Blastogenesis: Normal and Abnormal

An understanding of human developmental biology, both normal and abnormal, cannot progress without the alliance of clinical medicine with research in comparative morphology and embryology, teratology, developmental genetics, molecular biology and pathology. Blastogenesis, the developmental stage leading up to uterine implantation, is a particularly important stage of embryogenesis for study because abnormalities of blastogenesis tend to be severe, multiple and frequently lethal, thus affording geneticists and dysmorphologists an opportunity to study genetic defects in early development. In this work, an international group of human and medical geneticists, human developmental biologists and dysmorphologists present results of molecular, chromosomal, morphological and clinical studies.
