Hepatectomy parcial é uma técnica estabelecida para investigar regeneração hepática e hepatectomy excessiva é relatado para imitar o modelo de AHF. Entre modelos animais de AHF, roedores, sobretudo ratos, são o modelo mais pesquisado. Para obter um modelo de lesão hepática em ratos, até um 70% hepatectomy tem sido relatado com uma taxa de sobrevivência bom25,26. No entanto em nude e outro rato imunodeficientes, um hepatectomy 70% foi relatado como fata...

Atualmente, transplante de hepatócitos é proposto como uma alternativa ao transplante de órgão inteiro para tratar pacientes com distúrbios hepáticos graves. Acredita-se que ele pode ponte pacientes de transplante de órgão inteiro1. Além dos hepatócitos alogênico2, hepatócitos xenogénica3 e hepatócitos derivados de células-tronco4 também estão sendo investigados em modelos animais. Neste contexto, a orientação e enxertia potencial das células transplantadas no receptor é um critério importante para a terapia de célula com base na insuficiência hepática aguda (AHF).
Para investigar o transplante de hepatócitos ou células hepatócito5, AHF é criada em um modelo animal por cirúrgica6 ou procedimentos farmacológicos7 , seguidos de transplante de células. Tornar-se um modelo animal de AHF por reagentes farmacológicos, hepatotoxinas muitos como d-galactosamina8, paracetamol9, tetracloreto de carbono10, tioacetamida11, Concanavalina A12, lipopolissacarídeo13 , etc., têm sido utilizados. Desta lista, cada reagente gera um conjunto único de características para AHF, mas infelizmente não reagente único imita as AHF humana. Além disso, a AHF induzida por hepatotoxinas leva um longo tempo, o que coloca os animais sob estresse crônico, e obter resultados reprodutíveis são difíceis de obter.
Por outro lado, o procedimento cirúrgico de hepatectomy parcial (PHx) é dependente de habilidade, e obter resultados reprodutíveis são fáceis de obter depois de desenvolver as habilidades necessárias. Para induzir AHF por intervenção cirúrgica sozinha, ressecção de mais de 70% do fígado é necessária; no entanto, menos do que um hepatectomy 70% ainda pode ser utilizado para estudar a enxertia e proliferação de transplantadas células no fígado para analisar sua capacidade terapêutica durante dano hepático14. O transplante de hepatócitos foram realizados post hepatectomy através do peritônio15, cauda veia16, veia hepática17ou o baço18. Atualmente, infusão de veia hepática e transplante intrasplenic dos hepatócitos são os procedimentos preferenciais, porque são mais fáceis de reproduzir.
Neste trabalho, descrevemos um procedimento para uma hepatectomy parcial de 30% na NOD. SCID (ASSENTIMENTO. CB17-Prkdcscid/J) ratos em que o lobo esquerdo do fígado é extirpado. Ele é seguido por transplante de hepatócitos de rato (C57BL/6-Tg (UBC-GFP) 30Scha/J) expressando GFP 0,2 milhões, bem como origem humana NeoHep19 no baço. Este procedimento leva a enxertia das células transplantadas no fígado. Este procedimento é menos invasivo e uma técnica minimamente dolorosa.

intrasplenic transplantation of hepatocytes after partial hepatectomy in nod.scid mice

Hepatectomy parcial é um método versátil e pode ser reproduzido para estudar a regeneração hepática e o efeito da terapêutica de célula com base em várias condições patológicas. Hepatectomy parcial também facilita a enxertia aumentada e proliferação das células transplantadas por neovascularização acelerada e migração de células para o fígado. Aqui, descrevemos um protocolo simples para executar hepatectomy 30% e o transplante de células no baço de um não-obesos diabéticos/grave combinado NOD imunodeficientes. SCID (ASSENTIMENTO. CB17-Prkdcscid/J) rato.
Neste procedimento, são feitas duas pequenas incisões. A primeira incisão é expor e fazer a ressecção do lobo esquerdo do fígado, e outra pequena incisão para expor o baço para o transplante intrasplenic de células. Este procedimento não requer nenhuma habilidade cirúrgica especializada, e pode ser completado em 5-7 minutos com menos estresse e dor, recuperação mais rápida e melhor sobrevivência. Nós demonstramos que o transplante de hepatócitos isolados de uma proteína verde fluorescente (GFP), expressando o rato (transgénico C57BL/6-Tg (UBC-GFP) 30Scha/J), bem como hepatócito como células de origem humana (NeoHep) em parcialmente hepatectomized NOD. Ratos SCID.

Proliferação hepatocyte após hepatectomy parcial de 30%: A proliferação dos hepatócitos nos restantes fígada após 30% hepatectomy foi examinada por imuno-histoquímica (IHC) mancha para um marcador de proliferação celular, Ki-67. Post um dia hepatectomy, os ratos foram sacrificados, os lóbulos de fígado restantes foram extirpados e cortes de parafina foram obtidos. As seções foram coradas com anticorpo Ki-67, seguido de rotulagem com anticorpo secundário conjugado de horseradish peroxidase...
