Nanotechnology-enabled tissue engineering is receiving increasing attention. (nanowerk.com)
The ultimate goal of tissue engineering as a medical treatment concept is to replace or restore the anatomic structure and function of damaged, injured, or missing tissue. (nanowerk.com)
For bone tissue engineering, a special subset of osteoinductive, osteoconductive, integrative and mechanically compatible materials are required. (nanowerk.com)
Edwards, meanwhile, needed to understand how computer modeling worked and what was possible in the field of tissue engineering. (umich.edu)
The use of bone tissue engineering scaffold material, which can provide a microenvironment for bone regeneration, is an effective alternative strategy to support bone regeneration [ 6 ]. (biomedcentral.com)
Because this study aimed to develop a suitable tissue engineering scaffold from decellularized human foreskin tissue, the decellularization process needed to be optimized before we could even begin work with human tissue. (foregen.org)
In addition to my research initiatives, I have also been granted approximately 20 patents in the field of tissue engineering and have more than a dozen pending. (artbots.org)
Langer and Vacanti 19 defined tissue engineering as an interdisciplinary field that applies the principles of engineering and life sciences toward the development of biological substitutes that restore, maintain, or improve tissue function. (bvsalud.org)

The physical and chemical properties of the Cs/Gel/PHA scaffold with 0-10 wt% PBT were analyzed. (biomedcentral.com)
In addition to being one of the few sources of readily available and inexpensive human tissue, this young tissue has particular properties that give it an astoundingly high level of utility. (foregen.org)

In contrast to other materials that have previously been used to regenerate tissue, the risk of infection is intrinsically eliminated. (innovations-report.com)
Many biological tissue are hierarchical materials with structures spanning from meters down to atomic scales. (psi.ch)

If it works in pigs, the U-M researchers believe tissue-engineered flaps could revolutionize the field of facial reconstructive surgery. (umich.edu)

At the multi-cellular level, the goal is to program something to actuate muscle tissue rhythmically to sustain locomotion. (hackaday.com)

The device is anatomically shaped like a human meniscus and is intended, when sutured to the meniscus rim, to act as a tissue scaffold and fill the void left after meniscus loss. (genengnews.com)
Human babies, who can't yet produce heat by shivering, have greater stores of brown fat, so-called because it contains high levels of darker-hued mitochondria. (futurity.org)
It's scarce to see living humans or donated human tissues being used in the early stages of biomedical research. (foregen.org)
The animal tissue was submitted to the decellularization process, and we then analyzed the resulting matrices to determine what the optimal protocol for human prepuce tissue would likely be. (foregen.org)
