有证据支持海胆胚胎的透明层和作为含胶原的细胞外基质的重新聚集细胞的分类。钌红染色显示存在条纹状纤维样结构、致密球状体、晶格结构和丝状物质。胶原酶消化导致纤维状结构消失;透明质酸酶处理导致其他基质成分减少，但不影响纤维状结构。透明层维持胚胎的完整性，也参与细胞外基质的功能之一的形态发生。
Evidence is given to support the classification of the hyaline layer of sea urchin embryos and reaggregating cells as a collagen-containing extracellular matrix. Ruthenium red staining shows the presence of striated fibril-like structures, dense spheroids, crystalline lattice structures and filamentous material. Collagenase digestion causes disappearance of the fibril-like structures; hyaluronidase treatment causes a diminution of other matrix components, but does not affect the fibrillar structures. The hyaline layer maintains the integrity of the embryo and is also involved in morphogenesis, which are among the functions of extracellular matrices.
