Abstract
Zebrafish (Danio rerio) are aquatic vertebrates with significant homology to their terrestrial counterparts. While zebrafish have a centuries-long track record in developmental and regenerative biology, their utility has grown exponentially with the onset of modern genetics. This is exemplified in studies focused on skeletal development and repair. Herein, the numerous contributions of zebrafish to our understanding of the basic science of cartilage, bone, tendon/ligament, and other skeletal tissues are described, with a particular focus on applications to development and regeneration. We summarize the genetic strengths that have made the zebrafish a powerful model to understand skeletal biology. We also highlight the large body of existing tools and techniques available to understand skeletal development and repair in the zebrafish and introduce emerging methods that will aid in novel discoveries in skeletal biology. Finally, we review the unique contributions of zebrafish to our understanding of regeneration and highlight diverse routes of repair in different contexts of injury. We conclude that zebrafish will continue to fill a niche of increasing breadth and depth in the study of basic cellular mechanisms of skeletal biology.

Intact in vivo visualization of telencephalic microvasculature in medaka using optical coherence tomography. Sci Rep 2020; 10:19831.

Abstract
To date, various human disease models in small fish-such as medaka (Oryzias lapties)-have been developed for medical and pharmacological studies. Although genetic and environmental homogeneities exist, disease progressions can show large individual differences in animal models. In this study, we established an intact in vivo angiographic approach and explored vascular networks in the telencephalon of wild-type adult medaka using the spectral-domain optical coherence tomography. Our approach, which required neither surgical operations nor labeling agents, allowed to visualize blood vessels in medaka telencephala as small as about 8 µm, that is, almost the size of the blood cells of medaka. Besides, we could show the three-dimensional microvascular distribution in the medaka telencephalon. Therefore, the intact in vivo imaging via optical coherence tomography can be used to perform follow-up studies on cerebrovascular alterations in metabolic syndrome and their associations with neurodegenerative disease models in medaka.

Gene transfer and mutagenesis mediated by Sleeping Beauty transposon in Nile tilapia (Oreochromis niloticus). Transgenic Res 2013; 22:913-24.

Abstract
The success of gene transfer has been demonstrated in many of vertebrate species, whereas the efficiency of producing transgenic animals remains pretty low due to the random integration of foreign genes into a recipient genome. The Sleeping Beauty (SB) transposon is able to improve the efficiency of gene transfer in zebrafish and mouse, but its activity in tilapia (Oreochromis niloticus) has yet to be characterized. Herein, we demonstrate the potential of using the SB transposon system as an effective tool for gene transfer and insertional mutagenesis in tilapia. A transgenic construct pT2/tiHsp70-SB11 was generated by subcloning the promoter of tilapia heat shock protein 70 (tiHsp70) gene, the SB11 transposase gene and the carp β-actin gene polyadenylation signal into the second generation of SB transposon. Transgenic tilapia was produced by microinjection of this construct with in vitro synthesized capped SB11 mRNA. SB11 transposon was detected in 28.89 % of founders, 12.9 % of F1 and 43.75 % of F2. Analysis of genomic sequences flanking integrated transposons indicates that this transgenic tilapia line carries two copies of SB transposon, which landed into two different endogenous genes. Induced expression of SB11 gene after heat shock was detected using reverse transcription PCR in F2 transgenic individuals. In addition, the Cre/loxP system was introduced to delete the SB11 cassette for stabilization of gene interruption and bio-safety. These findings suggest that the SB transposon system is active and can be used for efficient gene transfer and insertional mutagenesis in tilapia.

Abstract
The global incidence of nonalcoholic steatohepatitis (NASH) is increasing and current mammalian models of NASH are imperfect. We have developed a NASH model in the ricefish medaka (Oryzias latipes), which is based on feeding the fish a high-fat diet (HFD). Medaka that are fed a HFD (HFD-medaka) exhibited hyperlipidemia and hyperglycemia, and histological examination of the liver revealed ballooning degeneration. The expression of lipogenic genes (SREBP-1c, FAS and ACC1) was increased, whereas the expression of lipolytic genes (PPARA and CPT1) was decreased. With respect to liver fatty acid composition, the concentrations of n-3 polyunsaturated fatty acids (PUFAs) and n-6 PUFAs had declined and the n-3:n-6 ratio was reduced. Treatment of HFD-medaka with the n-3 PUFA eicosapentaenoic acid (EPA) mitigated disease, as judged by the restoration of normal liver fatty acid composition and normal expression levels of lipogenic and lipolytic genes. Moreover, medaka that were fed a diet deficient in n-3 PUFAs developed NASH features. Thus, NASH can be induced in medaka by a HFD, and the proportion of n-3 PUFAs in the liver influences the progress of NASH pathology in these fish. Our model should prove helpful for the dissection of the causes of human NASH and for the design of new and effective therapies.

