OSTEOGENIC POTENTIAL AND IMMUNOGENICITY OF HUMAN AMNIOTIC MEMBRANE: IN VITRO AND IN VIVO STUDIES

SummaryHuman amniotic membrane has interesting properties for regenerative medicine. To use it as an Advanced Therapeutic Medicinal Product in bone surgery, we are evaluating: the necessity of its osteodifferentiation and the impact on immunogenicity; its optimal condition for storage.IntroductionThe human Amniotic Membrane (hAM) is known to have a good potential to help the regeneration of tissues. It has been used for 100 years in many medical disciplines because of its properties: a flexible scaffold containing stem cells and growth factors, with low immunogenicity and anti-microbial, anti-inflammatory, anti-fibrotic and analgesic properties. Previous published data showed the possibility of in vitro osteodifferentiation of the whole tissue. We aim to use this «boosted membrane» as an Advanced Therapeutic Medicinal Product for bone repair to treat large defects or pseudarthrosis, so, we are studying:The necessity to osteodifferentiate the tissue and its consequence on the immunogenicity; Its in vivo os...
