Abstract:
Abstract Post-embedding immunocytochemistry involves carrying out immuno cytochemical techniques on tissue which has been fixed, dehydrated, and embedded in a material suitable for cutting sections for subsequent light or electron microscopy, (e.g. wax, celloidin, resin). It is beyond the scope of this chapter to discuss all the available techniques and so it will concentrate on post-embedding methods applied to material which has been prepared in the conventional manner for electron microscopy, including post-fixation with osmium tetroxide and embedding in epoxy resin. Many antigens do not survive this treatment; their antigenicity may be affected by osmium tetroxide treatment, by resin infiltration (possibly due to interactions of the antigen with epoxy groups), and by heat (1-3). However, amino acids such as -y aminobutyric acid (GABA), glutamate, aspartate, taurine, glycine, and glutamine have been successfully localized using these methods (4).

Abstract:
This chapter addresses immunocytochemical techniques and their role in diagnostic histopathology. Immunocytochemistry (ICC) is used as a second string of investigations following conventional staining techniques. The role of the primary investigations is to demonstrate the morphological appearance of the cell and tissue architecture. This enables identification of the disease process, and in a substantial number of cases is adequate to formulate a final diagnosis. However, the demonstration of morphological detail alone may not enable a diagnosis to be made in all cases, and in such instances an assessment of the cell marker (antigen) expression on the cell membrane, cytoplasm, or nucleus is required. This provides selective information that can be used to define certain cell types. This is the role of ICC, which, in some instances, is closely allied to molecular diagnostics. The chapter then details the process of tissue preparation and antigen retrieval.

Abstract:
Abstract Many types of cancer and genetic disease are characterized by chromosomal abnormalities. These can be detected by conventional cytogenetics, which involves photographing banded chromosomes on metaphase spreads. Although this is a widely used technique in haematology, oncology, and pre-natal diagnosis, it is a time-consuming process that relies heavily on the skill and experience of the cytogeneticist. In addition, in cancerous cells, the sometimes complex karyotypes encountered mean that such analysis is often extremely difficult. An alternative approach is to prepare a monodispersed suspension of chromosomes, stain with one or two fluorescent DNA dyes, and pass them through a flow cytometer. The intensity of the fluorescence signal from each chromosome is recorded, the values being dependent on their DNA content. In single-colour analysis, a non-base-specific dye such as ethidium bromide is used. Accumulating data from 50000 chromosomes and presenting this as a histo gram of fluorescence intensity produces a distinctive species-specific pattern of peaks. However, not all chromosomes appear as a single peak. An improvement is to use bivariate analysis that exploits the base-pair binding preferences of DNA specific dyes: usually Hoechst 33258 (which has an adenine/thymidine (AT) binding preference) in combination with chromomycin A3 (which has a guanine/cytosine (GC) binding preference). The intensity of staining with these fluorochromes is dependent not only on the DNA content but also on the base composition of each chromosome. The data accumulated can be presented as an isometric plot or, better, as a dot plot or contour map (see Figure 1). The bivariate plot resolves all the human chromosomes as separate peaks, with the exception of chromosomes 9, 10, 11, and 12.

Abstract:
Abstract The use of optical imaging to study biology in animal models and to detect markers of disease in humans provides a window through which we can view features of disease that are either not detectable by conventional approaches or that can be detected more efficiently with optics. Moreover, with optics we can often appreciate patterns in biological processes that would be otherwise overlooked or missed. Because the nuances of disease mechanisms and the subtleties of the response to therapy are key to understanding and resolving disease, imaging has become an essential tool for revealing pathogenic mechanisms and for developing effective therapeutic strategies. Optical imaging tools comprise a key set of approaches for the study of biology in animal models, and are emerging as powerful methods for early disease detection, staging of progression, and assessing response to therapy in the clinic. Sensitive and rapid imaging methods based on the optical properties of tissues or the detection of reporter proteins and dyes provide real-time information that will contribute to our ability to unravel the mechanisms of disease, enable us to intervene with treatment strategies, and allow us to assess therapeutic outcomes. Because optical imaging methods cover a range of scales, with resolutions from microns to centimeters, the preclinical and clinical applications are far-reaching, with great potential for changing the way these studies are performed. The clinical utility of optical imaging, however, is limited to a narrow set of applications in which the depth of penetration of light is sufficient to interrogate the intended target in mammalian tissues. These intended targets could be biological structures or molecules that are intrinsic to the tissue, or exogenous reagents that can label cells or stain tissues. The small number of approved optical contrast agents for human use further confines optical imaging in the clinic to specific application areas. In contrast, in preclinical studies the applications are limitless because the study subjects are typically small laboratory rodents in which many tissues and organs are accessible to optical tools. In addition, the cells and tissues in laboratory animals are amenable to staining with a range of exogenous dyes and may even be manipulated genetically to express optical reporters. Perhaps the greatest impact that optical imaging will have on human health is by providing a greater understanding of mammalian biology and more rapid evaluation of new therapies in laboratory animals.
