They then went on to demonstrate that the stem cell lines originated from the skin cell donors.

Even more remarkable was that each stem cell line genetically matched one of 11 skin cell donors.

For instance, the egg - cell cytoplasm strips off all of the many epigenetic factors which differentiate a genetically restricted donor skin cell from a totipotent zygote.

The OAR proposal uses a variation of therapeutic cloning called altered nuclear transfer (ANT) in which the nucleus of a donor cell (a skin cell, for example), containing the 30,000 genes of the genetic code, is altered in such a way that it produces an epigenetic factor, a protein called nanog.

The neural progenitor cells used were derived from iPSCs (induced pluripotent stem cells), which were in turn derived from donor skin cells.

Hsiao and colleagues carefully gathered skin samples from donors, and then grew the skin cells in culture before converting them into iPS cells using the methods created by Yamanaka.

The scientists removed the DNA - containing nuclei from the eggs and replaced them with DNA from the donor skin cells.

Six weeks later, spheroids from five of the seven donors had coaxed the skin cells around them to start rearranging, forming the telltale shape of a hair follicle, the team reports online today in the Proceedings of the National Academy of Sciences.

And iPS cells may have a particular advantage: Taking a person's own skin cells, say, making them pluripotent, and then using those cells to grow whatever kind of tissue is needed could eliminate the use of debilitating immunosuppressive drugs, which are required when transplanting cells or tissue from a donor.

GVHD is an immune - mediated disease in which donor T cells recognize and attack the histocompatibility - disparate recipient; it involves multiple organs, such as the lung, liver, intestinal tract, and skin (2 — 4).

In the case of the human - cow embryo, the «donor egg» is the cow's egg, and the «patient's cell» could be something like a skin cell.
