In Vitro Modeling of Stroke

In vitro models offer tremendous opportunities to model stroke and improve drug discovery pipelines by allowing specific underlying biochemical and molecular mechanisms to be studied under ischemia-like conditions of energy deficiency. At Ace Therapeutics, we are committed to developing customized in vitro models of stroke to enhance the translational capabilities of your drug discovery and development programs.

The Importance of In Vitro Stroke Models

Due to the availability of transgenic strains, rodents are often chosen to construct in vivo stroke models. However, due to the 80 million years of evolution separating rodents and humans, there are species-specific anatomical, cellular, and molecular differences between humans and rodents that may affect the outcome of neuroprotective strategies. In vitro stroke models are used to study specific molecular pathways that occur in stroke pathology. These models have many advantages, they are reproducible, easy to produce and maintain, and cost-effective. In addition, in vitro systems, especially human in vitro systems, can provide very valuable information about drug safety, while also allowing for cost-effective high-throughput screening assays.

Custom In Vitro Models of Stroke

Ace Therapeutics offers comprehensive in vitro stroke modeling services to meet our customer needs. Our laboratory has a full of in vitro facility equipped with cell culture, microscopy, cell isolation systems, flow cytometry analysis, and a variety of assays to assess drug response.

In Vitro Modeling of Ischemic Stroke

Based on innovative cellular technologies and genetic and molecular manipulation platforms, Ace Therapeutics provides customizable, simplified, and highly controlled ischemic stroke in vitro model platforms. We can help you study ischemic stroke in vitro by implementing ischemia-like conditions through the hypoxia-glucose deprivation (OGD) method. After oxygen-glucose deprivation, we can perform several studies to analyze the different stages of the cell death process and the possible recovery of damaged neurons.

Ace Therapeutics is committed to developing 3D in vitro models of ischemic stroke to better reproduce the brain environment, helping you to achieve high-throughput screening and improve your chances of finding new and successful therapies.

In Vitro Modeling Hemorrhagic Stroke

Ace Therapeutics provides reliable in vitro models of hemorrhagic stroke for rapid and effective drug screening. We construct in vitro models of intracerebral hemorrhage (ICH) through a variety of methods, including hemoglobin, heme, autologous blood intracerebral injection, hydrogen peroxide, and glutamate. We also provide in vitro phenotypic assays including analysis of different parameters associated with cellular damage.

Frequently Asked Questions (FAQs) About In Vitro Models of Stroke

What is the most common method to mimic ischemic stroke in vitro?

The most widely used approach is oxygen–glucose deprivation (OGD), which simulates ischemia by removing oxygen and glucose supply. Reperfusion can be modeled by restoring normal culture conditions (OGD/R).

What is the difference between a co-culture BBB model and a 3D BBB model?

A co-culture BBB model typically uses 2D systems (e.g., Transwell) to study cell–cell interactions and barrier function. A 3D BBB model better mimics tissue-like structure and cell–matrix interactions, offering higher physiological relevance.

What is a BBB chip model and why is it important for stroke research?

A BBB chip is a microfluidic platform that recreates BBB function under dynamic flow and shear stress. It enables real-time monitoring of barrier integrity and drug transport, making it valuable for more predictive stroke-related BBB studies.

How do researchers measure BBB integrity in vitro?

Common readouts include:

  • TEER (Transendothelial Electrical Resistance) for barrier tightness
  • Permeability assays using fluorescent tracers (e.g., FITC-dextran)
  • Tight junction markers such as claudin-5, occludin, and ZO-1

Can in vitro stroke models be used for drug screening?

Yes. In vitro models of stroke are commonly used for early-stage screening of neuroprotective compounds, BBB-protective agents, and drug delivery strategies by evaluating barrier function, permeability, and cell survival outcomes.

How to choose an appropriate in vitro stroke model?

Model selection depends on research goal:

  • Co-culture models: simple BBB function and mechanistic studies
  • 3D BBB models: higher physiological relevance and 3D transport
  • BBB chip models: dynamic flow, real-time monitoring, advanced screening
