Open the CIPO recordAbstract From the Canadian patent
It is shown here that hedgehog proteins or mimicking agents possess novel activities beyond phenotype specification. Using cultures derived from the embryonic day 14.5 (E14.5) rat ventral mesencephalon we show that hedgehog or , mimicking agents are also trophic for dopaminergic neurons. Interestingly hedgehog or mimicking agents not only promote dopaminergic neuron survival but also promote the survival of midbrain GABA-immunoreactive (GABA-ir) neurons.

Why it's free to use
- Filed July 24, 1998. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended July 24, 2018.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 24, 2020.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
