Mutable collagenous tissues (MCTs) of echinoderms can be regarded as intelligent and dynamic biomaterials, due to their ability to reversibly change their mechanical properties in a short physiological time span. This mutability phenomenon is nervously mediated and involves secreted factors of the specialized ‘juxtaligamental’ cells, which, when released into the extracellular matrix (ECM), change the cohesive forces between collagen fibrils.
