evolved to become an essential tool in both basic and clinical research. Use of this instrument has contributed significantly to the formation of new perspectives and concepts concerning cell fine structure. These structural perspectives are now being integrated with specific functional, biochemical

Feature

Structure and evolution of the nucleolus during oogenesisphological information related to the physiological state of the cell. Correlations of nucleolar structure and function during oogenesis can be made on the basis of new formation, in large numbers, intense growth and numerous morphological transformations.

critic

Problems in the analysis of mammalian fertilizationviews of the subject, the most recent of which is an excellent review by Yanagimachi (1). A discussion of experimental systems has been chosen because there is a need to consider the difficulties in comparing experiments on many different systems and interpreting the relevance of experiments carried out on . systems to fertilization in nature.

Ultrastructure of primordial germ cells in the early chick embryokaline phosphatase reactions have been utilized. For example, the PAS staining for glycogen has been effective for the identification of PGCs in chicks (5–11), turtles (4), lizards (12) and humans (13). Alkaline phosphatase activity has been used for identification of these cells in mice (14–18) and humans (19, 20)
