  "abstract": "Echinoderm endoskeleton has a unique trabecular microstructure, called stereom, which can exhibit highly ordered geometries. A striking example of these geometries is the recently discovered \"diamond-type\" stereom, characterized by a diamond triply periodic minimal surface (D-TPMS) and distinguished by exceptional mechanical and structural properties. Despite its promise for engineering applications, the morphogenesis of this microarchitecture remains poorly understood. Here, we applied a multimodal imaging and labeling approach to investigate the developmental processes underlying the formation of the diamond-type stereom in adults of a starfish Protoreaster nodosus. We showed that this stereom type formation of such ordered microstructures remains unresolved. We applied a multi-modal approach to investigate principles of diamond-type stereom morphogenesis. Our results provide key insight into the growth dynamics of this microarchitecture and highlight the essential role of the cytoskeleton, particularly F-actin, in guiding trabecular connectivity and the emergence of minimal-surface geometry, in both periodic and more irregular stereom types.",
