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.
