Hepatectomy parziale è una tecnica consolidata per inquirenti rigenerazione del fegato e hepatectomy eccessivo è segnalato per imitare il modello AHF. Tra modelli animali di AHF, roditori, soprattutto topi, sono il modello più ricercato. Per ottenere un modello di disturbo al fegato in topi, fino a un hepatectomy di 70% è stato segnalato con una buona sopravvivenza tasso25,26. Tuttavia in altri mouse immunodeficiente e nudo, un hepatectomy di 70% è stato seg...

Attualmente, il trapianto dell'epatocita è proposto come alternativa al trapianto d'organo intero per trattare i pazienti con gravi disturbi del fegato. Si ritiene che esso possa colmare pazienti per trapianto di organo intero1. Oltre il trapianto allogenico epatociti2, epatociti xenogenica3 ed epatociti derivati da cellule staminali4 sono anche indagati in modelli animali. In questo contesto, l'homing e attecchimento potenziale delle cellule trapiantate nel destinatario è un criterio importante per la terapia cellulare basata nell'insufficienza epatica acuta (AHF).
Per indagare il trapianto di epatociti o dell'epatocita-come le cellule5, AHF viene creato in un modello animale da chirurgica6 o farmacologici7 procedure, seguite da trapianto di cellule. Per rendere un modello animale di AHF di reagenti farmacologici, molti epatotossine come d-galattosamina8, acetaminofene9, tetracloruro di carbonio10, thioacetamide11, concanavalina A12, Lipopolisaccaride13 , ecc., sono stati utilizzati. Da questa lista, ogni reagente genera un insieme unico di funzionalità per AHF, ma purtroppo nessun singolo reagente imita gli AHF umano. Inoltre, gli AHF indotto da epatotossine richiede molto tempo, che mette gli animali in condizioni di stress cronico, e risultati riproducibili sono difficili da ottenere.
D'altra parte, l'intervento chirurgico di epatectomia parziale (PHx) è dipendente di abilità e risultati riproducibili sono facili da ottenere dopo lo sviluppo di competenze richieste. Per indurre AHF tramite intervento chirurgico da solo, la resezione di più del 70% del fegato è richiesta; Tuttavia, meno di un'epatectomia 70% ancora possa essere utilizzata per studiare l'attecchimento e la proliferazione di trapiantate cellule nel fegato per analizzare le loro capacità terapeutiche durante i danni al fegato14. Il trapianto di epatociti sono stati eseguiti post epatectomia attraverso il peritoneo15, coda vena16, vena epatica17o la milza18. Attualmente, infusione della vena epatica e intrasplenic trapianto di epatociti sono le procedure di comodo, come sono più facili da riprodurre.
In questo articolo, abbiamo descritto una procedura per una 30% di epatectomia parziale in NOD. SCID (CENNO DEL CAPO. CB17-Prkdcscid/J) topi in cui viene asportato il lobo sinistro del fegato. È seguito da trapianto di epatociti di mouse (C57BL/6-Tg (UBC-GFP) 30Scha/J) che esprimono GFP 0,2 milioni nonché di origine umana NeoHep19 nella milza. Questa procedura conduce all'attecchimento delle cellule trapiantate nel fegato. Questa procedura è meno invasiva e una tecnica minimamente dolorosa.

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

Hepatectomy parziale è un metodo versatile e riproducibile per studiare la rigenerazione del fegato e l'effetto di terapeutica delle cellule basata in varie circostanze patologiche. Epatectomia parziale facilita anche la maggiore attecchimento e la proliferazione delle cellule trapiantate da neovascolarizzazione accelerante e migrazione delle cellule verso il fegato. Qui, descriviamo un semplice protocollo per eseguire 30% hepatectomy e trapianto di cellule nella milza di un diabetico non obeso/grave combinata NOD immunodeficienti. SCID (CENNO DEL CAPO. CB17-Prkdcscid/j) mouse.
In questa procedura, due piccole incisioni sono fatte. La prima incisione è quello di esporre e resecare il lobo sinistro del fegato, e un'altra piccola incisione è fatta per esporre la milza per il trapianto di cellule intrasplenic. Questa procedura non richiede alcuna abilità chirurgiche specializzate, e può essere completato in 5-7 minuti con meno stress e dolore, recupero più veloce e migliore sopravvivenza. Abbiamo dimostrato il trapianto di epatociti isolati da una proteina fluorescente verde (GFP) esprimendo mouse (transgenici C57BL/6-Tg (UBC-GFP) 30Scha/J), come pure dell'epatocita come cellule di origine umana (NeoHep) in parzialmente epatectomizzati NOD. Topi SCID.

Proliferazione degli epatociti dopo hepatectomy parziale del 30%: La proliferazione degli epatociti nei rimanenti del fegato dopo epatectomia 30% è stata esaminata secondo immunoistochimica (IHC) per un indicatore di proliferazione delle cellule, Ki-67. Un giorno post epatectomia, i topi sono stati sacrificati, i lobi del fegato restanti sono stati asportati e sezioni della paraffina sono state ottenute. Le sezioni sono state macchiate con anticorpo Ki-67, seguita da etichettatura con anticorpo secondar...

Abbiamo descritto un protocollo per l'esecuzione di epatectomia parziale (PHx) e trapianto di cellule via della milza nel cenno del capo. SCID (CENNO DEL CAPO. CB17-Prkdcscid/j) topi. In questo protocollo, un'incisione è fatta per esporre e resecare il lobo sinistro del fegato seguito da un'altra incisione per il trapianto di cellule intrasplenic.
