26.11.2019Around 60 international experts met on November 7 at the Fraunhofer Institute for Silicate Research ISC in Wuerzburg to report on the state of the art in the field of 3D tissue models and prevention of animal experiments in the development of pharmaceuticals and medical devices.
04.11.2019Scientists of Tomsk Polytechnic University jointly with the University of Montana (USA) proposed a new promising material for regenerative medicine for recovery of damaged tissues and blood vessels.
22.10.2019Tissue growth and the behavior of cells can be controlled and investigated particularly well by embedding the cells in a delicate 3D framework. This is achieved using additive 3D printing methods - so called "bioprinting" techniques. However, some methods are very imprecise or only allow a very short time window in which the cells can be processed without being damaged.
09.10.2019Physiological parameters in our blood can be determined without painful punctures. Empa researchers are currently working with a Canadian team to develop flexible, biocompatible nanocellulose sensors that can be attached to the skin. The 3D-printed analytic chips made of renewable raw materials will even be biodegradable in future.
01.10.2019Organs, muscles and bones are composed of multiple types of cells and tissues that are carefully organized to carry out a specific function. For example, kidneys are able to filter waste from the blood because of how their specialized cells and tissues are arranged. Disrupting this organization dramatically affects how cells and tissues do their job effectively.
25.09.2019The Fraunhofer FEP has developed a process, called SULEEI, which makes it possible to sterilize and preserve decellularized pericardial tissue by means of photo-initiated ultraviolet crosslinking with low-energy electron irradiation.
24.09.2019Researchers from Uppsala University have revealed for the first time a mechanism for how new blood vessels are formed and have shown the importance of this mechanism for embryo survival and organ function. The results could be developed to control the formation of new blood vessels in different diseases. The new study is published in the journal EMBO Reports.
23.09.2019For patients waiting for donor organs, every day can mean the difference between life and death. Making things even more complicated is the fact that not every organ is a compatible match with the patient. It would mean enormous progress if we could grow organs from the patient's own cells in the lab. That's why patients with heart disease place big hope in tissue engineering.
23.07.2018Every 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.
23.04.2018A 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.
08.01.2018Few patients with heart failure are fortunate enough to receive a donor's heart. Ventricular assist devices (or heart pumps) have been around for several years and are designed to buy time as patients wait for a transplant. Unfortunately, the body doesn't always tolerate these devices.
