Abstract
Despite the attempts that have started since the 1960s, not even a single cell line of marine molluscs is available. Considering the vast contribution of marine bivalve aquaculture to the world economy, the prevailing viral threats, and the dismaying lack of advancements in molluscan virology, the requirement of a marine molluscan cell line is indispensable. This synthetic review discusses the obstacles in developing a marine molluscan cell line concerning the choice of species, the selection of tissue and decontamination, and cell culture media, with emphasis given on the current decade 2010-2020. Detailed accounts on the experiments on the virus cultivation in vitro and molluscan cell immortalization, with a brief note on the history and applications of the molluscan cell culture, are elucidated to give a holistic picture of the current status and future trends in molluscan cell line development.

Abstract
Cell culture provides useful model systems used in a wide range of biological applications, but its utility in marine invertebrates is limited due to the lack of immortalised cell lines. Primary cell and tissue cultures are typically used but remain poorly characterised for oysters, which can cause issues with experimental consistency and reproducibility. Improvements to methods of repeatable isolation, culture, and characterisation of oyster cells and tissues are required to help address these issues. In the current study, systematic improvements have been developed to facilitate the culture of primary cells from adult Pacific oyster tissues and identify novel cell morphologies that have not been reported previously. Cultures analysed by light microscopy, qPCR, and live cell imaging demonstrated maintenance of live, metabolically active Pacific oyster cells for several weeks post-explant. Interestingly, whole hearts dissected from adult oysters were found to continue contracting rhythmically up to 8 weeks after being transferred to a tissue culture system. Mantle tissue explants were also actively moving in the culture system. These improvements in primary cell culture of bivalves may be beneficial for research in ecotoxicology, virology, immunology, and genetic resistance to disease.

Abstract
The lack of shrimp cell lines and difficulty in establishing shrimp cell culture systems, with an appropriate medium is a major concern in the aquaculture sector. The present study attempts to address this issue by developing an in vitro cell culture system from various tissues (hemocytes, heart, lymphoid tissue, hepatopancreas, gill, eye stalk, and muscle) of Penaeus vannamei (P.vannamei) using commercially available L-15 medium. The cell culture medium was formulated using five different media such as HBSCM-1, HBSCM-2, HBSCM-3, HBSCM-4, and HBSCM-5 containing L-proline and glucose with fetal bovine serum (FBS) supplements. Among the different media used, the HBSCM-5 medium with supplements showed good attachment and proliferation of cells with fibroblast-like, epithelioid, round, and adherent cell morphology in hemocyte culture. The same medium was further screened using different tissues to enhance the cell growth. The hemocytes, heart, and lymphoid tissue cells were passaged five times and maintained up to 20 days. Hepatopancreas and gill cells initially showed good morphological features and survived for more than ten days following subculture cells. Eye stalks and muscle cells perished within five days and did not show any unique morphology. The primary hemocyte cells were subjected to species identification, using cytochrome oxidase subunit I (COI) gene. To assess the primary hemocyte cell culture, cells were used for in vitro propagation of white spot syndrome virus (WSSV) and confirmed by the conventional polymerase chain reaction (PCR). Similarly, the primary cells were treated with bacterial extracellular products (ECPs) from Vibrio parahaemolyticus and Vibrio harveyi, to evaluate the cytotoxicity.

Abstract
Bivalves, from raw oysters to steamed clams, are popular choices among seafood lovers and once limited to the coastal areas. The rapid growth of the aquaculture industry and improvement in the preservation and transport of seafood have enabled them to be readily available anywhere in the world. Over the years, oysters, mussels, scallops, and clams have been the focus of research for improving the production, managing resources, and investigating basic biological and ecological questions. During this decade, an impressive amount of information using high-throughput genomic, transcriptomic and proteomic technologies has been produced in various classes of the Mollusca group, and it is anticipated that basic and applied research will significantly benefit from this resource. One aspect that is also taking momentum is the use of bivalves as a model system for human health. In this review, we highlight some of the aspects of the biology of bivalves that have direct implications in human health including the shell formation, stem cells and cell differentiation, the ability to fight opportunistic and specific pathogens in the absence of adaptive immunity, as source of alternative drugs, mucosal immunity and, microbiome turnover, toxicology, and cancer research. There is still a long way to go; however, the next time you order a dozen oysters at your favorite raw bar, think about a tasty model organism that will not only please your palate but also help unlock multiple aspects of molluscan biology and improve human health.

