化学療法誘発性血管毒性 - リアルタイムインビボイメージング

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
