Research Activities
The focus of my laboratory is to
understand and manipulate the behavior of pluripotent and somatic stem
cells to understand mechanisms of human disease and develop novel
therapeutics. Our research utilizes systems biology to tease apart cell
behavior and pathophysiology. We often use pluripotent embryonic stem
cells (ESCs) as a model stem cell system because they are easier to grow
and manipulate in culture than somatic stem cells. In fact, pluripotent
stem cells have become the “new yeast”, enabling researchers to analyze
mammalian development at the transcriptome (mRNA & miRNA),
proteome, methylome, etc. systems level. Of course, yeast do not encode
miRNA so this is an critical difference supporting the use of human ESC
research. Importantly, we are now combining these systems approaches to
study human disease using induced pluripotent stem cells (iPSCs). We
believe such a systems genetics strategy will identify novel
therapeutic targets and therapeutics for many diseases including cancer.
This
work complements our previous endeavors which focused extensively on
using the mouse as a model for human disease and generated novel gene
trap vectors and a resource of more than 23,000 sequence annotated gene
trap mouse embryonic stem cell lines that represents mutations in more
than 4500 unique genes as well as numerous targeted clones as part of
the CMHD and NorCOMM resources (http://www.norcomm.org/index.htm). This resource is freely available to academic researchers as part of the international mouse knockout project.
