Wound care: new nanoscale bioabsorbable dressing

06.06.2019

Scientists at Texas A&M University are harnessing the combined power of organic nanomaterials-based chemistry and a natural product found in crustacean exoskeletons to help bring emergency medicine one step closer to a viable solution for mitigating blood loss, from the hospital to the battlefield.

Tissue Engineering: producing tissue and organs through lithography

28.05.2019

The production of artificial organs is a hot research topic. In the near future, artificial organs will compensate for the lack of organ donations and replace animal experiments. Although there are already promising experiments with 3D printers that use a "bio-ink" containing living cells, a functional organ has never been created in this way.

Multi-organ chips: Drug research without animal testing at vasQlab

15.05.2019

New active substances that are suitable for drugs are initially tested in animal experiments. However, the results cannot always be transferred to the human organism. At the Karlsruhe Institute of Technology, Prof. Ute Schepers from vasQlab explains how active substances can be tested in human tissue without endangering human health.

Organ bioprinting gets a breath of fresh air

15.05.2019

Bioengineers have cleared a major hurdle on the path to 3D printing replacement organs with a breakthrough technique for bioprinting tissues. The innovation allows scientists to create exquisitely entangled vascular networks that mimic the body's natural passageways for blood, air, lymph and other vital fluids.

Implanted heart patch could limit muscle damage after heart attack

25.04.2019

Researchers have designed a new type of adhesive patch that can be placed directly on the heart and may one day help to reduce the stretching of heart muscle that often occurs after a heart attack.

Regenerative heart valves: from simulation to replacement

23.07.2018

Every year, more than 250,000 patients worldwide receive heart valve implants. Children require repeated replacement surgery because their bodies are still growing, the prosthetic heart valves are not. Regenerative heart valves solve this problem. Until now, we have only been able to monitor how these living implants develop in the body after the fact. Computer models now make this predictable.

Tissue engineering: how to grow a bypass

23.04.2018

A bypass is a complicated structure. It is either made of synthetic materials that can cause blood clots and infections or created by using the patient’s veins. However, the latter often does not yield adequate material. A newly developed bioreactor could solve this problem in the future. It is designed to tissue engineer vascular grafts by using the body’s own material.
