What are embryonic stem cells?

Famous quotes containing the words embryonic, stem and/or cells:

    Quintilian [educational writer in Rome around A.D. 100] thought that the earliest years of the child’s life were crucial. Education should start earlier than age seven, within the family. It should not be so hard as to give the child an aversion to learning. Rather, these early lessons would take the form of play—that embryonic notion of kindergarten.
    C. John Sommerville (20th century)

    All things seem mention of themselves
    And the names which stem from them branch out to other referents.
    Hugely, spring exists again.
    John Ashbery (b. 1927)

    The twelve Cells for Incorrigibles ... are also carved out of the solid rock hill. On the walls of one of the cells human “liberty” is clearly inscribed, with the “liberty” in significant quotation marks.
    —Administration in the State of Ariz, U.S. public relief program (1935-1943)
