title: Anthropological and ethical reflections on the production and use of embryonic stem cells.
abstract: Stem cells and their potential therapeutic application have generated tremendous public interest, great enthusiasm among researchers and intense commercial interest. There are diverse sources of stem cells. According to their origin and their biological characteristics, they are classified as embryonic stem cells, germline stem cells and tissue stem cells. Until now, the most concrete therapeutic results have come from some adult tissue stem cells, with promising prospects also being offered by umbilical cord stem cells. Regarding embryonic stem cells, there is concern that they would be difficult to control in vivo. Nonetheless, many researchers are still pursuing their potential uses, convinced that they will be useful not only for study, but also for therapy, especially as a result of their high capacity for self-renewal as well as their broad potential for differentiation. This discussion which is eminently scientific in nature, and not lacking in ethical and political repercussions, will not be entered into above all regarding the allocation of available intellectual and economic resources.
