Xenopus is a well proven model for a wide variety of developmental studies, including cell lineage. Cell lineage in Xenopus has largely been addressed by injection of tracer molecules or by micro-dissection elimination of blastomeres. Here we describe a genetic method for cell ablation based on the use of tBid, a direct activator of the mitochondrial apoptotic pathway. In mammalian cells, cross-talk between the main apoptotic pathways (the mitochondrial and the death domain protein pathways) involve the pro-death protein BID, the active form of which, tBID, results from protease truncation and translocation to mitochondria. In transgenic Xenopus, restricting tBID expression to the lens-forming cells enables the specific ablation of the lens without affecting the development of other eye structures. Thus, overexpression of tBid can be used in vivo as a tool to eliminate a defined cell population by apoptosis in a developing organism and to evaluate the degree of autonomy or the inductive effects of a specific tissue during embryonic development.
