Approximately 3% of newborn babies suffer from congenital anomalies (birth defects), which is a serious burden for patients and their families. Many congenital anomalies are assumed to be caused by the interaction of gene mutations and environmental factors, but the etiology and pathogenetic mechanisms remain to be clarified for most birth defects. In our laboratory, interdisciplinary research approaches are being undertaken to elucidate the causes and pathogenesis of birth defects and to attempt to identify some preventive measures.
Research and Education
The professor Yamada is also in charge of Congenital Anomaly Research Center, Kyoto University Graduate School of Medicine. This Center has the largest collection of human embryo specimens in the world comprising of over 44,000 therapeutic abortuses. Most of the specimens are between the 3rd and 8th week following fertilization, which is the critical period of teratogenesis. In the Kyoto Collection of Human Embryos, an appreciable number of malformed embryos are included, which provide a unique opportunity to study the early stages of abnormal morphogenesis. A variety of research projects are at present being undertaken on the embryo collection.
