I noticed something bizzare, there is a line in the page that reads " It has more recently been shown that cell fate determinants such as wnt and sonic hedgehog(shh) can also act as guidance cues."

I don't think that is correct, can someone who is more experience on this topic than I, please fix it

[edit] Expanding the Article

Hi, I'm going to be editing this page. I plan to just expand all the categories and supply more detailed information in each one. I also plan on adding another category about axon and branch growth in addition to the category on axon guidance. The images that I will be adding are my own, and I am willing to make any changes to the images if anyone has suggestions. I will make these changes soon, and they will probably be made in just one or two additions. Chris1387 (talk) 19:04, 4 April 2008 (UTC)

I think it is true that shh at least can act as a repulsive cue in the optic chiasm. I'm not perfectly sure how this works, but isn't the target of Shh-Signaling (Ci/Gli) bound to microtubili by factors that are phosphorylated during Shh-Signaling? I hope someone knows better than me... Clbl134 —Preceding unsigned comment added by 132.230.21.52 (talk) 16:50, 16 April 2008 (UTC)
