Note that the article admits that embryos are destroyed in the harvesting of embryonic stem cells. No longer do we see “pre-embryo” or other invented terms.
While cautious about the efficacy of adult stem cells, the author skips over the implications of the fact that embryonic stem we can turn into “any cell in the body.” It’s that ability that is most dangerous and problematic, since there is the risk of tumors when they turn into an undesirable type or multiple types of cells.
