Open the CIPO recordAbstract From the Canadian patent
Somatic cells are treated with a component contained in ES cells and the activity is detected. Thus, a reprogramming factor can be screened. Moreover somatic cells can be reprogrammed by treating with a component containing the reprogramming factor or the reprogramming factor per se. Since the tetraploid cells as described above are capable of undergoing proliferation and multidifferentiation, cells, tissues and organs usable in transplantation are produced by differentiating the cells.

Why it's free to use
- Filed August 30, 2002. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended August 30, 2022.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by August 30, 2024.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
