23Today I was listening to Science Friday on NPR and they were having a discussion about embryonics and restoring neural pathways to cure paralysis. Suddenly the guest was talking about proteins and growth agents needed and one was called “Sonic Hedgehog”
Sonic Hedgehog??? what is that?I was utterly convinced that I either misheard or the guest was pulling one over the unsuspecting audience. But apparently not. There seems to be a class of genes called “hedgehog” genes found in fruit fly embryoes, which are covered in pointy bumps. In mammals there are three equivalents the desert hedgehog, the indian hedgehog and the sonic hedgehog.
Who knew geneticists were so silly?
BTW there’s also the tiggywingkle hedgehog in zebrafish.
