They have already demonstrated applications in chicken... view more Credit: A. Heddergott / TUM Researchers at the TUM have demonstrated a way to efficiently study molecular mechanisms of disease resistance or biomedical issues in farm animals. Researchers are now able to introduce specific gene mutations into a desired organ or even correct existing genes without creating new animal models for each target gene. This reduces the number of animals required for research.. CRISPR/Cas9 enables desired gene manipulations
