The cellular events that take place during reconstruction of larval forms from dissociated embryonic cells of the starfish are investigated by thick and thin sections. Dissociated cells reaggregate, form an external epithelium (ectoderm), internal epithelial vesicles (endoderm), the blastocoel and the mesenchyme. The internal vesicles continue to fuse until there is only one large one suspended in the centre of the blastocoel. Eventually, the ectoderm invaginates at one or more sites and fuses with the endoderm to form blastopore(s). Special emphasis is placed on the differences in cell behaviour during endoderm-to-endoderm and endoderm-to-ectoderm fusion.
通过厚切片和薄切片研究了海星胚胎解离细胞重建幼虫形态过程中发生的细胞事件。解离的细胞重新聚集，形成外部上皮（外胚层）、内部上皮囊泡（内胚层）、囊胚腔和间充质。内部囊泡持续融合，直到只有一个大囊泡悬浮在囊胚腔中央。最终，外胚层在一个或多个部位内陷并与内胚层融合形成胚孔。特别强调了内胚层与内胚层融合以及内胚层与外胚层融合过程中细胞行为的差异。
