The transplantation of cranial neural crest (CNC) expressing green fluorescent protein (GFP) in Xenopus laevis has allowed researchers not only to assess CNC migration in vivo but also to address many other experimental questions. Coupled with loss- or gain-of-function experiments, this technique can be used to characterize the function of specific genes during CNC migration and differentiation. Although targeted injection can also be used to assess gene function during CNC migration, CNC transplantation allows one to answer specific questions, such as whether a gene's function is tissue autonomous, cell autonomous, or exerted in the tissues surrounding the CNC. Here we describe a protocol for performing simple CNC grafts.
