blastema

an undifferentiated mass of animal cells that later forms a structure or organ either embryologically or through regeneration, e.g. the head of a flatworm.

blastema

1. the primitive substance from which cells are formed.
2. a group of cells that will give rise to a new individual, in asexual reproduction, or to an organ or part, in either normal development or in regeneration.
