Open the CIPO recordAbstract From the Canadian patent
The present invention relates to purified smooth muscle progenitor cells and a method for isolating such cells. The purified smooth muscle progenitor cells of the present invention are capable of being induced into the smooth muscle cell lineage at high efficacy (i.e. greater than 60% conversion). The method comprises the steps of transforming cell populations that contain totipotent or pluripotent cells with DNA constructs that are expressed only in the smooth muscle cell lineage, inducing a portion of those cells and identifying those cells that express the construct only after the cells are induced.

Why it's free to use
- Filed March 19, 2002. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended March 19, 2022.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 19, 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.
