Mammalian Development, Human Pathology from Cancer to Neuropschiatric Disorders


Our research efforts are directed towards the analysis of the developmental programs mediating pattern formation, organogenesis and neurogenesis in the mouse. Towards achieving these goals, we have pioneered the technology required for generating mutations in any gene in the mouse. This technology employs the exchange of DNA sequences, by homologous recombination, between exogenous, newly added DNA sequences and the cognate chromosomal DNA sequences in embryo-derived mouse stem (ES) cells. This process is referred to as "gene-targeting." The ES cells containing the desired targeting event are then used to generate mouse germ line chimeras, capable of transmitting the mutation to their progeny.

We are using this technology to determine the function of genes believed to mediate important developmental decisions in the mouse embryo. This technology is also being used to generate mouse models for human genetic diseases from cancer to neuropsychiatric disorders . Such animals allow a deeper analysis of the pathogenesis of the human disease, as well as provide appropriate subjects for testing new therapeutic protocols including somatic gene therapy. Eventually, this technology should also provide an avenue for directly correcting genetic defects in humans via somatic gene therapy.
