The behaviour of the outer epithelial cells of a mantle allograft implanted into the mantle connective tissue of the mussel Hyriopsis schlegeli was examined using light and transmission electron microscope. Ultrastructural observations revealed that the outer epithelial cells of an implanted allograft separated from their original basement membrane, emerged from the periphery of graft, very soon flattened and emigrated crawling in contact with the plasma membrane of agranular hemocytes in the recipient hemocyte capsule surrounding the graft. In this behaviour the emigrating outer epithelial cells spread out as a monolayer of continuous cell sheet of flattened cells which connected each other by desmosome. It seems that the marginal cells situated in the growth front of the continuous epithelial cell sheet stretch some filopodia from their leading edge, emigrate recognizing the plasma membrane of recipient agranular hemocytes by contact and regenerate into a monolayer of pearl-sac epithelium which aligns on the inside of hemocyte capsule.
