FORNICATION AND ADULTERY

In the magazine, The Scientist the article entitled Swapping DNA In The Womb it is stated that: "The findings are the first demonstration of microchimeris in which cells that originated in one individual integrate into the tissues of another—in the human brain, and could have implications for disease." Concluding that: “Knowing cells are in the brain brings home the idea that we’re a little more diverse than we thought we were,” So, conceptually, it may be more appropriate to think of ourselves as an ecosystem rather than a single genetic template.” 

The article then goes on an explains that: "Researchers have suspected that the human brain may harbor microchimeric cells, which are present in other human organs, and previous studies in mice have shown that such foreign cells can break through the blood-brain barrier. But the study, led by Lee Nelson of the Fred Hutchinson Cancer Research Center in Seattle, revealed that microchimeric cells could not only migrate to the brain, but do so frequently: more than 60 percent of autopsied brains contained DNA from another individual. To quantify microchimerism in the brain, Nelson and colleagues selectively looked for a gene found on the Y chromosome in brain sections from 59 female cadavers. 

In total, the researchers found that 37 women harbored such foreign genes in their brains. They also found evidence of cells in the brain, suggesting that microchimeric cells can and do cross the blood-brain barrier."
