Diagrams depicting the five stages of oral siphon pigment organ regeneration (see text for details) along the oral siphon (thick black horizontal line) in young (A) and old (B) animals. B. The number and patterning of oral siphon pigment organs is affected by overproduction of pigment cells in old animals. ORB: oral siphon regeneration bands. LMB: longitundinal muscle bands. Open circle: undifferentiated cells. Red circles: red pigment cells, yellow circles: yellow pigment cells. Blue horizontal lines: longitundinal muscle fibers. From Jeffery (2012).
