Abstract: | The Wnt5 protein localization in holothurian Eupentacta fraudatrix tissues was examined in the norm and during regeneration. In healthy E. fraudatrix, Wnt5 was found in solitary cells of the hypodermis and in the radial nerve cords. During regeneration, the number of Wnt5 positive cells increased. They were observed in the connective tissue of the body wall and the pharyngeal bulb, in nervous system tissues, the coelomic epithelium, and amoebocytes. The Wnt5 protein may participate in regulating the regeneration in the holothurian E. fraudatrix; it probably modulates cell migration, extracellular matrix reorganization, and neurogenesis. |
