When the subject is stem cell research, the term embryo is not only ethically charged, but hard to define.
Now, University of Pennsylvania researchers have stretched the definition even further. In studies with mice, they created embryos using genetic material from only one parent.
This dead-ended the embryos development, but not before the organisms reached the stage where they contained embryonic stem cells the precious precursors of all types of specialized cells. In a first-of-its-kind experiment, these embryonic stem cells were used to reconstitute the blood of adult mice whose own blood cells were destroyed by radiation. The study, published last month in the journal Genes & Development, is another step forward for the emerging field of regenerative medicine. If the same approach works in humans a big if then patients could be given stem cell treatments that their immune systems would not reject.
The question: Would you participate in a medical trial using blood created in this fashion? |
