Using zebra mussels (\n                      <jats:italic>Dreissena polymorpha<\/jats:italic>\n                      ), we recently demonstrated that induction of biomineralization after exposure to focused extracorporeal shock waves (fESWs) is not restricted to the region of direct energy transfer into calcified tissue. This study tested the hypothesis that radial extracorporeal shock waves (rESWs) also induce biomineralization in regions not directly exposed to the shock wave energy in zebra mussels.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Zebra mussels were exposed on the left valve to 1000 rESWs at different air pressure (between 0 and 4\u00a0bar), followed by incubation in calcein solution for 24\u00a0h.
