简介：
Overview
This article presents a semi-invasive optical microscopy technique for inducing a Rose Bengal photothrombotic clot in the somatosensory cortex of a mouse in vivo. The procedure details the induction of the clot, imaging techniques, and immediate analysis of cellular responses.
Key Study Components
Area of Science
- Neuroscience
- Optical Microscopy
- Photothrombosis
Background
- Photothrombotic clots are used to study ischemic strokes.
- Rose Bengal is a dye that facilitates clot formation under laser illumination.
- In vivo imaging allows for real-time observation of cellular responses.
- Creating a thin cranial window is critical for successful imaging.
Purpose of Study
- To demonstrate a method for inducing and analyzing photothrombotic clots.
- To provide a detailed protocol for researchers new to this technique.

Methods Used
- Anesthetizing the mouse and preparing a cranial window.
- Injecting Rose Bengal and using a laser to induce thrombosis.
- Monitoring physiological parameters throughout the procedure.
- Analyzing the effects of the clot using imaging techniques.
Main Results
- Successful induction of clots was achieved in the somatosensory cortex.
- Immediate cellular responses were observed post-induction.
- Longitudinal imaging provided insights into stroke progression.
- Clot formation was confirmed through TTC staining for cerebral infarction.
Conclusions
