[The expression of Quox-1 gene homologous sequence in the development of early human embryos].
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 immunohistochemistry technigue with Quox-1 protein antibodies showed the spatiotemporal expression 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, myotome, cardiac muscle cell and periderm. The functions in control and regulation of Quox-1 gene homologous sequence during the early development of human embryo were discussed.
