By exploiting an HIV protein that readily traverses cell membranes, Carnegie Mellon University scientists have developed a new way to introduce a gene-like molecule called a peptide nucleic acid (PNA) directly into live mammalian cells, including human embryonic stem (ES) cells. The work, published online December 2 in Chemical Communications, holds considerable promise in genetic engineering, diagnostics and therapeutics.
