When the blastema forms after amputation of a newt limb, what processes must the cells undergo in order for regeneration to occur?

#Unit 5. Developmental Biology
  1. The cells must only begin to divide for regeneration to occur.
  2. The cells must simply dedifferentiate in order for regeneration to occur.
  3. Some cells in the blastema will transdifferentiate after amputation, and this allows regeneration to proceed.
  4. Dedifferentiation, cell division, transdifferentiation, and formation of an AER-like function are all involved.
