Microrobots have the potential to revolutionize medicine. Researchers at the Max Planck ETH Centre for Learning Systems have now developed an imaging technique that for the first time recognises cell-sized microrobots individually and at high resolution in a living organism. This is an important step towards precise control of the robots and their clinical translation.

Metastatic breast cancer cells abuse macrophages, a type of immune cell, to promote the settlement of cancer metastases in the lungs. The reprogrammed macrophages stimulate blood vessel cells to secrete a cocktail of metastasis-promoting proteins that are part of the so-called metastatic niche.

Elastin as artificial muscle material - 02/03/2022

Artificial muscle from proteins for diverse future applications

As far as diversity and complexity are concerned, proteins are nature's smallest marvels. Biotechnologists have already used natural proteins as a basis for the development, bespoke design and production of artificial systems. This is what the livMatS cluster of excellence at the University of Freiburg has been doing. Researchers in the cluster have successfully produced an artificial muscle from elastin that functions autonomously.

Dr. Stefan Schiller and Dr. Matthias Huber from the University of Freiburg’s livMatS Cluster of Excellence have succeeded in developing a muscle solely on the basis of natural proteins. The autonomous contractions of the material, which the researchers presented in the journal Advanced Intelligent Systems, can be controlled with the help of pH and temperature changes.

The mechanisms by which the body measures temperature and regulates its own body heat are vital, but still poorly understood. The discovery of the first heat sensor on nerve cells in the skin, for which the U.S. molecular biologist David Julius received this year's Nobel Prize for Medicine, was therefore pioneering.

Cyber Valley researchers have created medical educational tools that could potentially train the surgeons of the future, much like flight simulators train pilots. The team developed a range of artificial organ phantoms to serve as training platforms for surgeons. Thanks to the structured data of experienced medical professionals, a quantitative and objective assessment of a trainee’s skills can be assessed in real time.

On the one hand, blood vessels supply tumors with nutrients and, on the other, enable cancer cells to spread throughout the body. The settlement of circulating tumor cells in a distant organ is promoted by factors whose production is induced by the primary tumor itself. Scientists have now identified a new growth factor produced by blood vessels that enables tumor cells to metastatically colonize organs.

The bacterium Staphylococcus epidermidisis primarily a harmless microbe found on the skin and in the noses of humans. Yet some strains of this species can cause infections – in catheters, artificial joints, heart valves, and in the bloodstream – which are difficult to treat. These bacteria are often resistant to a particularly effective antibiotic, methicillin, and are among the most feared germs in hospitals.

Brain tumor cells with a certain common mutation reprogram invading immune cells. This leads to the paralysis of the body's immune defense against the tumor in the brain. Researchers from Heidelberg, Mannheim, and Freiburg discovered this mechanism and at the same time identified a way of reactivating the paralyzed immune system to fight the tumor.

What role do the lymphatic vessels play in the metastasis of cancer cells? Scientists from the German Cancer Research Center and the Mannheim Medical Faculty of the University of Heidelberg developed a method to investigate this question in mice. The aim of the work was to identify new ways to block the dangerous colonization and spread of tumor cells.

Tumour metastasis

Cancer is usually not curable when metastases have formed in the body. Metastases are often resistant to drugs that have successfully eliminated the primary tumour. The basic features of the complex process of metastasis are now known, but many details still remain elusive. Intensive research activities are focusing on new therapeutic concepts aimed at developing effective anti-metastatic therapies.

Alternative to animal experiments - 21/03/2018

Drug tests using miniature organs

At present, potential new drugs have to be tested on animals before they can be used on humans. However, results obtained from animals are not always transferrable to the situation in humans, which is why researchers around the world have long been seeking alternatives. Miniature human organs that can be used to test the efficacy of potential human drugs might provide a solution.

An artificial heart valve with the potential to grow

About 30,000 artificial heart valves are implanted in Germany every year. The durability of these heart valves presents a major challenge, requiring them to be exchanged time and again, especially in young patients. Researchers from the Stuttgart Fraunhofer Institute for Interfacial Engineering and Biotechnology IGB have developed a new artificial heart valve material on which cells that are naturally present in a patient’s blood can form new…

New research consortium to develop new liver cancer treatments

The causes, signs and symptoms of liver cancer are extremely complex. Investigating them requires the collaboration of many experts across university and regional boundaries. A new transregional research group is now studying the complex overall mechanisms at the cellular, genetic and molecular level in order to develop new concepts and drugs for treating liver and bile duct cancers.

On 24 April 2017 is "World Day for Laboratory Animals" – the BIOPRO provides information about this topic. In Baden-Württemberg alone, up to 600,000 animals are used for scientific purposes every year. In order to reduce their pain and suffering as much as possible, researchers all over the world are working on the development of innovative methods to replace animal experiments, including cell culture methods for drug analysis,…

FlexiTel – microsensors for tissue monitoring

When soft tissue is transplanted, for example in a patient undergoing tumour surgery, care must be taken to ensure that the new tissue is connected to the blood system in the area where the tumour has been removed. How well this works is difficult to find out, especially in the case of deep-seated defects. Partially implantable microsensor probes called FlexiTel have the potential to improve this situation by monitoring success during the first…

DNA capture molecules wanted for cells

Artificial blood vessels made of special polymers are no longer a pipedream. However, one problem that needs to be solved is that the artificial vessels have to be compatible with tissue. One solution could be to dupe the body into thinking that the artificial vessels are real by coating their inside walls with the patient’s own cells. Researchers from Reutlingen have developed a microfluidic chip that identifies molecules that can capture the…
