In response, the Harvard Stem Cell Institute, inaugurated last March, has generated 17 new embryonic stem-cell lines without a single federal dollar and has offered the lines free to scientists worldwide. This effort is already yielding astonishing results. Scientists at Advanced Cell Technology in Worcester, Massachusetts, reported in November that they had for the first time ever coaxed human embryonic stem cells, many from the
Harvard lines, into billions
of human retinal cells.
