Abstract
The regenerative potential is expressed to a maximum extent in echinoderms and ascidians. They provide unique and valuable deuterostome models, closely related to vertebrates (man included), for an integrated approach exploring regeneration from tissue repair to asexual cloning. The comparison of results derived from different experimental models of echinoderms and ascidians and employing different approaches, in vivo and in vitro, provides an insight on specificity of regulatory mechanisms and processes governing large-scale pattern formation and information signalling storage between cells and tissues allowing a living system to reliably regenerate and maintain a complex morphology. Since in these animals, regenerative phenomena involve progenitor cells present in the circulating fluids or in the tissues, the crucial questions opened are those related to (1) stemness properties of responsible cells, in terms of origin and derivation (stem cells or dedifferentiated cells) and (2) activities (proliferation and/or migration), plasticity and differentiation potential (derived cellular phenotypes).Pubblicazioni consigliate
