Theses and Dissertations
The exact mechanisms that regulate limb outgrowth the mouse embryo are unknown. Although there are several models, we favor a hypothesis where cells become polarized by signals secreted from the AER which orient their cell migration and/or divisions causing limb outgrowth. Clonal analysis has provided a mechanism to study cell behavior. We have generated a targeting construct containing the Fgf8 inhibitor, Sprouty2, in order to generate mutant clones for behavioral analyses in the limb. In order to more effectively study clonal behavior we report the modification of a novel clonal analysis approach, exo-utero surgery. We have modified, enhanced and proven …
