The Use of Small Molecules to Dissect Developmental and Regenerative Processes in Axolotls.

The axolotl provides an interesting model organism to study different biological processes that are of interest to basic biological sciences and biomedical research. Although axolotls have been in labs for close to 160 years, genetic manipulations still represent a major challenge for most labs. The use of small molecules to target specific signaling pathways allows studies to proceed in animals that are difficult to manipulate genetically. This chapter provides a description of how we administer these chemicals to axolotls.
