Photothrombosis Model Development Service

Are you currently facing challenges with long preclinical study timelines or difficulty in establishing consistent and relevant in vivo models for cerebrovascular research? Our photothrombosis models development services help you accelerate drug discovery and obtain highly reproducible, physiologically relevant stroke models through advanced photochemical lesion induction techniques and comprehensive characterization.

Ischemic stroke, a devastating cerebrovascular event, necessitates accurate preclinical modeling to advance therapeutic discovery. Photothrombosis models, employing light-activated dyes to induce focal thrombosis, have emerged as powerful tools. This method enables the creation of highly reproducible and anatomically precise ischemic lesions, mimicking microvascular occlusions seen in human stroke. Their utility in studying neuroprotection, neuroinflammation, and brain plasticity is increasingly recognized in the scientific literature, providing a credible platform for rigorous preclinical investigation.

Workflow:

The development of bespoke photothrombosis models at CBL follows a systematic and transparent workflow, designed for optimal precision and client collaboration, ensuring clear outcomes at each stage.

• Required Starting Materials:

To initiate our service, clients typically provide:

1. Detailed Project Scope: Clear objectives, target brain regions (e.g., specific cortical areas, subcortical structures), desired lesion characteristics (size, severity), and specific research questions (e.g., neuroprotection, inflammation, behavioral recovery).
2. Animal Strain Preferences: Information on preferred rodent strains (e.g., C57BL/6 mice, Wistar rats) and any specific transgenic lines relevant to the study.
3. Proposed Experimental Design: Outline of treatment groups, sample sizes, and duration of study, enabling us to design the most suitable model.

• Final Deliverables:

Upon completion of the service, clients will receive:

1. Detailed Study Report: A comprehensive document outlining the optimized model parameters, experimental protocols, and all raw and analyzed data.
2. Histological Images & Infarct Maps: High-resolution images from stained brain sections with quantified infarct volumes.
3. Behavioral Data Sets: Comprehensive data files from all performed behavioral assessments, including statistical analyses and graphical representations.

• Estimated Timeframe:

The typical timeframe for photothrombosis models development services ranges from 8 to 16 weeks, depending on the complexity of the desired model, the scope of characterization, and the number of animals required. Project duration can be influenced by factors such as the need for extensive preliminary optimization, the inclusion of long-term behavioral follow-up, and integration of advanced imaging modalities.

Customer Reviews:

"The reproducibility using CBL's photothrombosis models in our neuroinflammation research has significantly improved the statistical power of our studies. The consistent lesion size allowed for clear differentiation of treatment effects, far superior to previous mechanical models."

— [Spring 2024], Dr. L***a Smith

"CBL's expertise in optimizing the light parameters for our specific cortical region of interest was invaluable. We achieved incredibly precise and localized ischemic lesions, which greatly facilitated our investigation into neuronal network plasticity. Their attention to detail on experimental setup truly makes a difference."

— [Summer 2023], Prof. M***k Johnson

"Compared to traditional MCAO models, the minimal invasiveness of CBL's photothrombosis service meant significantly reduced animal stress and higher survival rates, which was crucial for our long-term behavioral recovery studies. The high quality of their histological analysis also provided clear evidence of lesion boundaries."

— [Winter 2024], Dr. P***l Davis

Photothrombosis Models

Photothrombosis models represent a sophisticated and increasingly favored approach to inducing focal ischemic injury. Unlike mechanical occlusion methods, this technique leverages a photochemical reaction to create a well-defined thrombotic lesion.

The process involves the systemic administration of a photosensitive dye (such as Rose Bengal or Erythrosin B). When a specific region of interest in the brain is then illuminated with a precisely calibrated light source (e.g., a laser at a particular wavelength), the dye undergoes photoactivation. This activation generates singlet oxygen, a highly reactive molecule that induces oxidative damage to the endothelial cell membranes lining the microvessels. This damage triggers a rapid and localized cascade of platelet aggregation and thrombus formation, culminating in a highly controlled interruption of local cerebral blood flow.

This unique mechanism of action allows for the induction of focal ischemia within superficial cortical or even deeper brain structures, mimicking the microvascular pathologies often observed in human ischemic stroke.
