Book 1979gators to study cytology without the aid of their eyes. The present book makes us realize once more that morphology is the science of structure and shape and that its aim is not to colJect pictures but to understand them. It is true that microscopic observation, even when made with the electron micr

Introductionell formation in man and other mammals were the microscope and cytochemical techniques. In the subsequent decade use was made of the availability of radioactive nuclides and the dynamics of blood cell formation and turnover were quantitated, notably by the introduction first of radioactive iron, the

Diffuse Hemopoiesistiation of hemopoiesis in extraembryonic sites (yolk sac, chorion, body stalk), as well as in intraembryonic areas, as seen in our material. The presentation of our findings here is confined mainly to the early development of blood cells in the extraembryonic mesenchyme, and in contact with endoderm

This progress is primarily due to the introduction of new techniques which allow functional rather than anatomic studies: labeling techniques have made possible the study of celJ kinetics from birth to death of a celJ: culture techniques (both in vivo and in vitro) have made it possibl

Electron microscopic photographs are used to demonstrate fine morphological details of the relationship between hemopoietic cells and yolk sac structures. In the embryo, we describe hemopoietic cells present in the loose connective tissue outside organs.
