Regenerative powers in the animal kingdom explored in special issue of the Biological Bulletin
Date:8/18/2011

der the roles of stem cells and allorecognition in sea squirt regeneration. Nozomi Yoshinari and Atsushi Kawakami of Tokyo Institute of Technology review the process of fin regeneration in zebrafish and medeka and highlight the "compartments" or subpopulations of cells that are involved. MBL scientists Mark Messerli and David Graham review the roles of extracellular electrical fields (EFs) in controlling development, wound healing, and regeneration. Three of the issue's papers apply tools and insights from neuroscience to investigate neural regeneration in the snail (Ryota Matsuo and Esturo Ito of Tokushima Bunri University; M.J. Zoran of Texas A&M and colleagues; and in the sea squirt (H.N. Skld of University of Gothenburg and colleagues). Finally, the issue reprints a landmark article on the concept of polarity in regenerative processes by Thomas Hunt Morgan, an early leader in the field, which was first published in The Biological Bulletin in 1909.

In co-editing the issue, Smith and Olds write, "we were struck anew how many unanswered questions of basic science are central to regeneration," such as the "age-old question [of] whether, and to what degree, regenerative processes recapitulate the developmental program." But the field of regeneration today is "broad and vibrant," as this issue of The Biological Bulletin shows, with many efforts furnishing answers and clues.
