Abstract:
:The subject is first identified in terms of the new understanding of a pre-embryonic phase preceding the traditional embryonic and fetal periods of formation and development. Sample fields and purposes of pre-embryonic research are instanced, some with direct therapeutic intent, others with foreseeable but not immediate clinical application. The ethics are discussed, first to answer the question, should it be done at all, and then, how it may be properly done.
