Syncytiotrophoblast - Wikipedia
The syncytiotrophoblast (from the Greek 'syn'- "together"; 'cytio'- "of cells"; 'tropho'- "nutrition"; 'blast'- "bud") is the epithelial covering of the highly vascular embryonic placental villi, which invades the wall of the uterus to establish nutrient circulation between the embryo and the mother.
合体滋养层 - 百度百科
合体滋养层（syncytiotrophoblast），指的是外层细胞互相融合，细胞间界限消失。 胚泡埋入子宫内膜的过程称为植入，又称着床。 约在受精后第5~6天开始，于第11~12天结束。 在植入的过程中，与内膜接触的滋养层细胞迅速增殖，滋养层增厚，并分化为内外两层。 外层细胞互相融合，细胞间界限消失，称合体滋养层（syncytiotrophoblast）;内层细胞界限清楚，由单层立方细胞组成，称为细胞滋养层。 后者的细胞通过分裂使细胞数目不断增多，并补充融入合体滋养层。 在合体 …
Syncytiotrophoblast: Anatomy, histology and function - Kenhub
2024年3月14日 · Syncytiotrophoblasts are a continuous specialized layer of multinucleated epithelial cells which cover the entire surface of villous trees and chorionic villi (intervillous space of placenta). They are formed by the fusion of trophoblastic cells (syncytium) and play an important role in the growth of the fetus throughout gestation.
Syncytiotrophoblast - an overview | ScienceDirect Topics
Syncytiotrophoblast refers to the outermost layer of all villi in the placenta. It is a true syncytium that is formed by the fusion of mononucleated cells and lacks any lateral cell borders. This layer plays a crucial role in the transfer of nutrients and waste between the mother and the developing fetus, as well as the synthesis of hormones ...
Syncytiotrophoblast - an overview | ScienceDirect Topics
The syncytiotrophoblast (STB); a multinucleated, terminally differentiated, polarised epithelium that covers the entire surface of human placental villi, is one of the largest cell types in human biology (Burton and Fowden, 2015).

外层和子宫蜕膜接触旧称“合体细胞”，今称“合体滋养细胞(syncytiotrophoblast)”。 经更进一步了解正常滋养细胞具有某些独特的生物学特点，这些特点更接近于恶性肿瘤而非正常组织。
Cell Types of the Placenta - Vascular Biology of the Placenta
Villous trophoblasts have two cell populations: undifferentiated cytotrophoblasts and fully differentiated syncytiotrophoblasts. The syncytiotrophoblasts are a continuous, specialized layer of epithelial cells. They cover the entire surface of villous trees and are in …
Syncytiotrophoblast - an overview | ScienceDirect Topics
Arising from the fusion of rapidly dividing villous cytotrophoblasts, the syncytiotrophoblast is a multinucleated cell layer that lacks lateral cell borders (Fig. 1A). This results in the formation of a true syncytium lining the outermost surface of the villous tree, an important protective feature providing a continuous physical barrier [52].
What is the Difference Between Syncytiotrophoblast and …
2023年7月20日 · Syncytiotrophoblast refers to the placental barrier between maternal and fetal blood that allows the exchange of nutrients and gases and also represents the endocrine tissue of the human placenta. In contrast, cytotrophoblast refers to the inner cellular layer of the trophoblast of an embryonic placental mammal that gives rise to the plasmodial ...
Syncytiotrophoblast stress in preeclampsia: the convergence …
Syncytiotrophoblast stress signals in the maternal circulation are probably the most specific biomarkers for preeclampsia. In addition, soluble fms-like tyrosine kinase-1 (mainly produced by syncytiotrophoblast) is the best-known biomarker and is routinely used in …
