A Bruno-like gene is required for stem cell maintenance in planarians.

The regenerative abilities of freshwater planarians are based on neoblasts, stem cells maintained throughout the animal's life. We show that a member of the Bruno-like family of RNA binding proteins is critical for regulating neoblasts in the planarian Schmidtea mediterranea. Smed-bruno-like (bruli) mRNA and protein are expressed in neoblasts and the… CONTINUE READING
