Neurulation is an important stage in the embryo development of vertebrate, during which the ectoderm thickens into epidermal neural plate and then forms neural folds and neural tube.

脊椎动物胚胎发育过程中，神经胚期是一个重要的发育时期。这个阶段胚胎外胚层增厚形成上皮型神经板，神经板两侧隆起形成神经褶，随后神经褶两侧向背中线合拢并愈合成神经管。

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.

创伤后第4 d，顶端表皮层及体腔上皮中首先出现了desmin表达，体腔上皮中desmin的表达一直持续到第14 d，此时其上方的肌肉组织中也出现了desmin表达；而顶端表皮层中desmin的表达仅持续到第8 d，同时其下方的结缔组织也开始表达desmin；此外，从第4 d起，管足肌肉及管足表皮层开始表达myogenin，且该表达一直持续到创伤后的第20 d；而第8 d起，步带板肌肉也出现了myogenin的表达，此表达一直持续到第14 d；从第14 d起，体腔上皮也出现myogenin表达，且一直持续到第20 d。

The expression of CD44 was strong positive in stratum intermedium at the bell of differetiational stage, bell of secretory stage, and bell of maturative stage of mouse tooth germ.

在钟状期CD44在口腔上皮、牙板上皮强阳性表达；外釉上皮、星网状层、成牙本质细胞弱阳性表达；分泌期的成釉细胞和牙囊阳性表达。
