After infections or blood loss, the body must compensate for the loss of blood cells as quickly as possible. This has long been considered the task of the hematopoietic stem cells in the bone marrow. But scientists at the German Cancer Research Center (DKFZ) have now discovered in mice that a certain population of progenitor cells takes over this task: This accelerates the regeneration of the blood cells.

Acute Graft-versus-host disease (GvHD) is a life-threatening complication after leukemia treatment with allogeneic stem cell transplantation i.e. the transplantation of cells from another person. GvHD occurs when the transplanted immune cells are overly active and damage the receiving patient's healthy tissue. Researchers found that an endogenous molecule can mitigate this misdirected immune response.

Using animal-free methods to assess the hazard potential of chemicals to the nervous system of unborn children? An international research team including toxicologists from Konstanz and Düsseldorf has developed a testing battery based on human cells that has the potential to replace traditional methods for assessing developmental neurotoxicity.

During the growth and development of living organisms, different types of cells must come into contact with each other in order to form tissues and organs together. A small team working with Prof. Dr. Anne Classen of the Excellence Cluster CIBSS of the University of Freiburg has discovered that complex changes in form, or morphogenesis, during development are driven exclusively via the affinity of cells to each other.

Why do metastases often only appear after the original tumor has been surgically removed? Scientists from the German Cancer Research Center (Deutsches Krebsforschungszentrum, DKFZ) and the Mannheim Medical Faculty of Heidelberg University have now published an explanation for this phenomenon. They were able to identify a messenger substance of the cancer cells that locally promotes the growth of the primary tumor.

Laboratory studies of lung tissue usually require the removal of large amounts of human or animal tissue. Now scientists from the University of Freiburg’s Faculty of Medicine have succeeded in collaboration with American researchers in generating tiny quantities of lung tissue, so-called organoids, from just a few body cells in the lab.

Putting alternatives to animal testing into practice

Animal experiments are still central to biomedical research. However, it has become increasingly clear that not all of them are absolutely necessary. Alternative techniques exist. The new 3R-Netzwerk Baden-Württemberg is now seeking to promote these more vigorously - and improve animal welfare in cases where alternatives to animal testing are not available.

A new network has been set up in Baden-Württemberg aimed at reducing animal experiments as well as further improving animal welfare. It combines new approaches and measures at the state’s biomedical research locations, which are expected to limit stress in laboratory animals and steadily reduce the number of animals used in research in line with the 3R principles of Replacement, Reduction, and Refinement.

HepaRegeniX develops an active substance for liver regeneration

When the liver stops regenerating on its own, it might be possible in future for doctors to intervene with a chemical agent. Tübingen-based HepaRegeniX GmbH is developing a promising candidate with the aim of improving the treatment of both acute and chronic liver failure.

Miniature organs with great potential

Dr. Peter Loskill and his team at the Fraunhofer Institute in Stuttgart and the University Hospital of Tübingen are developing what is known as an "organ-on-a-chip" (OoC). An OoC is a microfluidic system that simulates small functional units of organ tissue. OoCs can be used in different ways: in basic and pharmaceutical research as well as in clinical research and application, where they might render many animal experiments…

Ludolph: diagnosing and treating neurodegenerative disorders

Ulm has long been a world leader in diagnosing and treating rare neurological disorders, notably amyotrophic lateral sclerosis (ALS), frontotemporal dementia (FTD) and Huntington's disease (HD). We spoke with Professor Albert C. Ludolph, spokesperson for the Ulm DZNE site, medical director of the Clinic for Neurology at the RKU (University and Rehabilitation Clinics of Ulm) and world-renowned ALS researcher.

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.

Cell marking opens up a window into the body

A new and particularly reliable method for marking cells can simplify research into diseases such as myocardial infarction, diabetes or Alzheimer's and reduce the use of test animals: Scientists from the University of Tübingen have developed a method by which they can target specific cell types in mice and monitor their behavior using positron emission tomography (PET). PET-based cell tracking allows scientists to observe complex life…

Transgenic mice in influenza research – risk assessment and vaccine development

A research team from Freiburg is developing a method for identifying human influenza viruses of animal origin. This could potentially improve measures taken to prevent imminent pandemics. The researchers are working with genetically modified mice. Transgenic mice also play a role in the development of a ’universal’ influenza vaccine.

Eric Gottwald: innovative 3D cell culture systems for pharmaceutical testing

Realistic alternatives to animal testing are more in demand than ever, especially in the drug development field. One possible solution is 3D cell cultures that possess the characteristics of the tissue from which they originate. Such systems were already developed at the Karlsruhe Institute of Technology (KIT) many years ago. Due to the huge demand for such systems, Prof. Dr. Eric Gottwald and two of his colleagues founded a company called…

A gene that regulates body heat and fat storage

Researchers from Heidelberg have shown that the organismal balance between heat production and energy storage is regulated by a gene called THADA. In animal experiments, knocking out the THADA gene leads to excessive food intake, obesity and sensitivity to cold. As humans spread throughout the world and settled in different climate zones, THADA was exposed to high selection pressure due to evolutionary adaptation. This explains why human…

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,…

Study shows correlation between intestinal gene activity and obesity

People with obesity suffer from more than just health problems related to their weight. They often feel socially stigmatised because their disease is often seen as a self-inflicted condition. A new study by the University of Hohenheim in cooperation with the eSwiss Medical and Surgical Center in St. Gallen now shows that severe obesity is closely associated with gene activity in the intestinal tissue. This activity is responsible for producing…

3D cell culture model for more efficient tumour research

The development of anti-cancer drugs is a lengthy process because results obtained in vitro in the laboratory often differ from what then occurs in a living organism. A group of researchers led by Prof. Dr. Margareta Müller at the Furtwangen University of Applied Sciences is therefore developing a new cell culture model that adjusts in vitro to real conditions.

Alcoholism: the molecular basis of addiction and deprivation

Scientists at the Central Institute of Mental Health in Mannheim use rats and mice to study the genetic basis and neurobiological mechanisms of alcohol addiction, the changes that occur during alcohol deprivation and the factors that favour a relapse. In translational research, the results from animal experiments are reviewed using alcohol-dependent patients in order to turn them quickly into preventive strategies and therapies.
