Embryo Organisms in the early stages of growth and development.
In animals, embryos are characterized by the cleavage of the fertilized
eggs to many cells, the laying down of the three germ layers, and formative
steps in organ

one concluded that an embryo was not a person yet, the embryo could still as a
human embryo warrant more respect and care than mere tissue. The embryo is
potentially associated with a human person in the future. Would proper care for

ethical status of human embryonic stem cells partly hinges on the
question of whether they should be characterized as embryos or specialized
bodily tissue. Although the answer to this question will be less important to
those who believe that
