Pediatric Cardiology, 2004
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.

Embryology was a subject that inspired great cross-disciplinary discussion in antiquity, and Plato’s Timaeus made an important contribution to this discussion, though Plato’s precise views have remained a matter of controversy, especially regarding three key questions pertaining to the generation and nature of the seed: whether there is a female seed ...

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 ...
