Perspectives on fetal lung development
Lung, 1981Lung development requires carefully regulated coordination of anatomic, physiologic, and biochemical processes. The result of these maturational events must be an organ having an adequate surface area, sufficient vascularization, and the metabolic capability to sustain oxygenation and ventilation during the neonatal period.

Fetal Prostate Growth and Development
Pediatric Pathology, 1990Normal fetal and newborn prostates were studied to evaluate growth patterns, histogenesis, and secretory activity. Whole cross-sectioned prostates harvested from 107 necropsies of fetuses and newborns ages 20 weeks gestation to 1 month of age were used.

Glucocorticoids and fetal lung development
Journal of Steroid Biochemistry, 1977Abstract Acceleration of fetal lung development by administration of glucocorticoid hormones has been demonstrated in a number of mammalian species. Dexamethasone 10 −5 M significantly depressed protein content per explant in the presence and absence of insulin.

Iron and copper in fetal development
Seminars in Cell & Developmental Biology, 2011Copper and iron are both essential micronutrients. Because they can both accept and donate electrons, they are central to many energy dependent chemical reactions. For example, copper is a critical part of ferroxidase enzymes ceruloplasmin, hephaestin and zyklopen, as well as enzymes such as dopamine-β-monoxygenase, while iron is part of the catalytic ...

THE FETAL AND NEONATAL DEVELOPMENT OF TWINS
Pediatrics, 1964The current study presents prenatal data on body, organ and placental development of monovular and diovulvar twins. Most twin measurements match mean values for single gestations through the 24th gestational week. Subsequently, growth of body and organs is not as rapid in twins as in single-born infants.

The Development of Human Fetal Hearing
Science, 1983Blink-startle responses to vibroacoustic stimulation were monitored ultrasonically in human fetuses of known gestational age. Responses were first elicited between 24 and 25 weeks of gestational age and were present consistently after 28 weeks.

Fetal development in experimental uremia
Virchows Archiv A Pathological Anatomy and Histology, 1977Uremic women on hemodialysis with metabolic bone disease (hyperparathyroidism, osteomalacia resulting from defective vitamin D metabolism) and anemia (erythropoietin deficiency) are known to give birth to infants without bone disease or anemia. Therefore, skeletal development (enchondral and desmal bone formation) and hepatic erythropoiesis were ...

Fetal development of the human amygdala
Journal of Comparative NeurologyAbstract The intricate development of the human amygdala involves a complex interplay of diverse processes, varying in speed and duration. In humans, transient cytoarchitectural structures deliquesce, leading to the formation of functionally distinct nuclei as a result of multiple interdependent developmental events.

Fetal chemoreception: a developing story
Reproduction, Fertility and Development, 1996The central and peripheral chemoreceptors are critical to the efficient uptake and delivery of oxygen and the removal of carbon dioxide after birth. However, the importance and activity of fetal chemoreception has been questioned, since oxygen uptake and carbon dioxide removal are not regulated in the lungs in the fetus.
