Advances in Decoding Axolotl Limb Regeneration

The salamander experimental toolset has now largely caught up with the interest in understanding limb regeneration, finally allowing precise experimentation at a cellular and molecular level. A huge amount of transcript data has emerged from which to gather clues about how limb regeneration occurs. Differential gene expression analysis has enabled the identification of transcripts that are highly enriched, as well as highly repressed, in key...
