Schools for Health and SustainabilityAs early as 1896, . stated that embryogenesis commences during oogenesis. Much evidence now exists suggesting that at least in invertebrates and lower vertebrates the information controlling early embryonic development is programmed during oogenesis (see reviews by ., 1968; . and ., 1972; ., 1972; ., 1972; . et al., 1973a).

Chromosomal Anomalies in Early Spontaneous AbortionDuring the first half of the century anatomical studies of human spontaneous abortions have demonstrated the importance of abnormalities in the development of the conceptus, and, beginning in 1963, various studies have demonstrated the high frequency of chromosomal anomalies in these abortuses.

Oocyte Maturation and Paternal Contribution to the Embryo in Mammalscentrioles, which in somatic cells duplicate themselves, are of particular interest. The developmental changes of some organelles will be discussed under normal and certain pathologic conditions. The more recent findings of virus-like “A” particles will also be presented.

FLAGR

Embryo Transfer Technique and Action of Drugs on the Preimplantation Embryoy depends on the number of cells killed or seriously affected: above a certain proportion, the embryo dies, below that figure, the remaining cells multiply to replace those lost and subsequent development is essentially normal.

Organ Culture in Teratologyts. In teratology, the method may also eliminate some of the difficulties and shortcomings of epidemiological and in vivo studies, but so far it has found only a limited number of applications in this field. Cell culture methods have recently become indispensable in diagnostic teratology but their u
