同源异型盒基因Emx在人胎盘绒毛膜中的扩增

A Homeobox Gene Emx is Amplified in Human Placenta Chorionic Cells

以鹌鹑ＥｍｘｃＤＮＡ片段作为探针，对人胎盘绒毛膜细胞和成人血细胞的基因组ＤＮＡ进行ＤＮＡ印迹分析．结果表明，在人胎盘绒毛膜细胞中Ｅｍｘ基因剂量较成人血细胞高６倍。

Genomic DNA of human placenta chorionic cells and leukocytes were hybridized with Emx probe which is a cDNA fragment including homeobox from quail. The results showed Emx gene dose in human placenta chorioic cells was sixfold more than in leukocytes and indicated Emx gene amplified in human placenta chorioic cells.
