Detailed Description

Human liver slice culture hLSCs will be used from non-tumor liver tissue collected by biopsy from patients undergoing abdominal surgery, who have signed informed consent and agree to perform a liver biopsy for the specific research protocol.

The study is "low level interventional" when a small portion (approximately 10 mm in diameter) of liver tissue macroscopically free from parenchymal alterations obtained in the open at the site of surgery for primary or secondary liver tumors will be taken (hepatic metastases from colorectal, pancreatic or breast cancer). The goal is to create organotypic liver cultures (hLSC) derived from liver biopsies taken from patients undergoing abdominal surgery.

for primary or secondary liver tumors for the molecular characterization of liver fibrosis.

Use hLSC to study the liver microenvironment and molecular determinants involved in fibrosis through single cell sequencing; compare the sequencing data obtained with hLSC with that obtained via characterization of a GEMM whose generation is foreseen in the same project financed by the MoS.

To generate this GEMM, the pro-fibrotic Hipk2 gene was specifically deleted in the tissue liver (HIPK2-liver knock-out, HIPK2-LKO) and liver fibrosis will be induced through a high-fat, low-choline diet.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Other: Biopsy sample in an area of liver macroscopically free from parenchymal alterations
Patients undergoing abdominal surgery for primary or secondary liver tumors (liver metastases from colorectal, pancreatic, or breast), from which we proceed to the preparation of organotypic cultures of liver (hLSC) derived from liver biopsies taken from patients undergoing abdominal surgery for primary or secondary liver tumors for the molecular characterization of liver fibrosis.
Diagnostic test: Biopsy from patients undergoing surgery abdominal.
A small portion (about 10 mm in diameter) of liver tissue was collected macroscopically free from alterations of the parenchyma obtained in the open at the site surgery for primary or secondary liver tumors, for the preparation of cultures of organotypic liver slices.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Molecular characterization of liver fibrosis
Time Frame: 24 months
Creation of organotypic cultures of liverderived from liver biopsies taken from patients undergoing abdominal surgery for primary or secondary liver tumors for the molecular characterization of liver fibrosis.Patients will undergo abdominal surgery (as per clinical practice), during which a biopsy will be performed in an area of the liver macroscopically free from parenchymal alterations, approximately 20/25 slices will be obtained from each sample. The hLSCs will come used to study the hepatic microenvironment in the presence or absence of pro-fibrinogenetic stimuli e of anti-fibrotics by time-lapse analysis and confocal immunofluorescence microscopy multiple and through single cell sequencing.
24 months

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Study of the hepatic microenvironment
Time Frame: 24 months
Use hLSCs to study the liver microenvironment and the molecular determinants involved in it fibrosis through single cell sequencing (single-cell RNA sequencing);
24 months
Compare the sequencing data
Time Frame: 24 months

Compare the sequencing data obtained with hLSCs with those obtained through the characterization of a GEMM. A biopsy will be performed after abdominal surgery (as per clinical practice), in an area of the liver macroscopically free from parenchymal alterations.

hLSCs will be analyzed over the following week for viability and fibrosis induction using fibrosis-specific stains for time-lapse dynamic imaging (IncuCyte), i.e. picrosirius red, Masson's trichrome, and quantitative RT-PCR and multiplex immunofluorescence
