Due to the limited statistical and methodological certainty allowed by biological science, the occurrence of technical errors in biological experiments, the differences between human and animal embryo development, the rapidity by which the cloning procedure produces a totipotent zygote, and the philosophical and theological nature of the question, there is no biological experiment that will prove with moral certainty that a human zygote never exists during the OAR procedure.

Example in point: Opposition to embryonic stem cell / human cloning research: It isn't anti science to oppose treating nascent human life like a corn crop or manufacturing embryos, anymore than it is anti science than the Animal Welfare Act the proscribes what can and can't be done in scientific research with some mammals.

It is our ability to think and reason that makes us human and distinguishes us from all other animals, a piece of tissue, and a baby from an embryo with no measurable brain waves.

For reproductive cloning - which creates animals with an identical genetic make - up to an already existing animal - the embryo must then be transferred to a host body, in which to grow.

Totipotent cells are the most versatile of all stem cells; a single one can develop into an embryo with a placenta, and hence give rise to a fully formed animal — in other words, a clone.

As a result, he and other researchers have begun genetically modifying pig embryos with the hope they will eventually give rise to pigs that contain one or more human organs — the subject of his feature - length article «Human Organs from Animal Bodies.»

When they created MR images of the tadpoles that grew from these embryos, bright spots indicated where the enzyme was active — in half the animal — and the spots correlated closely with standard stains of enzyme activity done by sectioning the tadpole, they report in the March Nature Biotechnology.

Using her new culture system, she joined forces with colleagues to research which cells in an embryo contribute to which parts of the adult animal, a process called fate - mapping.

From embryo cloning, it has led to an adult clone of an adult animal, and then to breakthroughs with additional species.

Xiao compared the fossils with modern embryos and concluded that he was looking not at algae but at something far more breathtaking: embryos of some of the first animals on Earth.

Particularly valuable animals could be cloned from adult cells without the uncertainties of crossing them with other animals or tinkering with embryos.

That and other concerns led the National Institutes of Health to announce in 2015 that it would not fund experiments that put human pluripotent stem cells, those with the ability to morph into almost any kind of tissue or organ, into the early embryos of other animals.

We exploit chick and mouse embryo animal models, combined with live imaging, cell and tissue cultures and molecular approaches.

Origins of Muscle Stem Cells: During development, the embryo has three different tissue types that, together with the germ cells, will make up the animal's entire body.

Jon Hennebold, a researcher at the Oregon National Primate Center, is injecting monkey embryos with CRISPR to breed animals with more genetically precise equivalents of human diseases.

Summary: Extremely powerful genes that govern the shape of an embryo from the earliest stages of development have been tinkered with by nature over the course of evolution to create the enormously wide range of animal forms, scientists report in the August 14, 1997 issue of Nature.
