Floor plate Fibros + Vector (control) Fibros + Netrin-1 Fibros + Netrin-2 What else would you want to do? What can you conclude? a. Only netrin 1 is a specific chemoattractant for these neurons b. Only netrin 2 is a specific chemoattractant for these neurons c. Both netrin 1 and 2 are specific chemoattractants for these neurons d.Both netrin 1 and 2 are chemoattractants, but not necessarily specific
mRNA localization shows • a gradual gradient of Netrin-2 and Shh • a steep gradient of Netrin 1, in and directly adjacent to the floorplate
