Researchers create genetically matched embryonic stem cells for transplantation
...'s laboratory at Children's Hospital Boston is now trying to replicate its results with human eggs. As Daley noted, there are several potential limitations to embryonic stem cells generated by parthenogenesis. First, since parthenogenetic embryonic stem cells are made from eggs, the technique is only appli...U of Illinois professor tout health benefits of Hispanic foods and beverages
