CAP–cAMP increases the rate of formation of the closed promoter complex, CAP–cAMP provides CPC for conversion to the open promoter complex. 

Thus, the net effect of CAP–cAMP is to increase the rate of open promoter complex formation.

Second possible mechanisms for neoblast specification during regeneration:

Multipotent progenitor cells are positioned throughout the planarian with their lineages specified based on their position. These divide and produce postmitotic blastema cells that differentiate into their specified fates.
