Cord blood appears to provide a better and faster correction of enzyme deficiencies than does adult bone marrow, she said. (dukehealth.org)
Stem cells from cord blood travel to the brain more rapidly than stem cells from adult bone marrow, and cord blood stem cells repair deficiencies in both the central and peripheral nervous systems, said Kurtzberg. (dukehealth.org)

Somatic cell nuclear transfer typically involves the transfer of genomic information from a somatic cell into an unfertilized egg cell whose nucleus has been removed. (the-scientist.com)
Instead of removing the egg genome prior to nuclear transfer, he and his colleagues added the somatic cell nucleus directly to the intact egg. (the-scientist.com)
Cloning entails taking the nucleus - the compartment that contains the DNA - from an adult cell and putting it into an egg from which the original nucleus has been removed. (nih.gov)
The team at OHSU [Oregon Health and Science University], which disclosed its work in a paper published online by Cell, created embryonic stem cells by replacing the nucleus in an unfertilized human egg with the nucleus from a skin cell, then harvesting the resulting stem cells.

In this procedure, the nucleus of an egg cell is removed and replaced by the nucleus of a cell from another adult. (eurostemcell.org)
After being inserted into the egg, the adult cell nucleus is reprogrammed by the host cell. (eurostemcell.org)
The nucleus of an adult somatic cell (such as a skin cell) is removed and transferred to an enucleated egg, which is then stimulated with electric current or chemicals to activate cell division. (who.int)
However, an animal created through this technique would not be a precise genetic copy of the source of its nuclear DNA because each clone derives a small amount of its DNA from the mitochondria of the egg (which lie outside the nucleus) rather than from the donor of cell nucleus. (who.int)
Thus, the clone would be genetically identical to the nucleus donor only if the egg came from the same donor or from her maternal line. (who.int)

Cell therapy involves cultivating or modifying immune cells outside the body before injecting them into the patient. (ajmc.com)

Approximately five days after fertilization the totipotent cells have differentiated and started to form a hollow sphere of cells called a blastocyst. (biomedcentral.com)
After many divisions in culture, this single cell forms a blastocyst (an early stage embryo with about 100 cells) with almost identical DNA to the original donor who provided the adult cell - a genetic clone. (eurostemcell.org)
Instead, embryonic stem cells are isolated from the cloned blastocyst. (eurostemcell.org)

So when I was recently contacted by an earnest and amiable member of a local school board who was concerned about the questionable manner in which the issue of "stem cell" research - both human embryonic and adult - was presented to the high school students in his district in a currently-used science textbook, I agreed to evaluate that section in the text for him. (lifeissues.net)
My edited analysis of the section on "stem cell research" in this science textbook is copied below. (lifeissues.net)
In my opinion there is no question but that the scientific information on stem cell research included in this science text book being used in Illinois schools incorporates some inaccurate scientific facts, and seems to be very partial to the use of human embryonic "stem cell" research.
