The statement on Thursday comes amid a growing debate over the use of powerful new gene editing tools in human eggs, sperm and embryos, which have the power to change the DNA of unborn children.

Using the gene - editing tool CRISPR - Cas9 to turn off certain genes in a mouse zygote as well as other new techniques to enrich the pluripotent stem cells of a rat, the group managed to grow various rat organs (a pancreas, heart, and eyes) in a mouse embryo.

A related area of problems arises in connection with the probable increase of organ transplants, the use of artificial bodily parts, and the probability of growing human embryos in the laboratory.

With the introduction of new technology and the growing use of IVF, people needed a way to distinguish between women who were acting as traditional surrogates from those who became pregnant for intended parents through IVF and embryo transfer.

You can, however, position yourself for the best possible outcome by finding a highly effective IVF team (look at www.sart.org for best pregnancy rates in your area) that will work with you to diagnose the problem (look for good two - way communication between the patient and clinic), grow and find the best embryos to transfer (look for a good lab that uses modern tools) and helps you optimize your fertility before you even get started (good physician practice).

Normally, clones are grown in culture used for embryos, and few clones flourish.

Benjaminson and his team have extracted stem cells from fish embryos and used them to grow muscle cells by stimulating them electrically, mechanically, hormonally and nutritionally.

To show their program's promise beyond plant roots, the researchers also used it with a different microscope to watch groups of cells move around in growing zebrafish (Danio rerio) embryos.

Using stem cells from the resulting embryos, Wakayama and his team were able to create clones that grew into fertile adult mice.

A key difference, however, is that Dolly's donor cell came from adult udder cells growing in lab dishes (see ScienceNOW, 24 February), while the donor cells used to create the monkey clones came from early embryos.

Just as in the first report, the researchers used embryos that have three copies of each chromosome and would not grow into a baby if implanted in a uterus.

This means that scientists may have a new starting point from which to grow human tissues — without using embryos.

Instead, NIH had seen «indications» that «scientists are considering exploring the use of human pluripotent cells in early stage animal embryos,» including to grow human tissues or organs.

This must be accomplished by using a process known as germ - line transmission, where the primordial germ cells (PGCs) of an early embryo are edited, grown in cultures, and then reproductively transmitted through surrogate host parents to generate live, engineered birds.

He and the Vereide Group grow precursors of human arterial cells, build colonies of dendritic cells (cells which can alert the rest of the immune system to the presence of a tumor), and use chick embryos to study the formation of early tissue layers for a possible future in which complex tissues, or even organs, can be grown to replace diseased, wounded, or malfunctioning ones.

Scientists at the University of Cambridge have managed to create a structure resembling a mouse embryo in culture, using two types of stem cells — the body's «master cells» — and a 3D scaffold on which they can grow.

Using mouse embryos, we traced individual cells as they grew from the early embryo to determine the exact moment some of these cells start to signal they will become heart cells.

«Our method not only uses soluble factors that guide kidney development in the embryo but, by growing and differentiating stem cells on extracellular matrix components that are also contained in the membrane separating the glomerular blood and urinary systems, we more closely mimic the natural environment in which podocytes are induced and mature,» said Musah.

In 2013, Peterson and his colleagues Joanna Yeh and Keith Joung were first to use the new technology to engineer a new strain of animal — a zebra - fish missing the GSK3ß gene, which encodes an enzyme involved in energy metabolism and the development of cell and body structures as an embryo grows.
