  "account": "In a groundbreaking development for biomedical research, scientists have created a lab-on-a-chip device that seamlessly integrates a human stem cell-based blood-brain barrier (BBB) model with neural organoids. This innovative combination offers a powerful tool for studying central nervous system pathologies and the delivery of nanotherapeutics to the brain.\n\nThe research team meticulously optimized the conditions for the BBB-NO integration under both static and dynamic conditions. By combining human stem cell-derived BBB co-culture models with human midbrain organoids within a microfluidic LOC, they were able to observe changes in both the BBB and neural tissue, as well as analyze the barrier and brain units independently.\n\nThe LOC design provided unprecedented insights, enabling phase contrast and fluorescent microscopy on the entire brain endothelial culture surface. This allowed for the precise measurement of barrier integrity and permeability across the BBB model, as well as the passage of molecules into the neural organoids.\n\nThe study demonstrated robust BBB-specific endothelial morphology, gene and protein expression, and maintained good barrier integrity - all key indicators of the LOC's engineering and cellular design. Crucially, the transport of targeted nanoparticles across the BBB model, followed by their entry into the neural organoids, confirmed the barrier integrity and transporter functionality of this dynamic integrated complex model.\n\nTo validate the translational potential of this BBB-NO model, the researchers used a clinically used hyperosmolar iodinated contrast agent, iopamidol, known for its neurological side effects. The results confirmed that iopamidol induces transient BBB dysfunction and neural effects in the complex system, thereby validating the model and highlighting the necessity to study BBB changes alongside NO functions. This landmark achievement opens up new avenues for translational research in the field of central nervous system pathologies.",
  "summary": "For advanced biomedical research, complex, well-described human blood-brain barrier (BBB) models are crucial for studying central nervous system pathologies and brain targeting of nanotherapeutics. Our aim was to establish and characterize a complex lab-on-a-chip (LOC) system integrating a BBB model with neural organoids (NO). We optimized the conditions for BBB-NO models under static and dynamic…",
