In a study published in the journal Science, collaborators at NHGRI, the National University of Ireland, Galway, and the Whitney Laboratory for Marine Bioscience at the University of Florida, Augustine, reported that activation of the gene Tfap2 in adult stem cells in Hydractinia can turn those cells into germ cells in a cycle that can repeat endlessly.
