“…Antibodies raised against the histidine-rich protein extracted from granular cells [42] and the stratum corneum [42][43][44] stained both KHG and cornified cells, indicating an immunoiogic homology between the proteins of these two layers (Fig 8). In concert with these observations were the biochemical data which revealed that histidine-rich, basic protein in the keratohyalin granule was a high molecule weight, phosphorylated, polymeric precursor (now called profilaggin [45]) of the immunologically cross-reactive protein in the stratum corneum cell [46][47],…”

S tephen Rothman [1] wrote: "Modern dermatology has been built on the solid pillars of precise macro-and microscopic observation, accurate recording and meaningful interpretation ofthe findings. No natural science can exist without direct observation of natural phenomena, and dermatology has become a great discipline because we have had so many good observers." He went on to state further that "... whereas the immense knowledge acquired by the classical descriptive methods is still rapidly increasing, the application of experimental methods to dermatologic problems is a relatively young and undeveloped approach." These statements acknowledge the importance of observation and description (usually thought of as features of morphology) in clinical dermatology and in descriptive dermatologic research, but were made before he could recognize the value of morphology to experimental studies as well. Unfortunately, Dr. Rothman did not see the remarkable expansion in dermatologic research that has taken place within even the last 20 years, an eta in which descriptive biology and experimental biology are not necessarily separate entities or even parallel concepts. Morphology is simply one of many approaches --sets of tools -that can be used to solve problems in biology.Morphology is often the starting point of an investigation. Understanding the structure of a cell or tissue provides a framework on which other kinds of data can be applied. A morphologic study, however, need not be synonomous with description and qualitative investigation. Many ofthe techniques used by morphologists provide compositional information (presence/absence of a chemical compound) on a structural substrate (location within the cell or tissue) which, in turn, permits interpretation of function. For example, electron microscopic autoradiography can be used to identify the site of incorporation of a radiolabeled amino acid within the tissue and the specific cell and organelle in which it is utilized, or x-ray microanalysis can reveal the elemental composition of parts of cells or different cells within a tissue. Through the use of techniques like morphometry and stereology, morphologic studies can also be quantitative. To continue the example from above, the volume density ofthe radiolabeled organelte can he determined for a cell or tissue by means of selective sampling and prescribed methods of counting, thus allowing for quantitation and statistical analysis when comparing experimental data. Morphology should not have the limited connotation of providing purely descriptive information.The structure and composition of a tissue can provide insight into its function. As stated by Braverman and Braverman [2], "a major aim of biological work is to correlate structure with function in order to understand how tissues work." The goal in the present paper, as indicated by its title, is to support this statement as we review the use of morphologic approaches to understand skin hiology, selecting as an illustration the progress that has been made in understan...

“…Histidine rich proteins, too, have been identified in these granules (Murozuka et al, 1979;Lynley and Dale, 1983). These granular cells get abruptly transformed into comified cells consisting of keratin filaments, interposed between which are keratohyalin derived interfilamentous matrix materials, which serve the function of aggregation of the keratin filaments.…”
