Present knowledge on what processes are necessary for organ regeneration is highly limited. This project uses an animal with striking regenerative capacities, the sea cucumber, to probe at the genes and signal pathways that are associated with regeneration processes. The working hypothesis is that some of the identified genes (and their associated signal pathways) are important players in the regeneration of the intestine and that by studying them the mechanisms involved in the control of regenerative processes will be discovered. The project focuses on genes that are known to be involved in embryonic development and cell death in order to define their role during regeneration of the intestine. The results will advance our understanding of organ regeneration and in particular on the limits that might be encountered in humans and higher vertebrates. The work will take place at the University of Puerto Rico, a Hispanic serving institution. Most of the participating students are underrepresented minorities and women. Thus, the project will impact the training and professional development of underrepresent groups in science.
