Early Human Development

HILL, MARK ANTHONY PhD

Collapse Box

Abstract

Human development in the first 8 weeks is potentially one of the most exciting areas of biologic research. Beyond historic staging of fixed human embryos, it is also one of the least understood. In contrast, detailed information exists for the embryonic period of several other species, from which human development information is extrapolated. This period is also the most sensitive to system abnormalities generated by teratogens. This review combines the human embryo Carnegie stages, available online at UNSW Embryology (http://embryology.med.unsw.edu.au), with teratogen-sensitive information. Integrating this data with current molecular, imaging, and online tools will provide insights to this period.
