Area of Science:

Hepatology
Surgical techniques
Animal models

Background:

Partial hepatectomy (PH) is a long-established surgical technique in rodents.
PH remains crucial for analyzing liver regeneration and hepatocarcinogenesis signaling pathways.
The utility of PH has grown with the availability of genetically modified mouse models.

Purpose of the Study:

To provide a comprehensive standard operating procedure (SOP) for partial hepatectomy (PH) in mice.
To offer guidelines for planning and executing PH experiments, incorporating over a decade of experience.
To ensure the SOP aligns with current animal welfare regulations, including recent EU changes.

Main Methods:

Development of a detailed step-by-step surgical protocol for PH in mice.
Inclusion of recommendations for animal selection (age, gender), anesthesia, and experimental design.
Emphasis on critical surgical steps and postoperative management.

Main Results:

A standardized, easy-to-follow SOP for mouse partial hepatectomy.
Established recommendations for optimizing PH experiments.
Guidance on legal and ethical considerations for PH studies.

Conclusions:

This SOP facilitates the legal, ethical, and effective implementation of partial hepatectomy in mouse models.
It serves as a valuable resource for liver researchers utilizing PH for regeneration and carcinogenesis studies.
The protocol adheres to international standards and updated animal welfare guidelines.
