[On therapeutic use of stem cells and the sources of morality].

The Article deals with the ethical issues around the therapeutic utilization of stem cells (SC), particularly facing with factors of morality: i.e., object of the human action, aims and circumstances. Crucial ethical questions are recognized in the last factor (circumstances), particularly: the origin and the availability of SC, the consequences of the therapeutic action through SC, the diffusion/communication of scientific data around the clinical use of SC. The paper assumes the perspective of the ethics considered as practical-normative science, centered on the human person (as a whole) as the value of reference.
