Prof. Rudolf Jaenisch

Rudolf Jaenisch, M.D. Professor of Biology at MIT and Founding Member of the Whitehead Institute for Biomedical Research

Rudolf Jaenisch is a pioneering figure in the field of transgenic science, renowned for his groundbreaking work in genetic modification and epigenetic research. As a professor of biology at the Massachusetts Institute of Technology (MIT) and a founding member of the Whitehead Institute for Biomedical Research, Jaenisch has made numerous contributions to our understanding of cancer, neurological diseases, and the mechanisms of gene expression.

Jaenisch’s seminal work began in 1974, when he and his colleague Beatrice Mintz made a historic breakthrough by demonstrating that foreign DNA could be integrated into early mouse embryos. This achievement resulted in the creation of the first transgenic mammals—genetically modified mice—which became pivotal tools for studying the genetic basis of diseases such as cancer and neurological disorders.

Throughout his career, Jaenisch has focused on epigenetic regulation, which controls gene expression without altering the underlying DNA sequence. His work has been instrumental in the development of induced pluripotent stem (iPS) cells, which are capable of differentiating into any cell type. In 2007, his laboratory was one of the first to reprogram adult mouse cells into iPS cells, a discovery that has opened new avenues for regenerative medicine. His research has demonstrated the potential of iPS cells in treating diseases such as sickle cell anemia and Parkinson’s disease in animal models.

Beyond his research in stem cells and therapeutic cloning, Jaenisch has been a strong advocate for ethical practices in biotechnology. In 2001, he testified before the U.S. Congress against human reproductive cloning and has been a vocal supporter of advancing stem cell research using human cells for therapeutic purposes. His career has taken him from the University of Munich, where he received his doctorate in medicine, to leading research institutions like Princeton University and the Salk Institute, and ultimately to MIT in 1984.

Jaenisch’s contributions have been recognized by numerous prestigious awards, including the National Medal of Science (2010), the Wolf Prize in Medicine (2011), and the Benjamin Franklin Medal in Life Science (2013). He is also a member of the U.S. National Academy of Sciences and has served on several advisory boards in the field of genetics and stem cell research.

With a career spanning decades, Jaenisch continues to lead pioneering research that holds promise for the future of medical science, particularly in the areas of regenerative medicine and epigenetics.
