Summary of scientific research
Beatrice Mintz discovered the underlying relationship between development and cancer. She first showed that development is based on an orderly hierarchical succession of increasingly specialized small groups of precursor or "stem" cells, expanding clonally. She proposed that cancer involves a regulatory aberration in this process, especially in the balance between proliferation and differentiation. These views were based on a series of methods of her own design, for construction and analysis of chimeric and transgenic mouse models. The models enabled the experimental study of development and of cancer within the framework of the whole organism throughout life. She produced chimeric mice (which she at first termed "allophenic") by inclusion of two genetically different cells in the early mouse embryo, thereby revealing the clonal organization. Mintz then devised modifications of chimerism to examine the roles of stem cells in cancer. Her lab. found that mouse teratocarcinoma stem cells developed normally in a normal embryo environment. This led to many new kinds of experiments in many laboratories, aimed at defining the role of a normal microenvironment on cancer cells. Her new experiments also showed that stem-like cancer cells could be grown in culture and used as "messengers" to convey specific-DNA into the organism. Later, the DNA was injected directly into the fertilized egg. Her lab. used that method to produce a mouse model of malignant melanoma resembling the human disease, so as to explore possible treatments.
