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.
A breakthrough in polymer development means that soon there may be a radical new treatment for people with broken bones - a special kind of material that can 'glue' the bone back together and support it while it heals. The polmer material is designed to break down as the bone regrows leaving only natural tissue.
Embryonic stem cells may hold the key to regenerating damaged heart muscle, when transplanted within a 3-dimensional scaffold into the infracted heart, according to a new study coming out in June in the Journal of Heart and Lung Transplantation.
Cells derived from the inside of a tooth might someday prove an effective way to treat the brains of people suffering from Parkinson's disease.
Orthonics, Inc., an Atlanta start-up company developing new biomaterials for spinal disc repair and regeneration, has received initial funding from Viscogliosi Brothers, LLC, a New York-based closely held venture capital/private equity and merchant banking firm focused on the musculoskeletal/orthopedics industry. Terms of the funding were not disclosed.
Using technology borrowed from the National Aeronautics and Space Administration (NASA), scientists at the University of Pittsburgh's McGowan Institute for Regenerative Medicine have taken the first steps toward successfully preserving ovarian tissue from rats and mice in culture, including immature egg follicles, according to a study in the current issue of the journal Tissue Engineering.
More than 10 million Americans undergo surgical tooth extractions every year, and the procedure invariably involves some loss of bone from the tooth socket. This bone loss is problematic for dentists because it can compromise both the functional and esthetic outcomes of treatment involving dentures and bridges. Significant losses of bone also make it difficult for surgeons to properly fit dental implants to the ridge of the jawbone without requiring additional surgical procedures.
New treatments for breast cancer, skin and wound healing and obesity will be revealed at an international conference in Cairns, Australia next week.
Eight out of every 1000 children are born with a heart problem. Out of these, every fifth child needs a heart valve. While today’s mechanical or biological heart valves allow children to continue their lives, a research team at RWTH is developing a significantly more compatible heart valve that grows along with the body’s growth.
The University of Missouri Friday announced the discovery of a process to minimize the side effect of painful arthritis that develop after knee surgeries. The procedure will be tested in human clinical trials this summer if the process is approved by the Food and Drug Administration, the Columbia, Mo-based school said.
When biologist Barbara Boyan discovered science’s first proof of biochemical differences between male and female cartilage cells, she began to question the approaches she and other researchers were taking to study cells. Was their thinking biologically relevant?
Pathbreaking developments in tissue engineering and regenerative therapies are facilitating the design and growth of new organs in labs using biopolymer scaffolds and matrices. Analysis of potential markets for tissue engineering reveals that basic problems such as vascularity must be solved before such implants can gain acceptance as standard treatment methods.
Johns Hopkins University researchers have created a new class of artificial proteins that can assemble themselves into a gel and encourage the growth of selected cell types. This biomaterial, which can be tailored to send different biological signals to cells, is expected to help scientists who are developing new ways to repair injured or diseased body parts.
Scientists at the University of Toronto are taking regenerative medicine to a new dimension with a process for guiding nerve cells that could someday help reconnect severed nerve endings.
