spatial feedback inhibition controls neoblast differentiation to
regulate reversible growth of the planarian brain by Eric M Hill
and Christian P Petersen
What is the central hypothesis? (in your own words!) Using Figure 8 as a guide, describe the role Wnt plays in planarian brain regeneration. How might the results of this research suggest any future medical or health applications, or further experiments aimed at understanding human health? What were some strengths and weaknesses of this research?
