Animal Stem Cells and Regeneration · Zoology

The regenerative process in Planarians (flatworms) is primarily driven by a population of pluripotent adult stem cells known as:

  1. Neoblasts (pluripotent stem cells)
  2. Blastema progenitor cells
  3. Satellite muscle stem cells
  4. Mesenchymal stromal stem cells
Show answer and explanation

Correct answer: Neoblasts (pluripotent stem cells)

Neoblasts are the only dividing cells in Planarians and are capable of differentiating into any cell type required to rebuild missing body parts. This makes them a classic model for studying extreme regeneration.
