Abstract
The basic idea behind the use of 3-dimensional (3D) tools in biomedical research is the assumption that the structures under study will perform at the best in vitro if cultivated in an environment that is as similar as possible to their natural in vivo embedding. Tissue slicing fulfills this premise optimally: it is an accessible, unexpensive, imaging-friendly, and technically rather simple procedure which largely preserves the extracellular matrix and includes all or at least most supportive cell types in the correct tissue architecture with little cellular damage. Vibrating microtomes (vibratomes) can further improve the quality of the generated slices because of the lateral, saw-like movement of the blade, which significantly reduces tissue pulling or tearing compared to a straight cut. In spite of its obvious advantages, vibrating microtome slices are rather underrepresented in the current discussion on 3D tools, which is dominated by methods as organoids, organ-on-chip and bioprinting. Here, we review the development of vibrating microtome tissue slices, the major technical features underlying its application, as well as its current use and potential advances, such as a combination with novel microfluidic culture chambers. Once fully integrated into the 3D toolbox, tissue slices may significantly contribute to decrease the use of laboratory animals and is likely to have a strong impact on basic and translational research as well as drug screening.

Abstract
The precision-cut tissue slices (PCTS) represent a largely used biological model in mammalian research. This ex vivo approach offers the main advantages of in vitro systems, while maintaining the natural architecture of the tissue. The use of PCTS in toxicological research has been proposed for investigating the cellular effects of xenobiotics or bioactive compounds mostly in mammalian models. Their application is increasing also in marine organisms, but still limited to fish. This work validates the use of PCTS in an invertebrate species, the Mediterranean mussel Mytilus galloprovincialis. Intact tissue slices of different thicknesses (300, 350 and 400 μm) were successfully obtained from the digestive gland. The slices maintained the histological integrity and the viability after 6 h and 24 h incubation in culture medium, with some differences depending on the thickness. The enzymatic activities and mRNA levels of catalase and glutathione S-transferase, chosen as model biological endpoints, were measured until 24 h incubation, revealing the functionality of such systems. This work demonstrates the suitability of mussel PCTS for investigating molecular and cellular responses in ecotoxicological research.

Abstract
Over the last 20 years, the zebrafish has become an important model organism for research on retinal function and development. Many retinal diseases do not become apparent until the later stages of life. This means that it is important to be able to analyze (gene) function in the mature retina. To meet this need, we have established an organotypic culture system of mature wild-type zebrafish retinas in order to observe changes in retinal morphology. Furthermore, cell survival during culture has been monitored by determining apoptosis in the tissue. The viability and excitability of ganglion cells have been tested at various time points in vitro by patch-clamp recordings, and retinal functionality has been assessed by measuring light-triggered potentials at the ganglion cell site. Since neurogenesis is persistent in adult zebrafish retinas, we have also monitored proliferating cells during culture by tracking their bromodeoxyuridine uptake. Reverse genetic approaches for probing the function of adult zebrafish retinas are not yet available. We have therefore established a rapid and convenient protocol for delivering plasmid DNA or oligonucleotides by electroporation to the retinal tissue in vitro. The organotypic culture of adult zebrafish retinas presented here provides a reproducible and convenient method for investigating the function of drugs and genes in the retina under well-defined conditions in vitro.

Abstract
Weakly electric teleost fish possess two classes of electroreceptors: tuberous and ampullary organs. Ampullary organs are used for detecting prey, while tuberous organs detect the fish's own electric organ discharges (EODs) and those of conspecifics. EOD frequency varies among individuals within a species and a fish's tuberous receptors are sharply tuned to its own EOD frequency. In young, small fish both tuberous and ampullary afferents innervate only single organs. As fish grow new receptor cells are added to each organ and it divides into two daughter organs. This process continues resulting in numerous organs in a cluster; the afferent nerve innervates all the organs in a cluster. When a patch of skin is removed new skin grows back complete with new receptor organs of both classes. From our studies we have shown that: (1) new organs are found only in the presence of nerve fibres; (2) their morphological development during regeneration is similar to their normal development; (3) organs divide rapidly giving rise to daughter organs until each afferent fibre innervates the correct number of organs for a fish of its size; (4) receptor cells are broadly tuned below the EOD frequency of a given fish and they gradually increase their tuned frequency and sharpness of tuning until they become correctly tuned to that EOD frequency; (5) the correct matching of receptor tuning to EOD frequency occurs in fish in which the spinal cord has been severed or with lesions of the medullary pacemaker nucleus, thereby eliminating the EOD and any possible 'calibration' signal; and (6) basal and capsule cells of receptor organs in the intact skin around the wound divide after skin damage and are a possible source of precursor cells for new receptor organs.

