Scientists initiate first ethical guidelines for organs cultivated in vitro
Organ models, which are cultivated in the laboratory from human stem cells and grow into living tissue, are one of the most important scientific breakthroughs of recent years. Scientists, patients and the wider public have high hopes for this emerging field of research, as so-called "organoids" have a huge potential in terms of research and modern medicine . In-vitro organ models allow complex organ development studies and pathogenetic analyses to be carried out directly in human tissue. New substances and therapies can be tested on human material much more quickly using this technology. Regenerative medical practice could conceivably cultivate the required tissue in the laboratory from the cells of a patient and, lessen dependency on organ donations. The use of organoids could also significantly reduce the need for animal experiments, although biologists believe these cannot be completely eliminated in the foreseeable future. Organoids -- high hopes an d bioethical dilem...
