The non-receptive uterine luminal epithelium forms an intact polarised epithelial barrier that is refractory to blastocyst invasion. During implantation, organised dismantling of this barrier leads to a receptive state promoting blastocyst attachment. Claudins are tight junction proteins that increase in the uterine epithelium at the time of implantation.(More)
At the time of implantation, uterine luminal epithelial cells undergo a dramatic change in all plasma membrane domains. Changes in the basolateral plasma membrane at the time of implantation include progression from smooth to highly tortuous, as well as a loss of integrin-based focal adhesions. Another aspect of the basolateral plasma membrane that has not(More)
The plasma membrane of uterine epithelial cells undergoes a number of changes during early pregnancy. The changes in the basolateral membrane at the time of implantation in particular change from being smooth to highly tortuous in morphology, along with a dramatic increase in the number of morphological caveolae at this time. The major protein of caveolar(More)
The non-receptive uterine luminal epithelium forms a polarised epithelial barrier, protective against potential pathogenic assault from the external environment and invasion by the blastocyst. However, during the window of implantation, the uterine luminal epithelial cells (UECs) transition to a receptive state by dismantling many of their intercellular and(More)
