Early Human Embryonic Development: Individuation before Implantation

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...

Hemoglobins of early human embryonic development.

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 ...

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...
