Stem cell systems and regeneration in planaria - PMC
The de novo regeneration of the planarian eye via the coalescence of individually migrating progenitors arising far from their target site provides a striking example of self-organization (Lapan and Reddien 2011). Assembling a structure as complex as the eye necessitates both multiple cell fate choices and precise spatial arrangements of cells.
