Tosk, a biotech company in San Francisco, is reported to be able to introduce new genetic materials to somatic cells and germ cells in animals by simple injecting genetic materials in the blood stream. Using a combination of transposase and the P-elements from Drosphilia species, the technology is claimed to be able to allow extra DNA to integrate into human and mouse cell culture in high efficiency. It was further indicated that in mice treated with such a technology, as much as 40% of the offsprings carry the transgene.
