Human Endometrial Transcriptomics: Implications for Embryonic Implantation

Human Endometrial Transcriptomics: Implications for Embryonic Implantation.

Human endometrium has been extensively investigated in the search for markers capable of predicting its receptive status. The completion of the Human Genome Project has triggered a rapid development of new fields in molecular biology, the "transcriptomics" being a major turning point in the knowledge acquisition of endometrial receptivity. Based on this, a customized Endometrial Receptivity Arr...

Isolation and culture of human endometrial derived cells as an in vitro model for future implantation studies

Introduction:  Monthly regeneration of endometrium after cyclical mensturation confirmed the ability of specific population of the cells that presence in the basalis layer and undergone consecutive hormonal changes that could prepared the endometrial layer for probable implantation. These cells, known as, stem cell. The aim of this study was the isolation and culture of human endometrial derive...

Physiopathology of human embryonic implantation: clinical incidences.

Embryo implantation consists of a series of events promoting the invasion of the endometrium and then the uterine arterial system by the extra-embryonic trophoblast. In order for this semi-heterologous implantation to succeed, the endometrium has to first undergo a number of structural and biochemical changes (decidualization). The decidua's various constituents subsequently play a role in the ...

Early human embryonic development: individuation before implantation.

Human oviductal gonadotropin-releasing hormone: possible implications in fertilization, early embryonic development, and implantation.

The oviduct is host to gametes and early embryos at a critical point in their lives. It is clear that the interactions of gametes/early embryo with the maternal oviduct in an autocrine and paracrine manner provide a microenvironment that enhances fertilization, early embryonic development, and implantation. Moreover, there is considerable evidence that an extrahypothalamic GnRH may play a subst...
