Recently, a new lyopreservation method has been developed for preservation of amnion that also retains the endogenous viable cells. The objective of this study was to use this method for lyopreservation of TR-free chorionic membrane (viable lyopreserved chorionic membrane [VLCM]) and compare it with the viable cryopreserved chorionic membrane (VCCM). A second objective was to investigate the immunogenicity of chorion, an important question that has not been fully addressed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Approach:<\/jats:title>\n                    <jats:p>\n                      Chorion immunogenicity was tested\n                      <jats:italic toggle=\"yes\">in vitro<\/jats:italic>\n                      in a mixed lymphocyte reaction and lipopolysaccharide (LPS) challenge assay, and\n                      <jats:italic toggle=\"yes\">in vivo<\/jats:italic>\n                      in a mouse subcutaneous pocket implantation model.
