, CNRS and INSERM, report a new organ-on-a-chip technology for the study of blood vessel formation and drugs targeting this event.
Gene editing is one of the hottest topics in cancer research. A Chinese research team has now developed a gold-nanoparticle-based multifunctional vehicle to transport the "gene scissors" to the tumor cell genome.
Researchers from Valencia (Spain), London (England) and Sul (Brazil) have performed research to develop adhesive materials that will prevent white stains from appearing on the teeth of people who use brackets.
Researchers at the University of Sheffield and Boston's Children Hospital, Harvard Medical School have created a robot that can be implanted into the body to aid the treatment of esophageal atresia, a rare birth defect that affects a baby's esophagus.
T cells play a key role in the body's immune response against pathogens. As a new class of therapeutic approaches, T cells are being harnessed to fight cancer, promising more precise, longer-lasting mitigation than traditional, chemical-based approaches.
Scientists at Université de Montréal have developed a unique technique to map, on a scale of milliseconds, the elasticity of the components inside a cell.
