Tissue Engineering News and Research

RSS

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.

Griffith researchers pioneer use of 3D bioprinting to replace missing teeth, bone

The discomfort and stigma of loose or missing teeth could be a thing of the past as Griffith University researchers pioneer the use of 3D bioprinting to replace missing teeth and bone.

New 3D micro-scaffold technology promotes reprogramming of stem cells into neurons

National Institutes of Health-funded scientists have developed a 3D micro-scaffold technology that promotes reprogramming of stem cells into neurons, and supports growth of neuronal connections capable of transmitting electrical signals.

Newly developed biodegradable polymer grafts can help repair the spine

Remember those colorful "grow capsules" that blossom into animal-shaped sponges in water? Using a similar idea, scientists have developed biodegradable polymer grafts that, when surgically placed in damaged vertebrae, should grow to be just the right size and shape to fix the spinal column.

New research reveals underlying biomechanics involved in meniscus fibrocartilage function

Knee injuries are among the top five reasons people visit an orthopedic surgeon for treatments, which include 719,000 total knee replacements performed annually in the United States. Now, new research reveals underlying biomechanics that may be involved in meniscus fibrocartilage function as well as dysfunction and could guide novel treatments for some of the most debilitating and costly orthopedic problems in the U.S., including meniscus tears and age-related joint degeneration.

Scientists find that lifespan of supportive cells in tumor may control cancer metastasis

Researchers have discovered that eliminating cells thought to aid tumor growth did not slow or halt the growth of cancer tumors. In fact, when the cancer-associated fibroblasts (CAFs), were eliminated after 10 days, the risk of metastasis of the primary tumor to the lungs and bones of mice increased dramatically.

NJIT students building low-cost water filter for people suffering from kidney disease in rural Sri Lanka

Backed by a grant from the U.S. Environmental Protection Agency, an interdisciplinary, student-led team from New Jersey Institute of Technology is building a low-cost water filter for villagers in the north central farming region of Sri Lanka who are suffering from high rates of chronic kidney disease.

Duke engineers develop technique to make artificial arteries that produce biochemical signals

Duke engineers have developed a technique to make artificial arteries that naturally produce biochemical signals vital to their functions. The technique is also ten times faster than current methods for tissue engineering of blood vessels.

Wake Forest Baptist scientists prove feasibility of printing living tissue structures for surgical implantation

Using a sophisticated, custom-designed 3D printer, regenerative medicine scientists at Wake Forest Baptist Medical Center have proved that it is feasible to print living tissue structures to replace injured or diseased tissue in patients.

Vanderbilt researchers use cotton candy machines to produce artificial capillary system

For several years, Leon Bellan, assistant professor of mechanical engineering at Vanderbilt University, has been tinkering with cotton candy machines, getting them to spin out networks of tiny threads comparable in size, density and complexity to the patterns formed by capillaries - the tiny, thin-walled vessels that deliver oxygen and nutrients to cells and carry away waste.
