Tissue Analysis of Liver Grafts as a Predictor of Transplant Outcome.
Tissue Analysis (Histological, Ultrastructural and Molecular) of Liver Grafts as a Predictor of Transplant Outcome.
IRCCS Azienda Ospedaliero-Universitaria di Bologna
200 participants
Jan 17, 2023
INTERVENTIONAL
Conditions
Summary
Despite the good clinical results in terms of outcome with the application of HOPE prior to liver transplantation, very little is still known about the phenotypic and molecular changes that occur during perfusion/preservation during HOPE, particularly with regard to endothelial trophism and activation. Delving into these aspects would be very useful to allow personalised perfusion treatments in the future, thus improving the outcome of transplantation.
Eligibility
Inclusion Criteria6

- Availability of enough tissue for histological, immunohistochemical and RT-PCR analysis.
- HOPE performed on the liver graft prior to transplantation.
- For Recipients:
- Availability of enough tissue for histological, immunohistochemical and RT-PCR analysis.
- Age greater than/equal to 18 years.
Exclusion Criteria1
- None

Interventions
2 µm sections will be cut from the paraffin blocks for histochemical and immunohistochemical (IHC) investigations. IHC will be performed with an automated stainer (Ventana/Roche®, Ventana Medical Systems, USA) for the endothelial markers CD34, ERG, Nestin and Caveolin-1
Custom RT-PCR analyses will be performed manually for the transcripts (mRNA) of the ERG, Nestin, VEGFR and other genes, at the Pathology Anatomy lab hall. 18 (Prof. D'Errico). Total RNA will be extracted from the paraffin blocks with the RecoverAll™ Total Nucleic Acid Isolation kit (Invitrogen). Reverse Transcriptase will be performed with the High Capacity Reverse Transcription kit (Life Technologies), using the specific primers. Real-Time PCR will be performed with the CFX Connect Real-Time PCR Identification System (BioRad).
