Several years ago I tried to establish a simple invertbrate model 
for the study of regeneration by describing the cellular reaction to 
woundng in the leech, Piscicola salmositica.  Unlike rather closely 
related polychaetes that regenerate readily, these leeches do not; 
they merely seal and repair the wound with "scar" tissue.  I always 
felt that the contrast between such closely related groups might be 
useful in clarifying regeneration control mechanisms, but could 
never find financial support to carry on.  If anyone is interested 
in the series of small papers, they may be found in the Journal for 
Invertebrate Pathology, early 1970s.
