EurekAlert -- For the first time in the world scientists have succeeded in developing human embryonic stem cells (hESCs) from a single cell, or blastomere, of a 4-cell stage embryo, the 24th annual conference of the European Society of Human Reproduction and Embryology heard today (Wednesday 9 July). Dr. Hilde Van de Velde, from the Vrije Universiteit Brussel (VUB), Brussels, Belgium, said that their research meant that it might be possible in the future to produce hESC lines at an earlier stage without destroying the embryo.
