Premetamorphic Xenopus laevis tadpoles limb bud cells respond to thyroid hormone by proliferation and subsequent differentiation. The goal of this experiment is to identify the genes involved in the TH-induced proliferation pathway in developing tadpole limb bud and compare it to TH-induced proliferation and differentiation program in tadpole brain. Xenopus tadpoles (NF54) were treated with 1 mM methimazole in 0.1 X MMR solution for 1 week to block the endogenous TH production and reduce the TH present in the system of the tadpole. They were then treated with 100 nM T3 in 1 mM methimazole and 0.1 x MMR for another 24h and 48h or without T3 for 48h (control group). Limb buds were dissected at the end of the experiment.
