Many clinical studies have established the potential value of certain prostaglandins for the termination of pregnancy at all stages of gestation and for the induction of labor (Anderson and Speroff, 1973). Undoubtedly, the surge of interest in the clinical application of prostaglandins as therapeutic...

This report summarizes recent advances in the understanding of the structure and organization of the microvasculature in developing human skin. Previous observations suggested that the skin contains no blood vessels as late as eight weeks estimated gestational age (EGA). Computer reconstructions, in conju...
Embryonic development In the early germinal stage, three fundamental layers of tissue form the embryo: the endoderm, mesoderm, and ectoderm. The nervous system develops from a segment of the ectoderm, called the neural plate. At 3 weeks of gestation, the edges of the neural plate form neural ...
Knowledge of wild species embryonic development is important for their maintenance in captivity or the wild. The objective of the present study was to characterize the external morphology and define the biometry of greater rhea embryos and fetuses at different stages of development. A total of 41 ...
This study covers the development of Todaro's tendon during human embryonic and fetal periods. The tendon primordium first appears when human embryos attain a CR length of 22 mm, but it only becomes well-defined at 24 mm CR length. The tissue that will form the tendon proceeds exclusively fr...
For this study we used serial sections of 57 human embryonic (n = 30) and fetal (n = 27) specimens from O'Rahilly stages 17–23 and 9–14 weeks, respectively. The following phases in carpal morphogenesis have been established: undifferentiated mesenchyme (stage 17), condensated mesenchyme (...
f, The percentage of zygotes that successfully progressed to the blastocyst stage during in vitro culture. Data are presented as the means ± s.d. from three independent experiments (total number of embryos analyzed: n = 90 for ND, n = 112 for ND + DMOG, n = 95 for ...
In the mouse embryo, most cortical neurons (pyramidal neurons) are born in the VZ via asymmetric division of radial glial cells and migrate along the radial projections of glial cells toward specific regions of the peripheral cortex during the late stage of cerebral cortex development [28]. Our...
