简介：
Overview
This article presents a method for stable transfection of murine hepatocytes in vivo using hydrodynamic tail vein injection of transposon-based integration vectors. The technique allows for long-term expression of transgenes or miR-shRNA, which can be induced by doxycycline.

What is hydrodynamic tail vein injection?
It is a technique used to deliver DNA into liver cells by rapidly injecting a large volume of solution into the tail vein.
What are the advantages of this transfection method?
It allows for stable transfection and long-term expression of genes in hepatocytes, facilitating various research applications.
How does the inducible expression work?
Inducible expression systems can be activated by specific compounds, such as doxycycline, allowing for controlled gene expression.
What applications can this method be used for?
It can be applied to study liver cancer mechanisms, regeneration, and other liver-related research areas.
Who demonstrated the procedure in the study?
The procedure was demonstrated by Eric Hubner, a medical student from the laboratory.
What is the significance of using shRNA?
Short hairpin RNA (shRNA) is used to silence specific genes, allowing researchers to study gene function and regulation.
