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.
The combination of a 2-Photon 3D-printer with an innovative hydrogel-based bioink allows the direct printing of 3D structures containing living cells at both the meso- and microscale.
A novel way to pinpoint and illuminate bone damage promises to make X-rays more efficient at diagnosing bone and other injuries, Flinders University researchers say.
A new automated process prints a peptide-based hydrogel scaffold containing uniformly distributed cells. The scaffolds hold their shapes well and successfully facilitate cell growth that lasts for weeks.
For sports fans, nothing beats seeing their favorite athletes compete at the top of their game. But a shoulder injury such as a badly torn rotator cuff threatens to pause or end the career of any athlete in sports ranging from football, basketball and baseball to golf and tennis.
A team from the Universitat Politècnica de València (UPV) and the CIBER Bioengineering, Biomaterials and Nanomedicine (CIBER-BBN) has designed and tested, at a preclinical level, a new biomaterial for the treatment and recovery of muscle injuries.
Age-related macular degeneration (AMD), which leads to a loss of central vision, is the most frequent cause of blindness in adults 50 years of age or older, affecting an estimated 196 million people worldwide. There is no cure, though treatment can slow the onset and preserve some vision.
Researchers at the University of Southampton have developed a new way of using nanomaterials to identify and enrich skeletal stem cells - a discovery which could eventually lead to new treatments for major bone fractures and the repair of lost or damaged bone.
The tooth fairy is a welcome guest for any child who has lost a tooth. Not only will the fairy leave a small gift under the pillow, but the child can be assured of a new tooth in a few months. The same cannot be said of adults who have lost their teeth.
Combining tissue engineering and regenerative medicine, scientists have fabricated a series of heart valve replacements with the ability to incorporate host cells, enabling them to regenerate and grow over time.
A groundbreaking new study led by University of Minnesota Twin Cities researchers from both the College of Science and Engineering and the Medical School shows for the first time that lab-created heart valves implanted in young lambs for a year were capable of growth within the recipient.
There is a great need to generate various types of cells for use in new therapies to replace tissues that are lost due to disease or injuries, or for studies outside the human body to improve our understanding of how organs and tissues function in health and disease.
The Wake Forest Institute for Regenerative Medicine is investigating how cats with chronic kidney disease could someday help inform treatment for humans.
It looks like science fiction: A machine dips into a shallow vat of translucent yellow goo and pulls out what becomes a life-sized hand.
According to the World Health Organization, one in six worldwide deaths have been attributed to cancer; however, these fatalities were not due to initial malignant tumors-;the deaths were caused by the spread of cancer cells to surrounding tissues and subsequent tumor growth.
Cardiovascular disease remains the number one cause of death globally. Unfortunately, the heart cannot regenerate new tissue, because the cardiomyocytes, or heart muscle cells, do not divide after birth.
Tissue engineering has long-depended on geometrically static scaffolds seeded with cells in the lab to create new tissues and even organs.
New hydrogel-based materials that can change shape in response to psychological stimuli, such as water, could be the next generation of materials used to bioengineer tissues and organs, according to a team of researchers at the University of Illinois Chicago.
By engineering common filter papers, similar to coffee filters, a team of NYU Abu Dhabi researchers have created high throughput arrays of miniaturized 3D tumor models to replicate key aspects of tumor physiology, which are absent in traditional drug testing platforms.
Muscle is the largest organ that accounts for 40% of body mass and plays an essential role in maintaining our lives.
Short Bowel Syndrome (SBS) is a medical disorder caused by a lack of a fully functional small intestine.
