13/05/2022Your immune system’s ability to combat COVID-19, like any infection, largely depends on its ability to replicate the immune cells effective at destroying the SARS-CoV-2 virus that causes the disease. These cloned immune cells cannot be infinitely created, and a key hypothesis of a new study is that the body’s ability to create these cloned cells falls off significantly in old age.

13/04/2022One cutting-edge cancer treatment exciting researchers today involves collecting and reprogramming a patient’s T cells – a special set of immune cells – then putting them back into the body ready to detect and destroy cancerous cells. Although effective for widespread blood cancers like leukemia, this method rarely succeeds at treating solid tumors.

15/03/2022Radiation therapy is one of the cornerstones of cancer therapy. However, some types of tumor respond little or hardly at all to radiation. If it were possible to make tumor cells more sensitive, treatment would be more effective and gentler. Empa and ETH Zurich researchers have now succeeded in using metal oxide nanoparticles as "radiosensitizers" – and in producing them on an industrial scale.
14/03/2022In large bacterial populations, mutants that evolve relatively late resist antibiotic treatment more effectively, while smaller populations rely on less effective mutations that appear at an earlier point in time.

01/12/2020How do cells react to certain drugs? And how exactly is new tissue created? This can be analyzed by using bioprinting to embed cells in fine frameworks. However, current methods are often imprecise or too slow to process cells before they are damaged. At the TU Vienna, a high-resolution bioprinting process has now been developed using a new bio-ink.
01/12/2020Implants, prostheses and various other components made of plastic, metal or ceramics are already being produced by additive manufacturing. But skin, blood vessels or entire organs from the printer – is that possible? For years now, intensive research has been underway into the production of biologically functional tissue using printing processes. Some things are already possible with bioprinting.
01/12/2020It aims at the production of test systems for drug research and gives patients on the waiting lists for donor organs hope: bioprinting. Thereby biologically functional tissues are printed. But how does that actually work? What are the different bioprinting methods? And can entire organs be printed with it? These and other questions are examined in our Topic of the Month.
01/12/2020The big hope of bioprinting is to someday be able to print whole human organs. So far, the process has been limited to testing platforms such as organs-on-a-chip. That's because the actual printing process already poses challenges. Scientists need suitable printing materials that ensure the cell's survival as it undergoes the procedure. The Fraunhofer IGB is researching and analyzing this aspect.
03/02/2020Regenerative medicine aims to replace damage in the body with functional tissue and restore normal function. The first defense for large defects are implants made of hydrogels, designed to promote cell growth. They need their own blood supply, which is a problem when it comes to larger implants because you cannot regulate where and how the blood vessels grow - until now.
03/02/2020Severe wounds heal slowly and leave scars. This is why we have been using regenerative therapies for some time now to accelerate and improve healing. They also help to avoid permanent damage. Still, complex applications like replacing organs or limbs will rather remain vision than become reality for a long time.
08/10/2019The healthcare market offers a multitude of microscopes that make cells visible to the human eye. The same applies to AI-based software for image analysis. After taking the microscopic images, scientist are faced with large volumes of scans with usually low resolution. Yet when all aspects merge together, they open up a the world of digital pathology.
01/02/2019The liver, nervous tissue or the intestines: all are important human organs that have in the past been tested for their function and compatibility using animal or in vitro test methods. In recent years, TissUse GmbH, a spin-off of the Technical University of Berlin (TU Berlin), has launched multi-organ chip platforms. But that’s not all.
01/02/2019In vitro processes and animal tests are used to develop new medications and novel therapeutic approaches. However, animal testing raises important ethical concerns. Organ-on-a-chip models promise to be a feasible alternative. In a system the size of a smartphone, organs are connected using artificial circulation.
01/02/2019Organ-on-a-chip systems are technically a great enhancement of medical research because they facilitate testing of active ingredients on cell cultures in the chambers of a plastic chip. This replaces animal testing and improves patient safety. That being said, they are not a true-to-life replication of the human body and can only simulate a few functions and activities.
09/07/2018People who are not ill and do not show any symptoms typically do not visit the doctor. And while most people know that preventive medical checkups for cancer, for example, are important, they still avoid them. They tend to be very hesitant because the doctor might detect a serious illness. In the future, a new type of implant could make it easier to go to a screening test.
22/06/2018A drop of blood provides a lot of valuable information. However, it takes several hours to analyze the blood of a patient and make a diagnosis. This takes away a lot of time that's crucial for treatment. A new method intends to considerably speed up this process by testing the cells in the blood in terms of their deformability and immune response.
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.
22/02/2018Here on Earth, all experiments are bound by gravitation. Yet, freed from gravity's grip, tumor cells, for example, behave in an entirely different way. As part of the "Thyroid Cancer Cells in Space" project by the University of Magdeburg, smartphone-sized containers carrying poorly differentiated thyroid cancer cells are sent into space.
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.
