Study TitleXenopus tropicalis regeneration timecourse
Study SummaryTo identify changes in metabolites that correlate with progression of tail regeneration, we collected a timecourse of tissues containing 250 um of tissue anterior to the wound site as well as all regenerating tissue at 0, 3, and 24 hours post amputation. We also collected the posterior 500 um of the developing tail to represent the metabolic profile of uninjured tissues. Tissues from 25 individuals were collected and frozen in more than 5-8 minutes per replicate before processing as in the methods. 104 metabolites were identified in these samples and relative peak intensities were compared to identify changes in abundance corresponding to regeneration. 42 differentially abundant metabolites were found using MetaboAnalyst, the majority of which were increased 24 hours post amputation. Further investigation of these 24 hours post amputation enriched metabolites revealed that these metabolites were largely associated with increased growth and nucleotide metabolism. This finding is in line with the growth of new tissue seen at this timepoint and also suggests that generation of nucleotides are a major factor in sustaining this growth.
