[Action of broken fractions of regeneration blastema on the synthetic activity of posterior fragments or Dendrocelum lacteum cut behind the pharynx].

Pounded blastemas of regeneration favour RNA synthesis is neoblasts of posterior parts of Dendrocoelum lacteum, cut behind the pharynx, which normally fail to regenerate a head; and induce excrescences. Fixed parenchyma cells and other differentiated tissues do not synthesize RNA with pounded blastemas.
