By using the b2 fragment of Quox-1 gene as probe, we have confirmed that the Quox-1 gene homologous sequence exists in the human genome according to the results of Southern blot. Studies on the expression of Quox-1 homologous sequence in early human embryos from 26 to 37 days by means of immunohistoche-mistry lechnigue with Quox-1 protein antibodies showed the spatiotemporal expre- ssion patterns:in 26 days embryo Quox-1 homologous sequence was expressed in many places including neural tube, but 30 days later, tits expression sites were limited to notochord, digestive epithelium, myo-tome, cardiac muscle cell and periderm. The functions in control and regulation of Quox-l gene homologous sequence during the early development of human embryo were discussed.
