7

What secretes Fgf10? What does it do?

Lateral plate mesoderm, thickens ectoderm- apical ectodermal ridge which secretes Fgf4 and 8 - progress zone, proximodistal growth

8

What controls dorsoventral development of limbs?

Wnt7 (dorsal) and Engrailed-1 (ventral, inhibits wnt7)
Secreted by ectoderm

9

What controls craniocaudal development of limb?

Shh secreted by caudal zone of polarising activity, diffuses in cranial direction
