Conclusion the unique properties of dendrimers resulting from their unusual structure gave a broad application prospect in the drug delivery system, genetic carriers and other fields.

Using viruses as carriers, they have introduced novel genetic material into embryonic prairie-vole cells, and then grown each modified cell into a complete animal.

Though Fu isn't sure how many people carry such a genetic mutation, she said it's probably rare as the researchers found no other carriers in a sample of 250.