Abstract
In vitro cell culture systems from molluscs have significantly contributed to our basic understanding of complex physiological processes occurring within or between tissue-specific cells, yielding information unattainable using intact animal models. In vitro cultures of neuronal cells from gastropods show how simplified cell models can inform our understanding of complex networks in intact organisms. Primary cell cultures from marine and freshwater bivalve and gastropod species are used as biomonitors for environmental contaminants, as models for gene transfer technologies, and for studies of innate immunity and neoplastic disease. Despite efforts to isolate proliferative cell lines from molluscs, the snail Biomphalaria glabrata Say, 1818 embryonic (Bge) cell line is the only existing cell line originating from any molluscan species. Taking an organ systems approach, this review summarizes efforts to establish molluscan cell cultures and describes the varied applications of primary cell cultures in research. Because of the unique status of the Bge cell line, an account is presented of the establishment of this cell line, and of how these cells have contributed to our understanding of snail host-parasite interactions. Finally, we detail the difficulties commonly encountered in efforts to establish cell lines from molluscs and discuss how these difficulties might be overcome.

Abstract
The present results were obtained in the course of theadjustment to the oyster Crassostrea gigas of atissue culture technique recently developed for themussel Mytilus edulis. With respect to theprotocol originally described, the effects of twomodifications are reported: (1) replacement of chickembryo extract by chicken serum for medium enrichment,and (2) achievement of cultures in rotating tubes(roller drum) in place of stationary condition.Paradoxical results were obtained: whereas takenseparately, each modification exerted a negativeeffect which is statistically significant, combinated,they exerted a high positive effect representing athree-fold increase of the mean metaphase spreadnumber per slide (i.e. 71.5). Hypotheses are proposedto explain the mechanisms involved. It is suggestedthat the two additives work differently and thatcultures with chick embryo extract enriched mediumcould not withstand the condition generated by theroller drum. Conversely, cultures performed withchicken serum enriched medium would be in a betterphysiological state and the roller allow to obtain acell proliferation after only six days of incubation.

Abstract
Heart cells from the clam Ruditapes decussatus were routinely cultured with a high level of reproducibility in sea water based medium. Three cell types attached to the plastic after 2 days and could be maintained in vitro for at least 1 month: epithelial-like cells, round cells and fibroblastic cells. Fibroblastic cells were identified as functional cardiomyocytes due to their spontaneous beating, their ultrastructural characteristics and their reactivity with antibodies against sarcomeric α-actinin, sarcomeric tropomyosin, myosin and troponin T-C. Patch clamp measurements allowed the identification of ionic currents characteristic of cardiomyocytes: a delayed potassium current (I (K slow)) strongly suppressed (95%) by tetraethylammonium (1 mM), a fast inactivating potassium current (I (K fast)) inhibited (50%) by 4 amino-pyridine at 1 mM and, at a lower level (34%) by TEA, a calcium dependent potassium current (I (KCa)) activated by strong depolarization. Three inward voltage activated currents were also characterized in some cardiomyocytes: L-type calcium current (I (Ca)) inhibited by verapamil at 5 × 10(-4) M, T-type Ca(2+) current, rapidly activated and inactivated, and sodium current (I (Na)) observed in only a few cells after strong hyperpolarization. These two currents did not seem to be physiologically essential in the initiation of the beatings of cardiomyocytes. Potassium currents were partially inhibited by tributyltin (TBT) (1 μM) but not by okadaic acid (two marine pollutants). DNA synthesis was also demonstrated in few cultured cells using BrdU (bromo-2'-deoxyuridine). Observed effects of okadaic acid and TBT demonstrated that cultured heart cells from clam Ruditapes decussatus can be used as an experimental model in marine toxicology.

Abstract
In this study, we established and characterized a long-term primary mantle tissue culture from the marine pearl oyster Pinctada fucata for in vitro investigation of nacre biomineralization. In this culture system, the viability of mantle tissue cells lasted up to 2 months. The tissue cells were demonstrated to express nacre matrix proteins by RT-PCR, and a soluble shell matrix protein, nacrein, was detected in the culture medium by Western blot analysis. On the other hand, 15 days after initiating culture, a large amount of calcium deposits with major elements, including calcium, carbon, and oxygen, were generated in the mantle explants and cell outgrowth area. The quantity and size of calcium deposits increased with the prolonged cultivation, and their location and nanogranular structure suggested their biogenic origin. These calcium deposits specifically appeared in mantle tissue cultures, but not in heart tissue cultures. Taken together, these results demonstrate that the mantle tissue culture functions similarly to mantle cells in vivo. This study provides a reliable approach for the further investigation on nacre biomineralization at the cellular level.