Abstract
Genes encoding spermatogenesis-related substance (eSRSs) show unique expression patterns during spermatogenesis. To analyze their function, we developed a new assay system using gene transfer techniques combined with coculture of the eel germ-somatic cells. First, we investigated the efficacy of in vitro electroporation transfer of gene into germ-somatic cell pellets using green fluorescent protein (GFP) gene. Second, in order to define the function of the eSRSs, we electrophoretically transferred eel spermatogonial stem cell renewal factor (eSRS34) and eel spermatogenesis-preventing substance (eSRS21) genes into germ-somatic cell pellets. Presence of the transferred cDNA was examined by reverse transcription-polymerase chain reaction (RT-PCR). Furthermore, proliferating cells were detected histologically, after labeling with BrdU. Transfer of the eSRS34 gene induced spermatogonial stem cell renewal in the pellets. Moreover, 11-ketotestosterone (11-KT) treatment stimulated the proliferation of spermatogonia, which resulted in the appearance of late type B spermatogonia in the pellets. The proliferation of spermatogonia by 11-KT stimulation was suppressed by transfer of the eSRS21 gene. These results indicate that the transferred eSRS34 and 21genes were functional in the pellets. Thus, an efficient in vitro gene transfer technique for coculture system of germ and somatic cell of Japanese eel was established.

Abstract
Small fish are a popular laboratory model for studying gene expression and function by transgenesis. If, however, the transgenes are not readily detectable by visual inspection, a large number of embryos must be injected, raised and screened to identify positive founder fish. Here, we describe a strategy to efficiently generate and preselect transgenic lines harbouring any transgene of interest. Co-injection of a selectable reporter construct (e.g., GFP), together with the transgene of interest on a separate plasmid using the I-SceI meganuclease approach, results in co-distribution of the two plasmids. The quality of GFP expression within the F0 generation therefore reflects the quality of injection and allows efficient and reliable selection of founder fish that are also positive for the second transgene of interest. In our experience, a large fraction (up to 50%) of GFP-positive fish will also be transgenic for the second transgene, thus providing a rapid (within 3-4 months) and efficient way to establish transgenic lines for any gene of interest in medaka and zebrafish.

Abstract
Japanese medaka (Oryzias latipes) is a freshwater (FW) teleost that is popular throughout the world for laboratory use. In this paper, we discuss the utility of Japanese medaka and related species for studying mechanisms of seawater (SW) adaptation. In addition to general advantages as an experimental animal such as their daily spawning activity, transparency of embryos, short generation time and established transgenic techniques, Japanese medaka have some adaptability to SW unlike the strictly stenohaline zebrafish (Danio rerio). Since other species in the genus Oryzias exhibit different degrees of adaptability to SW, comparative studies between Japanese medaka, where molecular-biological and genetic information is abundant, and other Oryzias species are expected to present varying approaches to solving the problems of SW adaptation. We introduce some examples of interspecies comparison for SW adaptabilities both in adult fish and in embryos. Oryzias species are good models for evolutionary, ecological and zoogeographical studies and a relationship between SW adaptability and geographic distribution has been suggested. Medaka fishes may thus deliver new insights into our understanding of how fish have expanded their distribution to a wide variety of osmotic environments.

Abstract
To develop nuclear transplantation techniques for the medaka Oryzias latipes, nuclei of cultured cells from transgenic fish were transplanted into unfertilized eggs of the orange-red variety of O. latipes, without enucleation, in two experimental series. In the first experimental series, fibroblast cells cultured from the adult caudal fin were used as donors, which carried the green fluorescent protein (GFP) gene driven by the promoter of the medaka elongation factor 1alpha-A gene. Wild-type body color was another donor genetic marker used in this experimental series. In the second experimental series, cells cultured from 6-day-old embryos were used as donors, which carried the GFP genetic marker driven by the promoter of the medaka beta-actin gene. From more than 1000 eggs transplanted in each experiment, a considerable number of nuclear transplants developed to various embryonic stages showing stage- and tissue-specific expression of the donor genetic markers, although the expression was mosaic in many cases. Three and six of the transplanted eggs in the first and second experimental series (0.3 and 0.5%, respectively) hatched, and the hatchlings expressing the genetic markers survived for up to 3 weeks. The chromosome number varied among cells in a single transplant embryo. The results obtained in these experiments may help future cloning efforts in fish.

Abstract
During the past 5 years, green fluorescent protein (GFP) has become one of the most widely used in vivo protein markers for studying a number of different molecular processes during development, such as promoter activation, gene expression, protein trafficking and cell lineage determination. GFP fluorescence allows observation of dynamic developmental processes in real time, in both transiently and stably transformed cells, as well as in live embryos. In this review, we include the most up-to-date use of GFP during embryonic development and point out the unique contribution of GFP visualization, which resulted in novel discoveries.

Abstract
Fertile and diploid nuclear transplants were successfully generated by using embryonic cells as donors in a small laboratory fish, medaka (Oryzias latipes). Embryonic cell nuclei from transgenic fish carrying the green fluorescent protein (GFP) gene were transplanted into unfertilized eggs enucleated by x-ray irradiation. In this study, 1 out of 588 eggs transplanted in the first experiment and 5 out of 298 eggs transplanted in the second experiment reached the adult stage. All of these nuclear transplants were fertile and diploid, and the natural and GFP markers of the donor nuclei were transmitted to the F(1) and F(2) offspring in a Mendelian fashion. This systematic study proves the feasibility of generating nuclear transplants by using embryonic cells from fish as donors, and it is supported by convincing evidence.
