In recent years, many efforts have been made by scientists and biomedical engineers to develop ex-vivo models of human tissues and organs using 3D printing techniques (see our report HERE) for various purposes. In particular, the potential organoids using 3D techniques can be used to assess the functions of different human organs, deepen our understanding of various diseases, and also serve as a substrate for experimentation with new drugs. Now, a webinar in Nature ( webcasts) has evaluated the possibility of detecting specific drugs for the treatment of malignant tumors, especially colorectal tumors. Using this technique, they evaluated more than 3000 molecular compounds that have been identified and validated to prevent the recurrence of colorectal cancer, which, from a medical and bioethical point of view, is very positive.
