Summary
Advanced in vitro models using human induced pluripotent stem cells (iPSC) show promise for studying traumatic brain injury (TBI). These models better replicate human neurovascular units, aiding neurotrauma research and drug discovery.
Area of Science:
- Biomedical Engineering
- Neuroscience
- Stem Cell Biology
Background:
- Traumatic brain injury (TBI) poses significant challenges due to complex biomechanics and diverse cellular responses.
- Existing in vitro models (2D cultures, slices) lack human-specific architecture, vascularization, and neurovascular interactions crucial for TBI research.
Purpose of the Study:
- To systematically review advancements in in vitro traumatic brain injury (TBI) modeling.
- To focus on models utilizing human induced pluripotent stem cells (iPSC) and neurovascular unit (NVU) components.
Main Methods:
- Review of studies employing iPSC-derived neural and vascular tissues.
- Examination of organoids, hydrogel scaffolds, and microfluidic platforms for TBI simulation.
- Analysis of models incorporating mechanical injury and NVU integration.
Main Results:
- Integration of NVU components significantly enhances the physiological and functional relevance of in vitro TBI models.
- Human iPSC-based models offer improved recapitulation of TBI pathophysiology compared to traditional methods.
Conclusions:
- Emerging in vitro TBI models, particularly those using iPSC and NVU components, hold potential for advancing neurotrauma research.
- Key limitations include organoid maturation variability, incomplete vascularization, and lack of standardization, requiring future research focus for improved translational fidelity.
