After amputation, the expression of desmin appears first in the distal end epidermis and the peritoneum 4 d PA. The expression in the peritoneum lasts to the 14 d PA when expression of desmin appears in the musculature, while that in the distal end epidermis only lasts to the 8 d PA when the connective tissue below begins to express desmin. Moreover, from the 4 d PA, musculature and epidermis of the tube foot begin to express desmin and the expressions last to the 20 d PA. From 8-14 d PA, musculature of the ambulacral plate expresses myogenin and the peritoneum also expresses myogenin from 14-20 d PA. All these results indicate that precursor cells for muscle regeneration in adult starfish A.rollestoni are mainly from the distal end epidermis and the parietal peritoneum.
