In vitro models will minimize animal use in arthritis studies

22.10.2007
MU researchers have developed a model that mimics actual joints

It’s hard to think of scientists in laboratories working toward solutions for medical problems without mice or other laboratory animals, but animals’ roles in at least one major research laboratory may soon be minimal.

Researchers at the University of Missouri-Columbia's Comparative Orthopaedic Laboratory (COL) have developed an in vitro model using small sections of joint capsule and cartilage typically discarded that mimics arthritic joints. This "joint in a test tube" model can be used to investigate causes and mechanisms for the development and progression of arthritis and to screen new treatments such as pharmaceuticals. The MU research team which developed this model has shown that the results have valid and direct clinical implications for arthritis in dogs and humans.

Often, clinical research is limited by patient numbers, accessibility to appropriate samples and ethical considerations. Using in vitro models eliminates some of these barriers and allows researchers to better understand of the disease’s development, characteristics and responses to various injuries, treatments and loads. The in vitro model acts similar to an actual joint with the same histological, biochemical and molecular changes.

“These in vitro models will allow us to perform our research without using animals while still accurately mimicking situations in real life,” said James Cook, professor of veterinary medicine and surgery and the William C. Allen Endowed Scholar for Orthopaedic Research. “We can screen new drugs for arthritis in a more efficient and cost-effective way such that real progress is achieved more quickly.”

The in vitro models allow for all of the tissue in a normal joint to be "grown" together such that the different types of tissues can "communicate" as they do in the actual joint. COL researchers have shown that this system maintains the tissues' appearance, composition, and function so that they react to health and disease as they would in real life. The system then allows drugs, nutritional supplements and even exercise regimens to be tested on the in vitro model.

For example, scientists can determine the effects of pressure to the joints after running or walking using a bioreactor, a device which loads the tissues in the "test tube" environment. Using this new model, MU researchers will unlock clues, on a molecular level, as to why recovery is important in healthy athletes as well as people with arthritis.

“Using the joints in the test tubes will allow for greater flexibility when studying arthritis,” Cook said. “We can test literally hundreds of different loads on joints in a single day and show results in real time. It is strengthening our research as we are able to explain data on a molecular level and then translate it to what happens to people and pets that struggle with arthritis every day.

“These in vitro models also provide a much safer mechanism for investigating new drugs and therapies. If severe side effects occur, all we have do is assess what has happened to the tissues rather than trying to treat a laboratory animal or a patient with an adverse reaction.”

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
