“…As demonstrated by Castro-Claros et al ( 2021 ), Ca 2+ -ions play an important role in the attachment of muscles in bivalves. This suggests that the richness in calcium carbonate made the part of the muscle that was closest to the shell more resistant to decay and thus increased the likelihood of becoming phosphatized.…”

“…It is also conceivable that local conditions within the closed shell were more important than the position of the redox boundary in the sediment and favoured phosphatisation. In addition, due to the proximity to the muscle insertion, we suggest that the resistance to decay of this part of the muscle is linked with the presence of raised levels of Ca 2+ -ions(Castro-Claros et al, 2021 ).…”

“…The adductores are usually differentiated in two parts that correspond to two different functions: (1) quickly contracting to close the valves under threat (quick muscle; fast, strong and short) and (2) keeping the valves closed firmly (catch muscle; slow, continuous, e.g., Bowden, 1958 ; Millman, 1967 ; Chantler, 2006 ; Simone, 2019 ; Eggermont et al, 2020 ; Castro-Claros et al, 2021 ). Accordingly, these muscle fibres can be differentiated functionally and morphologically into striated muscular fibres and smooth fibres.…”

“…Accordingly, these muscle fibres can be differentiated functionally and morphologically into striated muscular fibres and smooth fibres. Their attachment to the shells is usually very strong (Castro-Claros et al, 2021 ), reflecting their importance in protecting the animal. Because of the required strength of this connection, the basal part of the adductors might become fossilized more easily than other soft tissues.…”

Soft-tissue preservation in molluscs is generally rare, particularly in bivalves and gastropods. Here, we report a three-dimensionally preserved specimen of the limid Acesta clypeiformis from the Cenomanian of France that shows preservation of organic structures of the adductor muscles. Examination under UV-light revealed likely phosphatisation of organic remains, which was corroborated by EDX-analyses. We suggest that the parts of the adductor muscles that are very close to the attachment are particularly resistant to decay and thus may be preserved even under taphonomic conditions usually not favouring soft-tissue fossilisation.

“…The authors observed that during mineralization of the myostracum, mantle cells are not in contact with the myostracal shell, while when the ostracum and the hypostracum are mineralized, mantle cells are directly adjacent to the shell. Castro-Claros et al (2021) suggest that two modes of shell secretion are in operation in both these bivalves: (1) Ca transport by vesicles at myostracal prism formation and (2) mineralization in direct contact with mantle cells at ostracum and hypostracum formation. Thus, the above mentioned bivalves utilize, at least, two different mineralization processes when they form their shell.…”

The architecture of Recent brachiopod shells: diversity of biocrystal and biopolymer assemblages in rhynchonellide, terebratulide, thecideide and craniide shells

Biological hard tissues are a rich source of design concepts for the generation of advanced materials. They represent the most important library of information on the evolution of life and its environmental conditions. Organisms produce soft and hard tissues in a bottom-up process, a construction principle that is intrinsic to biologically secreted materials. This process emerged early on in the geological record, with the onset of biological mineralization. The phylum Brachiopoda is a marine animal group that has an excellent and continuous fossil record from the early Cambrian to the Recent. Throughout this time interval, the Brachiopoda secreted phosphate and carbonate shells and populated many and highly diverse marine habitats. This required great flexibility in the adaptation of soft and hard tissues to the different marine environments and living conditions. This review presents, juxtaposes and discusses the main modes of mineral and biopolymer organization in Recent, carbonate shell-producing, brachiopods. We describe shell tissue characteristics for taxa of the orders Rhynchonellida, Terebratulida, Thecideida and Craniida. We highlight modes of calcite and organic matrix assembly at the macro-, micro-, and nano-scales based on results obtained by Electron Backscatter Diffraction, Atomic Force Microscopy, Field Emission Scanning Electron Microscopy and Scanning Transmission Electron Microscopy. We show variation in composite hard tissue organization for taxa with different lifestyles, visualize nanometer-scale calcite assemblies for rhynchonellide and terebratulide fibers, highlight thecideide shell microstructure, texture and chemistry characteristics, and discuss the feasibility to use thecideide shells as archives of proxies for paleoenvironment and paleoclimate reconstructions.

Mussel‐Derived Bioadaptive Artificial Tendon Facilitates the Cell Proliferation and Tenogenesis to Promote Tendon Functional Reconstruction

Tendon injuries range from acute‐related trauma to chronic‐related injuries are prevalent and bring substantial pain, functional loss, and even disability to the patients. The management of tendon injuries is tricky due to the innate limited regenerative capability of the tendon. Currently, surgical intervention of tendon injuries with artificial tendons remains the standard of care. However, most of artificial tendons are manufactured with synthetic materials, which possess relatively poor biomimetic characteristics and inadequate inherent biodegradability, hence rendering limited cell proliferation and migration for tendon healing. To address these limitations, this work develops a mussel‐derived artificial tendon based on double‐cross‐linked chitosan modification. In this design, decellularized artificial tendon serves as a natural biomimetic scaffold to facilitate the migration and adhesion of tendon repair cells. Additionally, as the cells proliferate, the artificial tendon can be degraded to facilitate tendon regeneration. Moreover, the chitosan cross‐linking further enhances the mechanical strength of artificial tendon and offers a controllable degradation. The in vitro and in vivo experimental results demonstrate that mussel‐derived artificial tendon not only accelerate the tendon functional reconstruction but also enable harmless clearance at postimplantation. The finding provides a promising alternative to conventional artificial tendons and spurs a new frontier to explore nature‐derived artificial tendons.
