Human Embryonic Stem Cell Lines Created That Avoid Immune Rejection

ScienceDaily (2007-12-21) -- In a groundbreaking experiment scientists have derived four unique embryonic stem cell lines that open the door for the creation of therapeutic cells that will not provoke an immune reaction in large segments of the population. The stem cell lines are "HLA-homozygous," meaning that they have a simple genetic profile in the critical areas of the DNA that code for immune rejection. The stem cells under development are derived from unfertilized donor eggs, not from fertilized embryos, so the technique does not carry the same ethical burden.
