Ultrastructural studies on the collagen of the marine sponge Chondrosia reniformis Nardo.
The ultrastructure of isolated fibrils of Chondrosia reniformis sponge collagen was investigated by collecting characteristic data, such as fibril thickness, width, D-band periodicity, and height modulation, using atomic force microscopy (AFM) and transmission electron microscopy (TEM). Therefore an adapted pre-processing of the insoluble collagen into homogeneous suspensions using neutral buff...
متن کاملMechanical adaptability of a sponge extracellular matrix: Evidence for cellular control of mesohyl stiffness in Chondrosia reniformis Nardo.
The marine sponge Chondrosia reniformis Nardo consists largely of a collagenous tissue, the mesohyl, which confers a cartilaginous consistency on the whole animal. This investigation was prompted by the incidental observation that, despite a paucity of potentially contractile elements in the mesohyl, intact C. reniformis stiffen noticeably when touched. By measuring the deflection under gravity...
