Bovine placental lactogen activity is shown by immunogold electron microscopy to be restricted to the granules and the Golgi body from which they form in the bovine fetal trophectodermal binucleate cell, and granules of similar size and staining reaction in trinucleate "giant" cells found in the maternal uterine epithelium throughout pregnancy. These results support the hypothesis that a fetal binucleate cell forms a maternal giant cell by migration to and fusion with a uterine epithelial cell.
免疫金电子显微镜显示，牛胎盘催乳素活性局限于牛胎儿滋养外胚层双核细胞中的颗粒以及形成这些颗粒的高尔基体，在整个孕期母体子宫上皮中发现的三核“巨型”细胞中也存在大小和染色反应相似的颗粒。这些结果支持了这样一种假说，即胎儿双核细胞通过迁移至子宫上皮细胞并与之融合而形成母体巨型细胞。
