Preimplantation factor (PIF) is a peptide secreted by trophoblast cells prior to placenta formation in early embryonic development. (wikipedia.org)

Human embryos begin to express PIF at the 4-cell stage, with expression increasing by the morula stage and continuing to do so throughout the first trimester. (wikipedia.org)
Tfap2c was undetectable in oocytes and early embryos, and was detectable at relatively high levels in morula and blastocyst IVF embryos. (usu.edu)
The lack of expression in oocytes and donor cells means Tfap2c must be induced in the zygote at the morula stage in properly reprogrammed embryos. (usu.edu)
SCNT embryos expressed Tfap2c at the eight-cell stage, 2 days earlier than control embryos. (usu.edu)
Control embryos first expressed Tfap2c at the morula stage, and at this stage Tfap2c was significantly lower in the SCNT embryos. (usu.edu)

A crucial event in human implantation is when trophoblast cells expressing preimplantation factor invade the uterine wall and found the placenta, an organ that connects maternal blood supply, and along with it, nutrients, to the growing fetus. (wikipedia.org)
Implantation is complete and the placenta is starting to form. (ehd.org)
In the uterus, the morula becomes a blastocyst and eventually burrows into the uterine lining in a process called implantation. (healthline.com)
These well-timed cell divisions are indicative of robust embryo development and are significant indicators of the embryo's potential for successful implantation and further development. (ivfturkey.com)
The inner group of cells will eventually become the embryo, while the outer group will serve as protective and nourishing cells, signaling the embryo's readiness for implantation. (ivfturkey.com)

The blastocyst, a quickly multiplying ball of cells, has begun to penetrate further into the endometrium, the uterus lining. (lostvirtualtour.com)
The ciliary action of the uterine tube transports the zygote to the uterus, during which it undergoes a series of mitotic divisions and transforms into the ball of small cells termed blastomeres. (medscape.com)

The zygote, or fertilized egg, travels down into the uterus and becomes what's called a morula. (healthline.com)
During the first ten to fourteen days after its formation it passes along the uterine tube, towards the uterus, whilst, at the same time, it undergoes the divisions which convert it into a morula. (co.ma)

This process led to the spontaneous assembly of a portion of these cells into an embryo-like structure, which underwent differentiation to represent various components of an embryo, including fetal cells, cells providing nutrients to the fetus, cells directing body development, and cells forming supporting structures like the placenta and umbilical cord. (iasgyan.in)
Initially this cell grows into what is called a Morula, and then a blastocyst, by rapidly dividing to start the process of growing a fetus. (resourceyourhealth.com)
Once the blood supply from the placenta develops at around the 2-week mark, the cells of the fetus start to use oxygen and become aerobic, they start to differentiate into different types of cells, and they have more controlled cell division. (resourceyourhealth.com)
In the in vitro fertilization (IVF) process as well, an embryo may begin to develop but not make it to the blastocyst stage - the first stage at which those cells destined to become the fetus separate from those that will become the placenta. (themasterpiecemom.com)
The blastocyst comprises the inner cell mass (ICM), which gives rise to the three primary germ layers and consequently the fetus, and the trophectoderm (TE), which gives rise to the extraembryonic and placental tissue. (conditionmed.org)
These do not depend on asserting that the zygote/morula/blastocyst/embryo/fetus is not a live human being with the legal status of a person and so reveal why fetuses are unqualified for personhood. (philosophyinaction.com)

The ECFP and EYFP-expressing transgenic ES cells and mice that we have generated provide sources of cells and tissues for combinatorial, double-tagged recombination experiments, chimeras or transplantations. (biomedcentral.com)
But when examined from the viewpoint of the gene and the cell, there are many paths that development can follow, along with the creation of tissues and organs that escalate in form and complexity so rapidly that, paradoxically, while trying to discern the origins of a human life, one can find oneself staring into what seems to be a pathless future. (hachettebookgroup.com)
