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.
Global nanotechnology company pSivida Limited has announced that it has signed an agreement with US based PureTech Development LLC to investigate and evaluate out-licensing opportunities for BioSilicon with an emphasis on tissue engineering, wound management and orthopedics.
Medical devices are traditionally thought of as fairly simple implants such as stents and hip replacements – pieces of plastic or metal that are placed in the body to handle a very specific function. But biomedical devices now on the drawing board are considerably more sophisticated and represent an unprecedented melding of man and machine.
Leaping tall buildings in a single bound may be out of the question, but the genetically engineered "supermice" in Ormond MacDougald's laboratory at the University of Michigan Medical School are definitely stronger than average.
Tissue engineers can choose from a wide range of living cells, biomaterials and proteins to repair a bone defect. But finding the optimum combination requires improved methods for tracking the healing process.
A University of Michigan research team has found that introducing a growth factor protein into a mouth wound using gene therapy helped generate bone around dental implants, according to a new paper in the February issue of the journal Molecular Therapy.
In a project that will likely be watched by football players, runners and other athletes, researchers at MIT and Harvard Medical School say they are developing an injectable gel that could speed repair of torn cartilage, a common sports injury, and may help injured athletes return to competition sooner.
Can a modern-day drug cure an age-old healing disorder that causes more harm than the actual injury?
Virginia Commonwealth University engineers and scientists have developed and patented a unique technique to grow three-dimensional tissues and organs in a mold made from material the human body naturally uses to repair wounds, potentially eliminating the chance for rejection.
The search for a stable, renewable source of blood vessels, especially for potential use in heart bypass surgery, has reached a milestone at the State University of New York at Buffalo.
University of Michigan researchers are testing a new procedure in which they can take a tiny piece of a person's mouth lining, grow it into a dollar-bill sized piece of tissue and graft that expanded piece into the donor's mouth to heal a wound.
While questions still remain about the nature and function of stem cells found in fat, a group of researchers and clinicians convened today in Pittsburgh at the Second Annual Meeting of the International Fat Applied Technology Society (IFATS) agreed that research should move forward with the ultimate goal of performing human clinical trials to test the cells' therapeutic potential for specific indications.
Researchers at the Technion-Israel Institute of Technology and Rambam Medical Center have demonstrated that heart cells grown from human embryonic stem cells can integrate into the host heart and help regulate its activity, becoming in effect a biological pacemaker.
A team of researchers at the Institute of Bioengineering and Nanotechnology (IBN) has moved one step closer to developing an ideal bone scaffold for reconstructive surgery.
Breast implants could one day be a thing of the past, as a new technology that allows patients to grow their own begins to take shape at the University of Melbourne.
Where other types of chips use electricity to stimulate nerves, this one instead tickles cells with minute amounts of chemicals. Because nerve cells normally communicate with each other by releasing chemicals known as neurotransmitters, the new device points to a more effective way of treating very delicate tissues, such as those in the eye and in the brain.
Tissue engineering - already used to build skin and bone - still holds enormous medical potential. The Commission plans to release a comprehensive package of EU rules to govern this promising field.
The proprietary material was originally developed by the Manchester based company to make artificial blood vessels, used to replace diseased arteries which can lead to heart attacks and strokes, and is capable of making significant improvements in surgery for vascular disease.
An MIT team has developed new technology that could jump-start scientists' ability to create specific cell types from human embryonic stem cells, a feat with implications for developing replacement organs and a variety of other tissue engineering applications.
For the first time, UCLA researchers have recreated the ability of mammalian cells to self-organize, forming evenly spaced patterns in a test tube. Published in the June 22, 2004 issue of the Proceedings of the National Academy of Sciences, the findings may help improve methods for regenerating tissue, controlling birth defects and developing new treatments for specific diseases.
A Massachusetts Institute of Technology team has developed new technology that could jump-start scientists' ability to create specific cell types from human embryonic stem cells, a feat with implications for developing replacement organs and a variety of other tissue engineering applications.
