Definition of the problem: Stem cell transplantations from umbilical cord blood, especially if from autologous origin, are often treated with distrust. Not only are the therapeutic effects controversial, but the question of ownership is also hard to answer from an ethical point of view. Furthermore, the extraction of umbilical cord blood is already related to information about the factual and potential health condition of the child and its parents. Arguments and conclusion: The three problems will be discussed separately. Despite certain (...) uncertainties, there are no weighty ethical arguments against the extraction of umbilical cord blood for autologous purposes. The owner of the umbilical cord blood should be the mother. The question of information is not at all typical for this problem area and does not carry more weight here than in other relevant medical situations. (shrink)