Abstract
The pattern of NADPH-diaphorase expression was studied in the retina and optic tectum of the cichlid fish Tilapia mariae during the first developmental stages. NADPH-diaphorase activity was seen early, at hatching. In the retina a few cell bodies of the retinal inner nuclear layer showed a faint labeling. Scattered labeled cells were found in the stratum periventriculare of the optic tectum, while the optic nerve was unlabeled. Two days after hatching, the number of labeled neurons increased in the inner nuclear layer and a few stained cell bodies were also scattered in the ganglion cell layer. Both the inner and outer plexiform layers showed a diffuse staining and the optic nerve was devoid of labeling. In the optic tectum several positive cells in the periventricular layer, with their dendritic trees extending in the superficial fibrous layer, were found. In 1-month-old Tilapia, NADPH-diaphorase staining and nitric oxide synthase immunoreactivity were found to overlap in both the retina and optic tectum. The density of NADPH-diaphorase labeled neurons in the inner nuclear layer of the retina and in the stratum periventriculare of the optic tectum was largely reduced in comparison with 2 days posthatching embryos. These findings indicated an early and transient production of nitric oxide in the retina and optic tectum of Tilapia, suggesting a functional role for nitric oxide in the development of visual structures in aquatic vertebrates.

Abstract
The retina in teleost fish continues to grow throughout much of the life of the animal, in part by the continuing differentiation of new tissue at the retinal margin, an area termed the peripheral growth zone (PGZ) (Lyall, Q J Micros Sci, 1957:98:101-110). We have developed a retinal slice preparation--including the PGZ--from juvenile rainbow trout (Onchorynchus mykiss), a species in which retinal growth is rapid and the PGZ is correspondingly pronounced. The PGZ slice preparation contains a time line of retinal development, with cells at different stages of maturation present side by side. We present evidence that the birth sequence of the various retinal cell types in the PGZ recapitulates the sequence during embryonic development. We also report data on the rate of growth of the PGZ in juvenile trout in vivo. Finally, we have used the PGZ slice preparation to make whole-cell voltage clamp recordings from individual retinal GCs at both early and late stages of maturation. We report that the amplitude of delayed rectifier and A-type potassium currents increases during GC maturation.

Abstract
In the vertebrate central nervous system, the retina has been a useful model for studies of cell fate determination. Recent results from studies conducted in vitro and in vivo suggest a model of retinal development in which both the progenitor cells and the environment change over time. The model is based upon the notion that the mitotic cells within the retina change in their response properties, or "competence", during development. These changes presage the ordered appearance of distinct cell types during development and appear to be necessary for the production of the distinct cell types. As the response properties of the cells change, so too do the environmental signals that the cells encounter. Together, intrinsic properties and extrinsic cues direct the choice of cell fate.

Abstract
We tested the effects of several growth factors on the proliferation and differentiation of cells in the teleost retina which typically become rod photoreceptors to understand their regulation. Using organotypic slice cultures of differentiated teleost fish retinal tissue, we found that insulin and insulin-like growth factor I (IGF-I) stimulate proliferation of rod precursor cells whereas basic fibroblast growth factor (bFGF) does not. In the presence of bFGF, however, a greater proportion of the cells that had divided expressed a rod photoreceptor-specific phenotype than did control slices. This suggests insulin and the related IGF-I can influence the regulation of neuronal cell division whereas bFGF promotes the differentiation of neuronal stem cells into rod photoreceptors in retinal slice culture. These results support the idea that cell division and differentiation are differentially regulated and diffusible factors play a role in this process.

Abstract
Vertical slices of 6-day postnatal (P6) rat retina were cut at a thickness of 100 microns and cultured using the roller-tube technique. After 14-21 days in vitro there was significant distortion of normal retinal architecture, but localized areas of the slices showed the typical pattern of layering of mature retina. The following immunocytochemical markers were used to characterize the different retinal cell types: antibodies against protein kinase C (PKC), calcium binding protein (CabP 28kD), neurofilaments (NF), glia-specific antibodies (GFAP, vimentin), and transmitter-specific antibodies (GABA, TH). The expression of these markers was compared in P6 retina, adult retina, and slice culture. To further characterize the cultured cells, patch-clamp recordings were performed in combination with intracellular injection of Lucifer Yellow (LY). Transmitter- and voltage-gated membrane currents were recorded from morphologically identified neurons. The experiments show that a mammalian slice culture can be used to study differentiation and function of retinal cell types.

Abstract
Regeneration of vertebrate sensory cells can be seen as an extension and elaboration of the process of cellular repair and to understand repair requires knowledge of how cell division and cell fate are determined. To approach these problems, we have developed a slice culture for the teleost retina. Cells continue to divide in the same pattern in this slice culture as they do in vivo as demonstrated with [3H]thymidine labeling. Moreover, cells which divided in culture became retinal cell phenotypes as identified with monoclonal antibodies. Some presumptive rod progenitors in the outer nuclear layer in the center of the retina were also labeled cone-specific, possibly as a regeneration response. These data add to the evidence that cell fate is determined by the environment. This slice preparation will be a useful model system for analyzing putative environmental cues responsible for guiding cell proliferation and differentiation in the fish retina.
