Implantation (embryology) - Wikipedia
In humans, following the stage of hatching that takes place around four to five days after fertilization, the process of implantation begins. By the end of the first week, the blastocyst is superficially attached to the uterine endometrium. By the end of the second week, implantation has completed. [11]
A Review of Mechanisms of Implantation - PMC
The process of implantation allows fetal trophoblast cells to invade and migrate into the maternal decidua. By this time, the trophoblasts at the implantation site have formed masses of cytotrophoblasts and syncytiotrophoblasts.

2024年8月29日 · Implantation is a complex process where a blastocyst stage embryo attaches to the receptive endometrium of the mother and pregnancy begins. For this to occur, there must be total synchrony between the embryo and the endometrium.
Implantation and Establishment of Pregnancy in Human and ...
Successful implantation requires a competent blastocyst and a receptive endometrium during a specific window of time during the menstrual cycle to initiate the bilateral communication required for the establishment of a successful pregnancy.
Physiologic Events of Embryo Implantation and Decidualization ...
The process of implantation involves a complex crosstalk between maternal cells and the developing embryo. Different cell types have the potential to secrete miRNAs contained within extracellular vesicles into the uterine fluid to facilitate the maternal-embryo communication.
