简介：
Overview
This protocol describes an in situ perfusion technique for the mouse lower body, targeting organs such as the bladder, prostate, sex organs, bone, muscle, and foot skin. It enables researchers to study drug delivery and immune interactions within these organs without traditional ex-vivo limitations.
Key Study Components
Area of Science
- Neuroscience
- Biology
- Pharmacology
Background
- Traditional ex-vivo methods have limitations in perfusing certain organs.
- This technique avoids main clearance organs, allowing for targeted studies.
- It is particularly useful for understanding drug delivery mechanisms.
- Immune interactions can be assessed within the perfused organs.
Purpose of Study
- To develop a method for in situ perfusion of the mouse lower body.
- To facilitate research on drug delivery to specific organs.
- To investigate immune responses in the perfused tissues.
Methods Used
- Preparation of a circulating water bath and water-jacketed components at 37 degrees Celsius.
- Use of a bubble trap within a moist chamber as the perfusate reservoir.
- Catheterization of the mouse in a supine position.
- Confirmation of anesthesia through lack of response to pedal reflex.
Main Results
- Successful perfusion of the bladder, prostate, and other lower body organs.
- Enhanced understanding of drug delivery dynamics.
- Insights into immune interactions within the perfused organs.
- Demonstration of the feasibility of this technique for future studies.
Conclusions
- The in situ perfusion technique is effective for studying lower body organs in mice.
- This method opens new avenues for research in drug delivery and immunology.
- Future applications may include various therapeutic and experimental contexts.
What is in situ perfusion?
In situ perfusion is a technique that allows for the delivery of fluids directly into organs while they remain in the living organism.
Why is this method preferred over traditional ex-vivo methods?
This method avoids the limitations of traditional ex-vivo techniques, allowing for more accurate studies of drug delivery and immune interactions.
What organs can be perfused using this protocol?
The protocol allows for the perfusion of the bladder, prostate, sex organs, bone, muscle, and foot skin in mice.
How is anesthesia confirmed before the procedure?
Anesthesia is confirmed by checking for a lack of response to pedal reflex in the mouse.
What temperature should the water bath be set to?
The circulating water bath should be set to 37 degrees Celsius before starting the procedure.
What is the purpose of using a bubble trap?
A bubble trap is used to limit the perfusate volume and ensure a smooth flow during the perfusion process.
