Removal of the apical ridge leads to

#5. Developmental Biology
  1. regeneration of the entire limb bud from underlying mesoderm
  2. formation of structures proximal to the apical ridge, but no formation of new distal structures
  3. regeneration of a new apical ridge from adjacent epidermal tissue
  4. continued development in the progress zone, once the apical ridge has induced progress zone formation
