Although some aspects of human embryo development are conserved with those of other species, including the mouse, many aspects such as the timing of reprogramming and occurrence in the absence of transcription, duration of transcriptional silence and identity of genes with modulated expression in the oocyte to embryo transition, appear to be unique. Yet, frequently, the only data available for understanding the programs of early embryo development is that derived from model or agricultural species. We suggest that a specific understanding of basic aspects of human embryo development can affect a two-fold positive impact: 1) We can improve the health of a substantial subset of patients who seek assisted reproduction by improving diagnostics of viable embryo development in the clinic and, 2) we can use the information we gather to improve derivation and diagnosis of pluripotent stem cell lines (including reference or gold-standard human embryonic stem cell (hESC) lines and closely-related induced pluripotent stem cell (iPSC) lines) and their fates in novel basic and clinical applications.

D011247	Pregnancy	The status during which female mammals carry their developing young (EMBRYOS or FETUSES) in utero before birth, beginning from FERTILIZATION to BIRTH.	Gestation,Pregnancies
D011379	Prognosis	A prediction of the probable outcome of a disease based on a individual's condition and the usual course of the disease as seen in similar situations.	Prognostic Factor,Prognostic Factors,Factor, Prognostic,Factors, Prognostic,Prognoses
D011786	Quality Control	A system for verifying and maintaining a desired level of quality in a product or process by careful planning, use of proper equipment, continued inspection, and corrective action as required.

D001755	Blastocyst	A post-MORULA preimplantation mammalian embryo that develops from a 32-cell stage into a fluid-filled hollow ball of over a hundred cells. A blastocyst has two distinctive tissues. The outer layer of trophoblasts gives rise to extra-embryonic tissues. The inner cell mass gives rise to the embryonic disc and eventual embryo proper.
