Abstract

"SISTEMA DE TECIDO COM CéLULAS TRONCO NãO DIFERENCIADAS DERIVADAS DO LIMBUS DA CóRNEA". A presente descrição apresenta um sistema de tecido com células tronco límbicas auto-regenerativas, em que as célula tronco límbicas são principalmente células tronco não diferenciadas (USCS). O sistema de tecido é derivado do tecido límbico da córnea isolado, e é apropriado para restaurar deteriorações da superfície ocular, particularmente aquelas que resultam das deficiências das células tronco límbicas. O sistema de tecido é gerado ao aumentar seletivamente o sistema de tecido para as USCS, por exemplo, mediante a seleção e a classificação das células que expressam marcadores de superfície específicos de células tronco, tal como o marcador 4 de antígeno embriónico específico de estágio (SSEA-4) . Depois do isolamento, as USCs são cultivadas em uma base de tecido na presença de um meio enriquecido para gerar o sistema de tecido, o qual é apropriado para o transplante, o implante, ou o enxerto.
