Explore the fascinating regenerative capabilities of Hydra through this 30-minute lecture that examines the cellular and molecular mechanisms underlying this organism's remarkable ability to regrow lost body parts. Discover the different cell types involved in Hydra regeneration and learn how gene expression patterns change during the regenerative process. Investigate the complex signal transduction pathways that coordinate cellular responses and tissue reformation. Compare and contrast two fundamental regenerative strategies - morphallaxis, where existing tissues reorganize and repattern to restore missing structures, and epimorphosis, which involves the growth of new tissue to replace lost parts. Gain insights into how Hydra serves as a model organism for understanding regenerative biology and the potential applications of this knowledge to broader biological and medical contexts.
