| We are interested in how embryonic pattern is generated. During
development, the egg which exhibits cylindrical symmetry must undergo
a number of symmetry breaking events in order to form the vertebrate
body plan and establish correct pattern along the body axes. We are
deeply interested in the gene regulatory networks that are necessary
to create critical signals in specific embryonic locations at
appropriate developmental stages. These signals must be carefully
orchestrated in order to generate forms that are essential to
function and the overall fitness of the organism.
Using the frog, Xenopus tropicalis, as an efficient vertebrate model
system, we are developing genetic tools to dissect these gene
regulatory networks. We are performing forward and reverse genetic
screens to identify mutants that affect early embryonic patterning.
In addition, we are developing new technologies to create F0
transgenic Xenopus embryos to rapidly and easily analyze cis-
regulatory elements that are essential to the formation of
regulatory genetic networks.
These studies are then complemented by mouse genetics to determine
conserved functions in mammals and better approximate human biology.
