During the first 20 days of development, the human embryo has no cardiovascular structure. Over the next month, the heart and great vessels complete their development and look very much like they will at full gestation. This amazing process transforms isolated angiogenic cell islets into a complex, four-chambered structure.

Until today, several theories have been developed to explain the occurrence of common foregut malformations as esophageal atresia and tracheoseophageal fistula. Most researchers believe that these malformations are the result of an impaired process of septation of the early foregut.

Reptiles (lizards, snakes, turtles and crocodylians) are becoming increasing popular as models for developmental investigations. In this review the leopard gecko, Eublepharis macularius, is presented as a reptilian model for embryonic studies. We provide details of husbandry, breeding and modifications to two popular histological techniques (whole ...

In most textbooks of embryology and pediatric surgery, the puzzling spectrum of midgut "malrotations" is explained by an "impaired" process of rotation of the midgut. However, this "process of rotation" is explained in a rather schematic way and aims more to explain pathologic findings whereas detailed embryologic investigations are still rare in this ...

Prenatal development, characterized by intensive cell proliferation, cell differentiation and cell migration, shows a high radiosensitivity. Therefore, radiation exposure of embryos and fetuses is of great concern for radiological protection and human health.

A histologic study was made of 50 human fetal pituitaries of gestational ages 5–40 weeks with the aid of the aldehyde thioninperiodic acid Schiff-orange G stain. Though pituitary basophils became apparent at 9 weeks, it was only at 13 weeks' gestation that some of them took up the aldehyde thionin stain. The appearance of the primitive thyrotroph at 13

The embryology of the diaphragm
Seminars in Pediatric Surgery, 2011Despite the progress in prenatal diagnosis and intervention as well as postnatal therapeutic strategies, congenital diaphragmatic hernia (CDH) is still associated with a meaningful mortality because of the induced pulmonary hypoplasia. An essential key in understanding the pathogenesis of CDH is the underlying embryology, which has been neglected ...

Development of the sternum during the growth of the embryo is described. Anterior body wall defects in the thoracic region may be severe, leading to ectopia cordis, or mild, as in skin-covered sternal clefts. The embryologic basis for other sternal abnormalities, such as pectus excavatum and pectus carniatum, is not clear; however, abnormalities of rib
