Special Considerations for Making Explants and Transplants with Xenopus tropicalis.
???displayArticle.abstract???
Although Xenopus laevis is an important model organism for embryological experimentation, the smaller, more genetically tractable, and faster developing Xenopus tropicalis provides advantages for using genetic approaches to understand developmental mechanisms. Explant cultures and transplants of X. tropicalis embryonic tissues present unique opportunities to examine embryonic tissue determination in a simplified setting. Here we demonstrate preparation of explants and transplants of preplacodal head ectoderm in order to illustrate these approaches; however, these methods apply broadly to tissues throughout the embryo. We focus on technical adjustments to accommodate the differences in size, tissue character, and rate of development between X. laevis and X. tropicalis With only modest modifications, X. tropicalis embryos are quite amenable to the same kinds of experimental manipulations as X. laevis.
