化疗引起的血管毒性 - 实时在体内船舶减值成像

Overview

This article describes the method of fibered confocal fluorescent microscopy (FCFM) for imaging physiological phenomena at cellular and sub-cellular levels in animal subjects. The technique allows for real-time visualization of vasculature and its responses to various stimuli.

Key Study Components

Area of Science

• Neuroscience
• Cell Biology
• Imaging Techniques

Background

• Fibered confocal microscopy provides high-definition imaging capabilities.
• It is particularly useful for studying vascular responses in live animal models.
• Challenges exist in setting up the system and capturing stable images.
• Fitzy dextrin is used to enhance visualization of blood vessels.

Purpose of Study

• To visualize the vasculature and its response to stimuli in real-time.
• To evaluate potential vascular toxicity of agents like chemotherapeutics.
• To demonstrate the FCFM technique for researchers new to the method.

Methods Used

• Calibration of the fibered confocal microscope.
• Intravenous injection of fitzy dextrin into the animal.
• Real-time imaging of blood vessels during and after treatment.
• Demonstration of the procedure by a trained postdoc.

Main Results

• Successful visualization of vasculature in live subjects.
• Real-time imaging allows for assessment of vascular responses.
• Potential applications in evaluating vascular toxicity of drugs.
• Identification of challenges faced by new users of the technique.

Conclusions
