Wednesday, 09 March 2011 16:25

A team of doctors from Mexico and the United States has been successful in engineering artificial urethras using the body´s own cells. The urethras are fully functional six years after transplant. The structure and function  are nearly the same as naturally grown tissue.

Scientists from the RWTH Aachen in cooperation with the Christian Albrecht University of Kiel (CAU) and the Scripps Research Institute (San Diego, USA) published a new stem cell research method without animal use in the magazine Nature Methods (6.3.11).

A more and more common method will help scientists to identify 13 risk genes, whereupon the influence of genes which cause a coronary heart disease could be greater than expected by now.

The workshop intends philosophical and historical discussion about the relation between computer simulations and experimentation.

To ensure that the best use has been made of existing information, particularly information on existing vertebrate tests, the European Chemicals Agency’s (ECHA) publishes all test proposals involving vertebrate animals, for endpoints specified in Annexes IX and X under REACH, on this webpage before the testing is carried out.

From the end of March on human skin modells shall literally be produced on a conveyor belt by IGB in Stuttgart. At first, the scientists of the Fraunhofer Institute for Interfacial Engineering and Biotechnology (IGB) want to produce 5.000 thumbnail seized skin models per month, fully automated and ready for dispatch.

The Rhineland-Palatinate's Ministry of the Environment is funding a two-year cooperation project between the Institute of Human Genetics at the Heidelberg University Hospital and the Institute for Biological interfaces at the Karlsruhe Institute of Technology (KIT), the objective of which is to develop alternatve methods to animal experiments.

January of this year saw the launch of the research project DETECTIVE, funded with more than eight millinon euros and led by Professor Dr. Jürgen Hescheler of the University of Cologne. DETECTIVE is a project of the 6th EU Research Framework Programme in collaboration  with the COLIPA (European Cosmetic Association). The project's oblective is to help ascertain endpoints (study objectives) and bio-markers for the long-term toxicity examinations with the assistance in vitro systems.

The world largest producer of tea, e.g. Lipton tea, Unilever, has announced that it has stopped all animal experiments for tea or tea ingredients, effective immediately, unless required by law.

A new EU regulation puts an end to the so-called mouse bio-assay which has used for testing toxin contamination in shellfish, instead requiring an animal-free chemical testing procedure.
