Open the CIPO recordAbstract From the Canadian patent
A gene encoding a polypeptide having an activity to support proliferation or survival of hematopoietic stem cells or hematopoietic progenitor cells is isolated by comparing expressed genes between cells which support proliferation or survival of hematopoietic stem cells or hematopoietic progenitor cells and cells which do not support the proliferation or survival. Proliferation or survival of hematopoietic stem cells or hematopoietic progenitor cells is supported by using stromal cells in which the isolated gene is expressed or a gene product of the isolated gene.

Why it's free to use
- Filed April 25, 2003. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended April 25, 2023.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 25, 2025.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