Abstract
The main objective of the present work was to evaluate with a quantitative approach the effects of different chicken serum (CS) concentrations in the medium used for mussel mantle tissue culturing. Our results showed that a CS level of 20% was optimal. Under these conditions, the cultures reached a maximum mean number of mitotic figures per slide exceeding widely 100. Cultures were also achieved to test whether CS must be heat treated to inactivate complement components before use for medium enrichment. We demonstrated that heat inactivation did not significantly change the promoting activity of the CS. Finally, the growth-stimulatory properties of CS were compared to those of fetal calf serum (FCS). The best results were obtained with 30% FCS. The difference with 20% CS was not statistically significant, but the FCS yielded a much higher level of polyploid metaphases than the CS. Since it had no adverse effect such as polyploid metaphases induction, was readily commercially available and relatively less expensive than other additives, CS at the concentration of 20%, without heat-decomplementation, is routinely used as growth medium supplement for mussel mantle cell culturing in our laboratory. Even though our primary cultures do not have the potency of continuous cell lines, it is possible to use such cultures for in vitro experiments.

Abstract
Cell characterization of primary cultures in vertebrates is well established but not in marine invertebrates. This fact is hampering advances in the development of tissue cultures from this species. In the present study, a panel of antibodies to structural proteins, stress proteins, oncogenes and proliferation antigens, developed against mammalian antigens, were tested in paraffin sections of the crustacean Pandalus borealis tissues. Several tissues were analysed: hepatopancreas, gills, ovaries, epithelium under the cuticle and abdominal muscle. Specific antibodies to crustacean proteins are not commercially available. The immunocytochemical results show that antibodies to human epitopes cross-react with antigens in the crustacean Pandalus borealis indicating that some cellular proteins are highly conserved in evolution. Cytokeratin, proliferating cell nuclear antigen, ras and p-glycoprotein were detected by immunocytochemistry in Pandalus borealis. No immunoreactivity for Ki-67 and metallothionein was observed. This system can help in validation and characterization of invertebrate cultures.

Abstract
Primary cultures of Pecten maximus heart cells, isolated by an enzymatic procedure, were routinely obtained with a high level of reproducibility in a simple medium based on sterile seawater. Cells attached to the plastic substratum without the need to add a special factor. The number of adhering cells gradually increased with the time of culture. Two types of adhering cells were observed: epitheliallike cells and fibroblastlike cells, which were more numerous. The latter cells were identified as myocytes by electron microscopy and immunofluorescent staining. Results obtained by autoradiography, after incorporation of [14C]leucine, [3H]thymidine, and [14C]acetate, confirmed functional activity of the cells. These cultures were maintained viable in vitro during at least 1 mo.

Abstract
Establishment of cell lines from insect and arachnid invertebrates has become routine, whereas other invertebrate taxa have been frustratingly unproductive of cell lines. None is available for any marine invertebrate, despite a strong and well-recognized need for cell lines from species that are important in aquaculture, from parasite vectors and intermediate hosts of parasites, from parasites themselves, from certain biomedical models, and from other species that are pests. Drawing on experiences gained attempting to establish cell lines from molluscs and trematodes and on published and ongoing research with diverse invertebrates, this chapter attempts to anticipate the problems that are likely to be encountered in such endeavors and discusses possible solutions. Criteria to be considered in the selection of basic culture media, temperature, pH, and media additives; approaches that have been developed to yield sterile primary cultures; and factors to consider in decisions about feeding schedules, retention of tissue fragments and nonadherent cells, use of heterologous feeder layers, and other variables are described. Suggestions are made concerning means to objectively score the success of tested variables and means to induce cell replication. The chapter ends with notes on conventional means to characterize cell lines and an account of contemporary efforts to immortalize cells by means of genome manipulation. Enduring success with a single molluscan cell line, transient successes with crustacean and helminth cell lines, and promising developments in transgenesis with invertebrates all lead to the hopeful conclusion that the invisible barrier to cell propagation in historically refractory species will soon be a thing of the past.
