Preparation and characterization of resorbable hydrogels membranes used bone tissue engineering. In: INTERNATIONAL SYMPOSIUM ON MACROMOLECULES, 41st, July 16-21, 2006, Rio de Janeiro, RJ. <b>Proceedings...</b> Disponível em: http://repositorio.ipen.br/handle/123456789/15661.http://repositorio.ipen.br/handle/123456789/15661New composites membranes of poly(acid lactic)/poly(ethylene glycol)/hydroxyapatite (PLLA/PEG/HA), drawn with characteristics appropriate for guided bone regeneration (GBR), were prepared by casting from chloroform solutions. The combination of the components, PLLA (resorbable polymer), PEG (polymer with affinity to the biological fluids) and HA (ceramic with good mechanical and biological properties), confers to the membranes new mechanical and biological characteristics, ideal for mimicking the bone matrix and encouraging the cell growth. The obtained PLLA/PEG/HA membranes showed a porous morphology, similar to the bone matrix, suitable for cells penetration, anchorage, differentiation and proliferation. Adherence of cultured fibroblasts on PLLA/PEG/HA membranes indicated biocompatibility.openAccessbone tissuesmembranescollagenpolytetrafluoroethylenepolystyreneskeletonbiological regenerationbiodegradationcompatibilityceramicsbiological materialsTexto completo de evento
