Open the CIPO recordAbstract From the Canadian patent
A sub-population of HES cells is identified which is positive for specific HES markers. These cell types are identified by expression of particular GCTM-2 antigens. A method based on the identification of GCTM-2 can differentiate between substantially undifferentiated or differentiated cell populations. Spontaneous differentiation often occurs in HES cultures resulting in nonhomogeneous cell cultures. The invention also provides further sub populations of cells within differentiated cultures of HES cells that are SCL or epithelial in nature.

Why it's free to use
- Filed November 11, 2002. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended November 11, 2022.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by November 11, 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.
