Using embryonic stem cell biology to study the origins and progression of cancer
After receiving his DPhil from the University of Oxford, and periods as a postdoctoral scientist at the Institute Pasteur and Memorial Sloan Kettering Cancer Center, Peter Andrews joined the Wistar Institute in 1978. There he studied the biology of embryonal carcinoma (EC) cells, the stem cells of teratocarcinomas, a type of testicular cancer. EC cells not only provide a paradigm for the stem cell concept of cancer, but are also the malignant counterparts of embryonic stem (ES) cells, and their study has provided tools for the later study of human ES cell biology.
Peter Andrews moved to Sheffield to the Arthur Jackson Chair of Biomedical Science in 1992, and was the first scientist in the UK to work with human ES cells, following their derivation in 1998. A key discovery was that, on prolonged culture, human ES cells undergo non-random genetic changes that mirror changes also seen in EC cells from testicular cancer. While it is important to understand the causes and consequences of these changes for the use of human ES cells in regenerative medicine, they also provide a model for analyzing the progression of stem cell based cancers, a central current focus of the Andrews’ laboratory. Further work is focused on using induced pluripotent stem (iPS) cell techniques, a development of ES cell biology, to establish models to study pediatric cancers. This work is currently funded by the MRC and YCR; Peter Andrews also co-ordinates the International Stem Cell Initiative funded by the International Stem Cell Forum.
