At the present time, the funding into research on thalidomide embryopathy and the way the drug acts on the embryo is pretty much at zero. There's very little interest in doing that research, because the drug is no longer, in our countries anyway, used in situations that might cause those problems.
Where the funding goes is based on drug safety and how you can make the drug safer. That's the research area in which we're going to find out how this drug acted and understand a bit more about diagnostic tools that we could probably use from it.
That's what I'm doing right now. It's what a few other labs around the world are doing. The best animal model would be primates, monkeys, but there are ethical reasons we can't use those, which is why we use chickens, fish, and mice, and ultimately clinical trials.
It's going to take some time to understand the exact mechanisms, because the funding is just not there at the moment.
