Present study using immunohistochemical methods clearly demonstrated the presence of somatostatin-containing cells in the human placenta. These cells were located in the cytotrophoblastic layer, while the layer of syncytiotrophoblasts showed no positive reaction. With the progress of gestation, these immunoreactive somatostatin-containing cells disappeared. It was suggested that somatostatin or somatostatin-like substances play an important role in the maintenance of gestation.
本研究采用免疫组织化学方法清楚地证明了人胎盘中存在含生长抑素的细胞。这些细胞位于细胞滋养层，而合体滋养层未显示阳性反应。随着妊娠的进展，这些免疫反应性含生长抑素的细胞消失。提示生长抑素或生长抑素样物质在维持妊娠中起重要作用。
