Book Description
The Cell: Biochemistry, Physiology, Morphology, Volume I focuses on the advancements of processes, techniques, and approaches used in studies on the structure and functions of cells. The selection first offers information on the optical methods in cytology, fixation and staining, and autoradiography. Discussions focus on microscopical analysis, techniques related to autoradiography, staining for electron microscopy and light microscopy, fixation, electron microscope in cytology, and X-ray microscopy of cells. The text then takes a look at the quantitative microscopical techniques for single cells and quantitative microchemical techniques of histo- and cytochemistry. The manuscript ponders on micrurgical studies on living cells, isolation of subcellular components, and "tissue culture," cellular autonomy, and cellular interrelations. Topics include standardization procedures, factors influencing the choice of isolation procedure, future applications and extensions of micrurgy, and applications of micrurgy to the study of living cells. The effects of radiations on cells, acquisition of biological specificity, and nucleocytoplasmic interactions in eggs and embryos are also discussed. The selection is a dependable reference for researchers interested in pursuing further studies on the biochemistry, physiology, and morphology of cells.

Book Description
The progressive changes which occur during the life history of an individual metazoon are summed up under the term development. The adult multicellular organism differs from its early developmental stages by its size, shape, proportions, and by its parts having gradually acquired different structural and functional properties. Accordingly, several main processes involved in development, whose classification is a matter of convention, may be delimitated. Differentiation is considered one of the most important of them. In the broader sense of the word, the term differentiation is used for describing transformations, through which heterogeneity-at all levels (macroscopic, microscopic, submicroscopic)-arises or increases. The basic component of the wider phenomenon of differentiation is differentiation of cells, so-called cytodifferentiation. What is cytodifferentiation? In the course of ontogeny, the cells, starting with the fertilized ovum, via the blastomeres of the segmenting ovum and the germ layer cells, right to the differentiating and fully differentiated cells of tissues and organs, gradually acquire new properties which make them different both from a morphological and functional point of view. All changes involved in this process come under the term cytodifferentiation. Differentiation of cells (though not of all kinds of cells) continues throughout the entire life of the individual, but reaches its maximum at the embryonic period when it becomes the chief feature of development.

Book Description
This volume summarises our present knowledge of inductive interaction during early development of various groups of chordates. Embryonic development is mainly epigenetic, that is, each embryo arises through gradual organisation and emergence of its constituent parts and not by the unfolding of preformed structures. Development as far as the full development of the 'body plan' in the embryo is described. At the beginning of development, there is only very restricted spatial diversity, but as development proceeds the interaction of the different parts leads to ever-increasing spatial complexity of the developing embryo. Interaction starts between the different cell organelles of the oocyte and the, spermatozoon; it continues without interruption between the different parts of the very early embryo and also between the different tissues and organ anlagen of the developing embryo. The new hypothesis as to the nature of the inductive interaction, which is postulated here, is in good agreement with the experimental evidence presented and opens new possibilities for fruitful research into this basic concept of embryonic development.
